System Restore Explorer – View, Delete and Browse Inside System Restore Points
System Restore Explorer is small, freeware tool that allows you to
view and delete specific Windows system restore points. This is a handy
way to clear up some disk space without wiping out all of the restore
points since previously the only built in option we had was either all
or none.
However, the best feature is that it allows browse and copy
individual files inside the system restore points, without performing a
full system restore.
When you install System Restore Explorer, you see a list of all the
available system restore points including the time and date of when they
were taken. You can right click on any of these and you
have the option to Mount, Unmount or Delete that specific restore point.
If you Mount that restore point, it will show you the files inside that
restore point in your standard Windows Explorer interface allowing you
to manage the files inside it like you would any other file on your
system.
This application only works in Windows Vista and Windows 7.

How To Perform a Perfect BackUp & Reinstall with Apple Time Machine
Guest Post by Marco Rodi: Marco Rodi owns an IT Engineering university degree. He has his own computer repair business (OrdiRodi) that mainly does Apple Support.
So you receive a call from a client saying “My hard drive just crashed!!” or “I just bought a new Mac and I need to transfer all my information” or even “I want to clear my hard drive and do a clean installation”.
As a professional, you need to know exactly what to do to perform a
perfect backup and reinstall. You don’t want to lose a client’s files or
preferences. The client wants to have the exact same thing as before:
their beautiful Mac, up and running again. They do not want to call you
back and say: “Hey! I don’t have my music in my iTunes anymore!”, “Where are my bookmarks?” or “How come my icons are smaller?”.
Here are the steps to perform a perfect backup and reinstall on OSX using Time Machine.
First of all, you need to backup everything. With Apple it’s easy.
There is a built in application called Time Machine and you simply need
to plug an empty external drive into the computer (Yes, it must be empty
because it will wipe everything on it), and activate Time Machine.
To activate Time Machine, simply open your System Preferences. And click on the Time Machine icon.
Click on “Select Disk”.
Choose your external drive and click on “Use Backup Disk”.
Time Machine will copy everything (OS, Software, Files, and
Preferences) to the external hard drive. So when you will reinstall the
OS, you can restore everything from that backup.
Once everything is backed up, we need to clear and format the new
hard drive. To do so, you need to have a copy of the OS that you need to
install (Snow Leopard or Lion). It can be on either CD or USB, it does
not matter.
Shutdown the computer and insert your bootable device into the client’s Mac.
Boot the Mac while holding the “Option” key (ALT key if you are using
a non-Apple keyboard). You will arrive on a window where you can choose
a bootable device. Please choose your OS Installation (Either CD or
USB).
You will then arrive at this window. Choose the language you want and press enter.
Click on Utilities and choose Disk Utility.
Select the drive you want to format to the left.
On the Erase Tab, use the “Format” Dropdown and choose “Mac OS Extended (Journaled)”.
Name your Hard Drive
Click the Erase Button.
It will then take some time to format the hard drive.
Once this is completed, you can close the Disk Utility window and
start the installation. It will install the OS on your new hard drive.
Once the installation is complete, it will reboot and it will start from your newly installed OS.
At the beginning, it will ask you if you want to transfer your information.
Plug your external device with the Time Machine backup and select
“from a Time Machine backup” at the “Do You Already Own a Mac?” stage.
It will transfer all the files and settings that Time Machine made a backup of back onto the Mac.
So that is it. You can let your client test the computer and confirm that everything is back to normal.

Here’s a
rundown of the most important things I’ve been carrying around for a few years
now. All of the items I’ve listed have been lifesavers in one way or another.
For any software, I’ve included a link to download the ISO or title itself.
Hiren’s Boot CD –
Hiren’s is not a sole piece program but instead a compilation of some of the
most useful freeware utilities available to a computer repair technician. This
disc is very similar to Ultimate Boot CD which I also find to be a necessity,
but with the addition of two important pieces of software: Offline NT Password
Changer and Mini Windows XP.
The former
allows you to reset nearly any user password on a Windows system old and new
(NT through 7) and the latter is a WinPE-powered edition of Windows XP that
runs as a Live CD. It’s extremely useful for quickly backing up customer data
from a hosed Windows installation. You can also use it to test out hardware
that may be questionable in condition, like wireless cards, outside of a
client’s local Windows installation. There have been discussions surrounding
the legality of Hiren’s Boot CD, but since about version 13 of the disc, they
have removed all of the shareware or commercial software that caused
controversy.
Ultimate Boot CD – This disc is similar to
Hiren’s which I talked about above, but does have some different hardware
utilities that aren’t necessarily found on the former. The reason I keep this
in my arsenal is because, even when there is overlap in software with Hiren’s,
at times programs do not load correctly and just hang on Hiren’s. When this
happens, you have no choice but to give the programs a try off UBCD.
This
product has been in development for quite a few years, and was actually the
first utility live cd that I ever used. It may not be as expansive as Hiren’s,
but for what it offers, it’s a bullet proof tool that should be in your onsite
CD collection.
CCleaner – If there was one Windows-based
tool I could not live without, it would be CCleaner. This little tool is
completely free and constantly updated for more functionality. It’s a swiss
army knife for cleaning off temp files from a system; fixing broken/missing
registry entries; and providing a fast central location for uninstalling all
programs on a machine.
It also
happens to have a clean startup list manager which allows you to trim down
unwanted junk that loads on many of the PCs you work on for clients. I’ve been using
this tool for years and have yet to be let down. Give it a try if you are still
(*sigh*) using the Windows built-in tools for doing similar functions.
Reversible
Flathead & Philips Screwdriver – The reversible Philips/flathead screwdriver is
probably the single most used piece of hardware in my toolbag. Nearly every
computer case uses a mix of large and small screws, all of which can
(generally) be handled with this wonder of a tool. It saves space because it
includes reversible bits that cover large and small screw types for each
variety. A wise investment and a near necessity for any proper computer tool
bag.
Inline
Network Cable Tester – While
a traditional network cable tester works fine, the level of detail and
information afforded by something like a Fluke NetTool device is
unparallelled. This device allows you to check a multitude of aspects of any
Cat5/Cat6 cable or jack such as proper crimping, proper punchdown, continuity,
and passthrough functionality of an entire cable itself.
I
happened to pick up a Series I NetTool on ebay a few years back and consider it
well worth the $300 USD or so that it cost me. Don’t bother spending the $1000+
USD on a new device – these puppies are built like tanks and generally last a
long time. Save yourself time when dealing with network cabling & jacks and
consider an inline cable tester.
Utility
Knife – Brand
or make does not matter as much here. There is so much competition for these
knives that I merely recommend you have some sort of utility knife in your
toolbag. I happen to carry around a Leatherman as I prefer their higher
quality, but the choice is yours. These knives are very handy in cutting open
boxes onsite, cutting cabling, assisting with smaller sawing tasks, and general
everyday nuances that you come across onsite.
Trying to
replicate the functions of a single utility knife across separate tools would
be both a money waste and space loss. Plus, you can carry one of these in your
pocket when you are onsite without having to lug a toolbag all over to handle
separate tools.
Tape
Measure – Who’s
to say when you will need to get measurements of a short distance or when
scoping out a job? I use one of these to measure boxes I may need to ship, as
well as how long of a cable I’ll need for any type of installation. They are
handy, accurate, and you can even get ones in different shapes that offer
advanced features like lasers and the like. My recommendation is to stay with
something cheap (but not the cheapeast) as to keep thieves at bay.
2 Gallon
Air Compressor -
Before I get emails from people asking me how I fit this in my toolbag, I’m
going to say up front that I simply do not. It’s a companion tool that travels
alongside my toolbag to most customer locations, and beats compressed air for
cleaning out dust by a longshot. Not only does it provide for MUCH greater
pressure, but it saves money in the long run.
For 5-7
packs of compressed air, you could instead purchase a small portable air
compressor. My unit is a 2 gallon device and serves me well. Customers are
impressed with the professionalism of having such a device, and truly cleans a
PC better than any small can ever did. Works great on laptops too!
Floppy
Disks & USB Floppy Drive – Call me crazy, but as a PC tech, you NEVER know
when you will run into a situation that needs one or both of these items. I
needed to use a USB floppy drive just this week. Many older PCs and servers made
before 2004 still (sadly) require floppies to perform BIOS updates. I keep a
pack of brand new floppies in my bag, along with a USB floppy drive that has a
single disk loaded in at all times. You will be hardpressed to find new packs
of floppies in any store, but online sites like Ebay still carry them in
plentiful quantities for cheap.
USB
IDE/SATA HDD Adapter – Don’t
get caught onsite without one of these. I happen to use a Bytecc combination
adapter, but there are many different types on the market today. This tool can
be used to connect any IDE or SATA hard disk to a machine of your choice,
whether it be for emergency virus removal or worse yet – data recovery.
Whatever
the purpose, this little tool costs under $50 USD generally and is light enough
to be stuffed into a side pocket of any toolbag. For my office, I have a HDD
caddy that performs the same functions, but offers a drop-in bay for the hard
disk drive itself. Costs a bit more, but great if you are doing a lot of
workbench based virus removals or data recovery.
LED
Flashlight – Cheap,
portable, and super effective in low light situations. There’s no reason
anymore to debate about carrying around police-quality Maglites. These LED
powered flashlights that have become quite common over the last few years are
just as powerful for directed-light situations that need just a small surface
illuminated. Batteries last a long time in these flashlights so don’t worry
about the need to keep spares on hand. Any hardware store should have a variety
to choose from.

In this article you will learn all the most important boot shortcuts
on a Mac. We’ve all been there. The client is there, you boot their
computer and the screen just hangs there. No OS. You sometimes see the
grey apple logo, sometimes it’s all white and sometimes you see nothing
at all. You absolutely need to know which key to press in order to
repair the Mac. Enter the Apple Mac boot shortcuts.
First of all, you don’t have to use an Apple Keyboard to do these. Any
regular USB PC keyboard will work as long as you keep in mind the
following:
Option = ALT Key
Command = Windows Key
To make these boot shortcuts work, the computer needs to be shutdown
and you need to press/hold these keys while booting the computer.
C
Sometimes, the Mac is not programmed to automatically boot from a CD. This allows you to boot directly from the CD.
Option
By far, the most useful shortcut that will tell if the computer has a
hard drive failure or a motherboard corruption. When you hold option at
start, it will detect all the bootable devices in the Mac such as the
CD, Hard Drive, External USB and External FireWire. You can then choose
which devices you want to boot from. This is perfect if you want to boot
from an external USB/FireWire.
D
All Apple Computers come with an Hardware Test CD. When you hold D,
the cd needs to be already inserted. It will boot Apple Hardware Test
which is an incredible powerful tool that will make a precise diagnostic
on your client’s computer about any form of hardware failure: RAM, hard
drive, motherboard etc.
Option – Command – P – R
This combination will reset the NVRAM and PRAM of your client’s
computer. What does it mean? It will reset all the default settings on
the motherboard or built in features including: Serial Port
Configuration, Clock, Volume, Double-Click time, Virtual Memory, RAM
disk, Mouse Speed, Application Font, Alarm Clock, Monitor Color Depth,
Startup Disk and Serial Printer location. This is often done if your
client’s machine boots into a weird pink color. To do this NVRAM/PRAM
reset, your need to hold the keys when you boot your client’s Mac. Hold
down the keys until the computer restarts with the startup sound the
second time.
Hold the mouse or trackpad button
This will eject all the removable media plugged to your Mac. (Cd,
USB, Firewire etc.) This is perfect if the CD is stuck inside and the
keyboard is not working or if the Mac tries to boot from an unknown
external device.
Command-S
This will boot the machine in Single-User mode. It is a UNIX-like
interface where you can enter many simple commands to troubleshoot the
machine. This is mainly popular with the use of “fsck ” to check the
computer disk permission.
Command-V
This starts the Mac in Verbose Mode. You will see all the descriptive
text of all the boot steps, similar to Windows’s Safe Mode. If the
computer freezes on startup, you can see where it will freeze.
T
This puts the Mac in Target Mode. It will transform the Mac into a
giant Firewire external drive. You can access the files from another
computer. Perfect if you need to repair a corrupted hard drive or backup
files.
Shift
This will start the Mac on a safe boot. It will disable all the login
items, all the non-default fonts, disable all the cache and it will
force a directory check.
If you are still unable to enter the system or at least see the grey
Apple logo at the beginning after using these shortcuts, the problem is
most likely going to be a motherboard corruption.

The Social Engineering Threat to IT Security
Computer technicians know all too well of the security threats in the
cyber world. Virus and malware removal is usually on the most
in-demand services for computer repair businesses, especially companies
that service residential PC’s. Technicians who service small businesses
know the importance of securing networks, configuring firewalls, spam
filters, frequent software patches, and virus definition updates in
order to keep the vulnerabilities of the computing environment at a
minimum.
There are a number of hardware and software tools that are designed
to create a “secure fortress” of protection, with their main goals to
keep the bad guys from infiltrating a system and malicious software from
taking over. While these tools are necessary, there is one element
that they still can’t protect – the human element. A solid fortress of
hardware protection, updated anti-virus, and long cryptic passwords
won’t do any good if you simply give the bad guys (or girls) the
information they are looking for.
Social engineering is one the biggest threats (if not the biggest
threat) to computer security, whether in residential or business
environments. If computer technicians are to properly secure a computer
system or network, they must know about social engineering and how to
mitigate the attacks.
What is Social Engineering?
Social engineering is the process of gaining information through
human, interpersonal, behavioral, and psychological means. There are
two classifications of social engineering: technology based and human
based. Technology based social engineering is when a user is deceived
via a computer or device, usually through software, into believing
something is real when it is not. Human based social engineering is
when people are deceived or coerced by human interaction. Human based
attackers normally impersonate a legitimate role to gain access to
information; for example by impersonating an IT support technician, an
attacker may easily be able to get past the front desk of an office and
even gain access to the server room.
Whether technology based or human based, social engineering takes
advantage of the human condition. Attackers manipulate people into
providing sensitive and personal information by gaining their trust,
deception, and playing off of human psychological and emotional factors.
They use curiosity, fear, accomplishment, economic duress, economic
gain, the desire the help people, and friendship, to name just a few, in
order to easily extract information from the victim. Many times the
victim will be totally unaware that they are being attacked or have been
attacked. Social Engineering is akin to conning people.
A con-artist and a social engineer have very similar traits, although
social engineering can be used for good purposes also, such as ethical
hacking, penetration testing, security audits; and in non-technical
environments, such as doctors trying to get information for a correct
diagnosis, law enforcement asking certain questions in search for the
truth (or a confession), and parents trying to connect with their
children through discipline or teaching. Social engineering is not
always a bad thing, and can be applied to all those situations and more.
We, as security conscious computer technicians, however, need to make
sure we are aware with the dark side of social engineering.
The Social Engineering Framework
The social engineering framework website
provides a wealth of information regarding the art of social
engineering. They provide resources and information regarding what they
call the social engineering framework, which in summary contains the
following:
- INFORMATION GATHERING: Doing your homework! Researching as much about the mark as possible in order to become as believable as possible.
- ELICITATION: The process of extracting information or data from people.
- PRETEXTING: The act of creating an invented scenario to persuade a targeted victim to release information or perform some action. (Source)
- PSYCHOLOGICAL PRINCIPLES: Using human nature, psychology, and emotions to your advantage.
- INFLUENCING OTHERS: Persuasion tactics.
- SOCIAL ENGINEERING TOOLS: The website has a social
engineering toolkit that includes a software program based on Metasploit
with pre-defined templates used for security audits. Also explains the
use of other technical tools of the social engineer.
Typical Attacks
- Pretexting: Mentioned above.
- Phishing: Many times in the form of pop-up windows and fake websites
- Voice/IP/CallerID Spoofing: Using a well known or familiar voice or caller ID in order to gain instant trust.
- Baiting: Leaving a flash drive containing malicious
code in a public place, such as a hallway, bathroom, office floor, etc.
Human nature is curious and many people will insert the flash drive to
see what’s on it. especially if it has a label such as “financials,” or
“contracts.”
- Computer Viruses/Malware: Normally in the form of
rouge software, such as fake-anti virus programs that look real and tell
the victim to pay money for the program in order to delete the many
viruses on their pc. Other social engineering viruses are distributed
vial emails and intriguing attachments, especially if they are sent from
hacked friend’s account.
- Dumpster Diving: Careless people will through away
sensitive material in the garbage. There has been a lot of important
and private information gathered form simply digging through the
garbage.
- Shoulder Surfing: Secure passwords, PIN numbers,
and personal information can easily be found by people looking over your
shoulder. Many people are not aware that others are watching them or
simply don’t secure their environments enough to prevent it from
happening.
Payloads:The attacks can be technology based or
human based, and so can the payloads. The malicious scripts placed on
computers as a result of a successful social engineering attack can take
the form of: Rootkits, Backdoors, Keyloggers, Worms, and other Viruses
that pass information from the victim to the attacker, many of them even
giving the attacker direct access and admin rights of the victim’s
computer. Human type payloads can be access to private or locked down
environments, direct information gathering form the target, and simply
the trust of victim, which can lead to the attacker getting quite a bit
of information.
How to Mitigate Social Engineering Attacks
- Education is the number one tool for fighting
social engineering attacks. People need to be aware of the threats if
they are using the technology or are in a position where they need to
protect private information (this doesn’t mean they are a security
guard, it could even be a receptionist, or a regular home user). Many
times storytelling and/or showing videos of social engineering tactics
in action, both human-based and technology-based, are very effective.
- Password Management: Guidelines such as the number
and type of characters that each password must include, password
changing frequency, and a strict policy that employees should not
disclose passwords to anyone, not even IT.
- Two-Factor Authentication: When applicable, using more than one factor for authentication, such as a password and a key fob.
- Anti-Virus/Anti-Phishing Defenses: Multiple layers of anti-virus defenses, such as at mail gateways and desktops, can minimize the threat of phishing.
- Change Management: A documented change-management process is more secure than an ad-hoc process.
- Document Handling and Destruction: Sensitive documents and media must be securely disposed of and sanitized.
- Physical Security: The organization/client should
have physical security controls such as visitor logs, mantraps (to
prevent piggybacking), monitor placement, privacy screens, etc.
Stats
Here are some interesting security stats that relate to social engineering.
- This article found on massachusettsnoncompetelaw.com
states that a staggering 60% of employees interviewed admitted to
stealing data of one sort or another when leaving a job. Some of the
other statistics mentioned are:
“Most common (61%) is old-fashioned theft of paper documents or hard
files, followed by downloading information onto a disc (53%), onto a
USB memory stick (42%), and sending documents as attachments to personal
emails (38%). Interestingly, comparatively few employees ]were taking
information by stealing BlackBerrys and laptops. Another quite alarming
finding is that approximately 25% of the employees indicated that they
were able to access data on a company’s network even after they had
departed.”
- Another statistic from employeetheftsolutions.com
states that 75% of employees steal from their companies and lists the
top 10 most important things to employees, showing what they may be
disgruntled about.

(Source)
- The U.S. Chamber of Commerce estimates that 75 percent of all
employees steal at least once, and that half of these steal repeatedly.
The Chamber also reports that one of every three business failures is
the direct result of employee theft. According to the U.S. Department of
Commerce, employee dishonesty costs American business in excess of $50
billion annually.
- In an IT security survey, 90% of office workers gave away their password in exchange for a cheap pen.
- People are usually the weakest link in the security chain.
- Social engineering is still the most effective method used to get around security obstacles.
- A skilled social engineer will often try to exploit this weakness
before spending time and effort on other methods to crack passwords.
- An analysis for SANS estimated that nearly 10 million U.S.
households own a computer that is infected with some type of keystroke
logging program. Although not every PC user whose keystrokes are being
logged has experienced financial losses the analysis estimates that
organized-crime groups have access to roughly $24 billion in bank assets
from accounts associated with the owners of infected machines.
- A study by Google researchers analyzing fake AV distribution found
that up to 90% of all domains involved in distributing fake antivirus
software used social engineering techniques: (Source)

How to Remove a Rootkit from a Windows System
What is a Rootkit?
A rootkit is a software program that enables attackers to gain
administrator access to a system. On Unix/Linux system, this is called
“root” access. Rootkits contain tools and code that help attackers
hide their presence as well as give the attacker full control of the
server or client machine continuously without being noticed. Sometimes
they even cause typical malware type problems. I had a case where a
browser hijack was being caused by a particular rootkit installed on the
system. In this article, I will show you one way to remove a Rootkit
from a Windows system.
“Rootkits are usually installed on systems when they have been
successfully compromised and the highest level of access has been given
(usually root) Some rootkits refuse to be installed until the attacker
has root access, due to read and write permission to certain files. Once
the system has been successfully compromised and the attacker has root,
he\she may then install the rootkit, allowing them to cover their
tracks and wipe the log files.”
A typical rootkit consists of the following utilities:
- Backdoor Programs – login backdoors, telnetd etc
- Packet Sniffers – Sniff network traffic such as FTP, TELNET,POP3
- Log-Wiping Utilities – Bash the logs to cover tracks
- DDoS Programs – Turn the box into a DDoS client (Remember trinoo?)
- IRC\Bots – Bots used to take over IRC channels (Lame and annoying)
- Miscellaneous programs – May contain exploit, log editor
(Source)
Types of Rootkit
- Persistent Rootkits
A persistent rootkit activates each time the system boots. Normally these types of Rootkits are stored in the system registry.
- Memory-Based or non-Persistent Rootkits
Memory-based rootkits will not automatically run after a reboot; they are stored in memory and lost when the computer reboots.
- User-mode Rootkits
User-mode rootkits operate at the application layer and filter calls
going from the system API (Application programming interface) to the
kernel. These rootkits normally change the system binary files to
malicious code that redirects control of the computer to the creator of
the rootkit.
- Kernel-mode Rootkits
Kernel-mode rootkits hook to the system’s kernel API’s and modify
data structure within the kernel itself. These are the most effective
and dangerous types of rootkits. Kernal-mode rootkits are very difficult
to detect and can hide on a system without any indication of being
active.
- Bootkits
Bootkits are variations of kernel-mode rootkits that infect the
Master Boot Record (MBR). The malicious code can be executed before the
computer actually boots.
- FirmWare
A firmware rootkit infects a device or piece of hardware where code resides, such as a network card or the system BIOS.
Mebromi firmware rootkit http://blog.webroot.com/2011/09/13/mebromi-the-first-bios-rootkit-in-the-wild/
- Hypervisor
These are newer types of rootkits that are infecting the hypervisor
layer of a virtual machine setup. The hypervisor is basically the layer
between physical hardware (host systems) and the virtual system (guest),
although a type II hypervisor can be installed on top of an OS in order
to present a virtual layer to the virtual system. These rootkits can
intercept hardware “calls” going to the original operating systems.
How to remove the Rootkit
This is where it gets fun! There are different approaches and really
no single full-proof method, neither is it guaranteed that the rootkit
will be fully removed. As a matter of fact, there are some computer
security experts who simply recommend formatting the drive and
completely re-installing the operating system.
The Manual Method
This may or may not be more time consuming than trying to search
using an automatic tool. If you are familiar with legitimate Windows
services and programs and can pick out suspicious files, then this could
be the way to go. Many times, rootkit scanners will not detect rootkit
infections, especially if they are new, so this may be the way to go if
you don’t want to go straight to the nuke-and-pave solution.
Tools:
Technibble has a video on using Process Explorer and AutoRuns to remove a virus. Finding a rootkit would be a similar process using these tools.
Read here
for more on HijackThis and the HijackThis reader. Those tools can be
used to find suspicious processes and files and, each have a unique form
of analysis.
Here is a process for locating a rootkit via msconfig:
1. Open msconfig and enable bootlog.
In XP, goto Start > Run. Type in “msconfig” (without quotes). Goto the “boot.ini” tab and tick “Boot log”
In Vista and Windows 7, goto Start, type in “msconfig” (without quotes). Goto the “Boot” tab and tick “Boot log”
2. Restart the Computer
3. Open C:WINDOWS or C:WINNT and open ntbtlog and search for malicious files.
You can start by searching this short list from Computersight.com for the files starting with the following names. It may contain some random characters after it.
- rot
- gas
- gaopdx
- seneka
- win32k.sys
- uacd
- tdss
- kungsf
- gxvxc
- ovsfth
- msqp
- ndisp
- msivx
- skynet
Get the path of the file name: \SystemRoot\system32\drivers\BadRootkit.sys
For an exhaustive list of rootkits that you can search for, check out this Rootkit List from Bleeping Computer.
4) Open up a command prompt and disable file permission using either the CACLS or ICACLS command.
For e.g., type cmd in the Run box (XP) or search box (Vista/7) with
Admin privilages (in Vista and Windows 7 Hit Ctrl-Shift-Enter to enter
the command prompt as an Admin) and type
cacls C:WINDOWS\system32\drivers\BadRootkit.SYS /d everyone or
Icacls C:WINDOWS\system32\drivers\BadRootkit.SYS /deny S-1-1-0:FMRXRW
(cacls /d everyone denies permission to the files for all users, Icacls /deny Sid:permission can deny Simple or Specific rights)
5) Restart the computer
6) Search for the file in the following location and remove it
C:\WINDOWS or C:WINNT
C:\WINDOWS\system32
C:\WINDOWS\system32\drivers
Registry
Clear the temp, %temp% and prefetch folders
Source: Computersight.com
The Automatic/ Semi-Automatic method
You can check out a list of rootkit removal tools here.
I would first fire up TDSSKiller from Kaspersky. It runs a fairly
quick scan and TDSS variants are popular, so it may catch something on
the first attempt.
If the TDSSKiller comes up empty then try out GMER, which is a powerful and exhaustive rootkit scanner.
From there I like to use AVG’s Rootkit Scanner. This tool has
actually found quite a bit of rootkits for me. It’s also good to run it
after you have removed the rootkit to be thorough, although you could
do that with any of these tools. Another program worth mentioning at
this point is the new Microsoft Standalone System Sweeper Beta. There
has been some buzz that this tool has been fairly successful at finding
hidden rootkits.
If these rootkit scanners are not finding anything, or they do find
something but can’t delete it, then you may have to move to the manual
method. You can also keep trying other tools but there does come a
point when you have to evaluate if the time and effort is worth it or
you should either try a manual method, or perform a full re-installation
of the operating system.

ListDLLs – Analyze DLL Files
ListDLLs is a software utility that displays all the
DLLs loaded into processes. It’s great for diagnosing, blue screens
(BSOD’s), Viruses, malware, and other software related errors. ListDlls
shows you the full path names of loaded dll’s as opposed to names only,
which can aid in finding rougue dll’s that have legit names but are in
the wrong directory. The program also flags dll’s that have different
version numbers after being loaded than the version of the file on the
disk. This can occur when a program is updated after it loads the dll,
or in the case of a malware infection.
Another feature of ListDlls is that it will dump version information and
digital signatures, as well as an option to filter output. For example,
if you suspect a malware infection you can filter ListDlls to output
only unsigned dll’s.
ListDlls will work on Windows XP, Vista, and 7, as well as Windows Server 2003 and higher.
Usage
- listdlls [-r] [-v | -u] [processname|pid]
- listdlls [-r] [-v] [-d dllname]
- processname | Dump DLLs loaded by process (partial name accepted).
- pid | Dump DLLs associated with the specified process id.
- dllname | Show only processes that have loaded the specified DLL.
- -r | Flag DLLs that relocated because they are not loaded at their base address.
- -u | Only list unsigned DLLs.
- -v | Show DLL version information.

ProcDump – Analyze CPU Spikes
ProcDump is a command-line utility that allows the
technician to analyze and diagnose CPU spikes and hanging services.
ProcDump also includes hung window and unhandled exception monitoring.
The program will write a customized crash dump (.dmp file) based on the
technician’s entered parameters. A great feature about ProcDump is that
you can automatically set a specific CPU threshold for a process to hit
before the program writes a dump file. This means that the program can
run unattended and create a dump file at the exact time it causes
problems or an abnormal spike.
Here’s an example: you notice on a client’s computer that the
explorer.exe process spikes the CPU to 90 percent at random times
throughout the day, and you’d like to create a few dumps to analyze the
problem. Instead of sitting at the computer with task manager open
waiting to see a CPU spike, you can enter the following command to
create a dump file at three separate times when the CPU for explorer.exe
is at or exceeds 90 percent, and then write the dump files to the
c:\procdumps directory:
c:\procdump.exe -c 90 -n 3 explorer.exe c:\procdumps
The -c switch is the CPU threshold parameter. The -n switch tells ProcDump how many dump files to create.
You can get more granular in your parameter settings by adding how
long a process spikes the CPU before creating a dump file. Example:
c:\procdump.exe -c 90 -s 5 -n 3 explorer.exe c:\procdumps
The -s switch tells ProcDump the length of time the service needs to
spike the CPU at the threshold you configured before a dump is created.
Other interesting parameters include “-u” that treats CPU usage relative
to a single core, and “-w” which will wait for a specific process to
launch if it’s not running.

RAMMap – Physical Memory Analysis Tool4
RAMMap is a portable, stand-alone software tool that
allows you to see exactly how Windows assigns physical memory. The
tool does not just display memory usage on an application or process
basis, but it shows the the memory usage down to each individual file.
The technician can analyze the exact memory allocation of drivers,
dll’s, system fonts, cached files, and more.
The following tabs are available on the main RAMMap screen:
- Use Counts: usage summary by type and paging list
- Processes: process working set sizes
- Priority Summary: prioritized standby list sizes
- Physical Pages: per-page use for all physical memory
- Physical Ranges: physical memory addresses
- File Summary: file data in RAM by file
- File Details: individual physical pages by file
A technician will find RAMMap useful in troubleshooting system
slowdowns and memory issues by being able to see exactly what
files/programs are taking up the most memory, or if program files are
not being released from memory correctly. RAMMap can also help the
technician clean up a client’s computer of files, drivers, and fonts
that are taking up memory space but are not necessary.
HERE is In-Depth Explanation of the Use Count and File Summary Tabs from Technet.

TOR (The Onion Router) – Proxy Tool
TOR is a free client application that uses a network of multiple
encrypted tunnels to route your Internet traffic. You can install the
components to use TOR or download a standalone bundle that does not
require installation. TOR can benefit IT Professionals in several ways:
<\/span>
- To verify IP based firewall rules: Instead of needing to physically
go outside your LAN you can use TOR on an internal machine to fetch IP
addresses outside of your company’s block to test and validate your
firewall settings.
- To “remotely” connect to deployed services internally: A technician
can use Tor to remotely connect back to services, without the need for
an external machine.
- To bypass security policies for critical IT usage: Tor can allow
unfettered access to the internet while leaving standard security
policies in place.
- To work around ISP network outages: If an ISP is having DNS or
routing problems TOR may be able to bypass the problem areas allowing
you to connect to the internet, even though the ISP is malfunctioning.
- Performing Malware Analysis: IT professionals in charge of incident
handling/analysis may need to trace back the origins of malicious
software or breach attempt. TOR allows the technician to do this
anonymously for protection against retaliation attacks.
How to setup TOR
You can install TOR as a browser plugin or you can download a bundle
pack specific for your operating system. The necessary components are
TOR and a web proxy such as Polipo. You can add an additional layer of
security by using PuttY. The TOR bundles include the torbutton (plugin
for Firefox) and Vidalia (a GUI for TOR). Install, check that it’s
working, and explore anonymously.

SpaceSniffer – Disk Analyzer
SpaceSniffer is a free and portable application that will scan a
drive and give you a visual treemap of the contents on that drive. This
is useful for the technician who is trying to clean up data on a
system, or is looking to delete/move data from a full partition to
another with more space. What’s nice about this program is that you can
easily analyze what files are taking up the most space, in a visual
manner, and then use the interface to dig deeper into a directory or
file.
<\/span>
SpaceSniffer allows you to modify your searches in many ways. You
can look for specific types of files, such as .doc, or can look for
older files by using a condition such as “2years.” The main menu shows a
high level view of your data breakdown, and by clicking on a section
you can drill down to see more files and how much space each individual
file is taking up. You can even navigate the interface while a scan is
in process.
At first glance the layout of your data in a visual manner may seem
cluttered or bit confusing, but you quickly get used to it, and the
visual aspect helps you hone down unnecessary files with ease.
Here is a the feature set from the Website:
- Supports drag and drop
- Export module lets you produce customizable textual reports
- Intuitive structure layout, multiple views for different media
- Zoomable elements, navigate like a web browser
- The Windows folders and file popup menu is accessible by right mouse click
- It’s possible to restrict the view content by typing simple yet powerful filtering criteria
- Lets you temporary tag files with four different colors and perform filtering on them
- Different views of the same media can show differently filtered elements
- Customizable in geometry, colors, behaviors
- You can navigate even during the scan
- Smart cached scanning engine, multiple views, single scan
- You can refine a zoomed area by a secondary scan process, even with main scan active
- Reacts to file system events, keeps always in synch, warns you by blinking elements
- Can scan NTFS Alternate Data Streams
- It doesn’t clutter your registry, only a plain XML configuration file
- It’s portable, no installation required, just put the executable somewhere and let’s go

GParted – Free Partition Editor
GParted is a free and open source partitioning tool. It can run
within a Linux environment or can be booted from a live CD. GParted
supports multiple file systems and works great on servers in RAID
configurations.
GParted is very useful when a technician needs to re-size a
partition, re-format a drive (to a different file system), set the boot
flag to a partition, and perform other useful features. Recently this
program was used in a small business environment on two different
servers in RAID 5 configurations. Both servers were running Windows
Server 2003 and had a system partition (C: drive) size of only 12 GB.
<\/span>
Obviously this is too small for a system partition by current
standards, and it was at the point where these servers could not
download and install updates. One server had about 400GB of information
stored on it with a couple hundred free. We were able to successfully
boot into GParted and re-partition the drives on both of these servers
without any problems (boosted the C: drive partition to around 40GB).
I have used GParted many times on workstations and I can’t remember a
time when it has failed or I lost data. It’s a great tool that all
technicians should have in their toolkit. It can be downloaded as an ISO
and burned to a bootable standalone cd, and many times comes included
on multi-application boot/rescue cd’s.
Features
- Create partition tables (e.g., msdos, gpt)
- Perform actions with partitions such as:
- create or delete
- resize or move
- check
- label
- copy and paste
- Manipulate file systems such as:
- btrfs
- ext2 / ext3 / ext4
- fat16 / fat32
- hfs / hfs+
- linux-swap
- ntfs
- reiserfs / reiser4
- ufs
- xfs
- Enable and disable partition flags (e.g., boot, hidden)
- Align partitions to mebibyte (MiB) or cylinder boundaries
- Attempt data rescue from lost partitions
- Supports hardware RAID, motherboard BIOS RAID, and Linux software RAID.
- Supports all sector sizes (e.g., 512, 1024, 2048, 4096 byte sectors)

10 Must-have Open Source Applications for Computer Technicians
2011-08-05 17:48:41-04
Open source software is one my favorite tech topics. Linux is my
preferred operating system kernel of choice and I use it on my main
system (and virtualize other OS’s). I use it to run my business and I
use it as a tool while on the job no matter what type of system I am
working on. Here is a descriptive list of tools, systems, and
applications that will help you on the job or in the office that are
open source and will run in a Linux environment or live CD (based on
Linux). All of these tools are available for free.
1. Puppy Linux
– Puppy Linux is a live CD distribution that is small, lightweight, and
can be booted directly to RAM. It only requires 128 of RAM to run
(I’ve ran it on less and it worked fine to browse the internet) and is
pretty quick, even on aged machines. Puppy is my main tool when a
customer running Windows can’t boot or access their hard drive due to a
crash, virus, or system file corruption. As long as the drive spins and
is recognized in the BIOS, I can boot to Puppy and access the system
hard drive. I can then back up any data and copy it to an external
drive.
Linux can read NTFS and FAT file systems and ignores any file system
permissions set within Windows, so as long as the data is unencrypted,
you should be able to read, write, copy, and move. It’s a great tool if
you can’t boot a system due to a virus, but would like to backup/recover
any data before working on the system (just remember to check the files
on the external drive to make sure the viruses didn’t attached
themselves).
I was at an on-site job where my customer wanted to transfer all of
her data from her old PC to a newer one; however the C: drive was almost
full (literally a few MB’s free), not to mention whatever else was on
there. It took about 15 minutes to fully boot and navigating was
horribly slow. I took out my Puppy Linux CD, rebooted into Puppy, and
was able to backup what she needed in less time that it took to
originally boot into Windows! This was a huge time saver, and the
customer appreciated that!
2. Darik’s Boot and Nuke (DBAN)
– DBAN is a boot disk that will securely wipe a hard disk clean. It is
great for bulk destruction or emergency sanitation. DBAN writes random
data to the disk several times which ensures that the old data will
never be recovered. A very useful tool when you want to make sure the
data is totally erased.
3. GParted
– GParted is an open source partition editor that runs off of a live
CD. This is a fantastic tool that I have used many times to re-size
hard disk partitions with great success. It has no trouble recognizing
hardware and software RAID, and was recently used on servers at our
software company to allocate more C: drive space on some older machines.
No problems at all.
4. Virtual Box
– Virtual Box is an open source virtual machine application and, in my
opinion, the easiest to use. If you are new to virtual machines, give
this program a try. It runs in Windows, Linux, OSX, and Solaris My main
PC runs Linux Mint as its host operating system. When I need to use
Windows I run it in Virtual Box. I use it for test environments and as a
learning tool.
5. GNU Cash
– GNU Cash is open source accounting software that runs on Linux and
Windows. It is straight forward double entry accounting and is not
anywhere near as powerful as Quickbooks; however, it gets the job done
if your accounting needs are basic. GNU Cash is easy to use and set up,
plus it’s free! If you are starting out or looking for a cost effective
alternative (or Linux alternative) to Quickbooks, with less of a
learning curve, give it a try. I use it in conjunction with some custom
spreadsheets and honestly, it’s all I need (at least for now). My
accountant had no problems with my documents at tax time.
6. Clonezilla
– Clonezilla is an open source live CD application used to create disk
images. I have used it many times with no problems. You can create a
full disk image of a drive or drive partitions and save it over a
network or to an external device. Obviously, you can restore the image
from any of those devices as well. I keep this in my tool kit all the
time.
7. Reconstructor and Remastersys
– Reconstructor is an application that you can use to make customized
ISO’s of Linux distributions. For example, when you download Ubuntu you
get whatever applications and setup that the developers packaged into
the ISO. With Reconstructor, you can take a base Ubuntu ISO, delete
applications that you don’t want or add in applications that you need,
and create a brand new Ubuntu ISO.
This is great if you want to make a customized “repair” version, or
you want to keep an ISO backup with your added applications in case you
need to reinstall the OS. You may want to use the OS on an older
computer and want to lighten to load. Remastersys does the same thing,
but I am more familiar with Reconstructor.
8. Truecrypt
– Open source encryption software. Truecrypt can create a single file
on your drive that you can mount as a virtual encrypted drive, or it can
encrypt entire volumes. Anything that you put into a Truecrypt
file/volume will be encrypted, and you need to mount it to Truecrypt and
enter a password to decrypt. It’s a great tool for on the fly
encryption for flash drives or external hard drives. You can also use
it to encrypt Dropbox files for added security.
9. AVG Rescue Disk
– This is not an open source application, however; the AVG rescue disk
is a Linux based live CD that allows you to run a virus scan of the
system hard drives. It is a free download. You can also download
definition updates from the command line if you have an internet
connection. It’s worked very well for me, especially when you are
fighting a nasty virus and it’s difficult to boot to the OS.
10. System Rescue CD
– A Linux based live CD that includes many of the tools mentioned
above. It’s similar to the Ultimate Boot CD which contains many tools
and also has a windows version.

10 Must-have Open Source Applications for Computer Technicians

Secrets of Marketing – Creating Desire
In our daily lives we are exposed to thousands of advertising
messages every day, each promising us a better life, an easier time or a
faster way. Good marketers don’t sell products, they create desire, and
it is much easier to get someone to buy your product or service if
they’re convinced they already want it! In professional terms, desire
is defined as creating a gap between a person’s perceived state and
their desired state. When we perceive a “gap” we will try to close it,
some gaps are short (i.e. I am hungry) and some gaps are long (i.e. I
want to become accredited in X).
Whatever the case, a truly effective marketing campaign will not only
fill this desire, but they will actually create the desire in your
mind, sound kind of evil hey? Let me explain what I mean and maybe it
won’t seem quite so bad.
Imagine that you are sitting at home watching the TV, you’re sitting on
the sofa when all of a sudden an ad comes on explaining the disastrous
health effects can occur from sitting on a sofa that isn’t clean. Now
you know this information, your desired state has shifted to include
“Clean Sofa” and you are more receptive to any information which can
help close this gap, fulfilling the desire to remain healthy. This
example is a bit crude, but I hope it helps make my point. Before you
watched this commercial you were probably not aware of your sofa, and
much less likely to search for a solution.
So how can you use this information to help you make marketing
material for your computer business? Well, most importantly the key
issue here is education as the adage goes, “the more you know, the more you know you don’t know”
While I am not suggesting that you simply make people “afraid” to the
point of dependency, it can be useful to educate your customers in some
of the ways in which things can go wrong with their I.T. After all they
can’t ask you for a brand new backup system if they don’t know they need
one. The purpose of creating the desire is to present your company as
the ideal solution, thus making the consumer happy.
This desire doesn’t need to be inspired by fear or trouble, you can
create desire through positive motivators too. For example, you may say
something like “Businesses on windows 7 spend less than half as much on
service calls”. Here, the “desire” is created to spend less money, you
have shown them there is a way and obviously you are now in a position
to provide this service. Different people will obviously have different
motivations so creating desire can require some planning and research.
To give you an idea, in Australia, when trying to sell a product to the
“middle class” customer, marketers will try to position their products
alongside “upper class” products in an attempt to make the product seem
more elusive. This (apparently) exploits the desire for middle class
people to feel they are part of the upper class and is known as the
“upward pull” effect.
When creating the “desire”, try to put yourself in the shoes of your
customer. If possible do some interviews with some existing customers
and try to nail down exactly what is going through their minds when they
are using the computer. You may discover some really fascinating
insights which apply to a whole range of people. I don’t believe you
should simply exploit the fears of your customers, as your understanding
of their problems increases, so does your ability to provide a truly
valuable service.
In my opinion the “desire” you create with your advertising should
align with your business’ persona. For example, if you are a promoting a
light hearted and fun approach to IT then your advertising should
center around making life easier, reducing stress. Alternatively if you
are a professional outfit with serious claims and a premium service your
messages should center on efficiency, stability and productivity. If
you have clearly defined consumer segments, it would be a good idea to
create a separate set of communications.
Possible “Gaps” – Some ideas to get you thinking
- Antivirus Problems
- Lifetime of Hardware
- New Staff Education
- Scalability and Growth Options
- BSOD / any urgent problem
- Changing over key software
- Computer Speed Issues
- Long Term Support Options
- Power Failure Implications
- Backup Issues
- Trends in your clients industry
Ultimately if people feel like you can identify with them and fix
their problems they will be much more likely to give you a call.
Research and understanding will help you identify with people’s real
problems and help you create a more compelling argument. Just try not to
be as obvious a some companies if you are going to “create” the problem
in the first place!
WebBrowserPassView – Recover Passwords from Web Browsers
WebBrowserPassView is a small, portable and freeware utility designed to recover passwords from:
- Internet Explorer (Version 4.0 – 9.0)
- Mozilla Firefox (All Versions)
- Google Chrome
- Opera
Once WebBrowserPassView has gathered all the passwords from the
various browsers, it displays them in a single table with the URL the
password was saved for, what browser it was saved in and of course the
username and password.
From there, you can save it as a TXT file, export the table as HTML and
more. This product was created by Nirsoft and in true Nirsoft fashion,
the application is very easy to incorporate into scripts due to its
excellent command line support.
This utility works on any version of Windows, starting from Windows 2000, and up to Windows 7, including 64-bit systems.

Virtuous Hacking: Penetration Testing and Security Analysis Tools
Penetration testing is a fascinating subject. Learning how to
ethically hack a system in order to find vulnerabilities and prevent
malicious hackers from taking advantage of an exploit is a dream for
those who love to make money hacking but prefer not to wear orange
jumpsuits in an 8’x10’ cell. Let’s take a look at some of the tools of
the trade for the penetration tester, most of which are freely available
for you to tinker with.
PLEASE NOTE: There are laws restricting port scanning in many areas,
even if it’s not malicious. Know that if you you use these tools on a
system that you do not have permission to be on you will be subject to
penalties.
1. Metasploit
Metasploit is a free open-source security vulnerability scanner. In
the Metasploit framework you can actually develop and execute exploit
code against a machine or network.
The basic steps for exploiting a system using Metasploit (from Source)
1. Choosing and configuring an exploit (code that enters a target
system by taking advantage of one of its bugs; about 300 different
exploits for Windows, Unix/Linux and Mac OS X systems are included).
2. Checking whether the intended target system is susceptible to the chosen exploit (optional).
3. Choosing and configuring a payload (code that will be executed on the
target system upon successful entry, for instance a remote shell or a
VNC server).
4. Choosing the encoding technique to encode the payload so that the
intrusion-prevention system (IPS) will not catch the encoded payload.
5. Executing the exploit.
The two most common payloads generated from Metasploit are:
1. Command shell that enables users to run scripts and commands against the host.
2. Meterpreter enables users to control the screen of a host machine using VNC.
Metasploit can also import vulnerability scan data and compare the
identified vulnerabilities to existing exploit modules for accurate
exploitation.
Armitage is a graphical interface front-end to the Metasploit framework that makes it easier to carry out security attacks.
2. NMap (Network Mapper)
NMap is an open-source network scanner (port scanner) that finds
host, services, and port information. You can use NMap to scan a
network for open and insecure ports, host systems, and servers. It can
also be used for simple network inventory and maintenance by detecting
operating systems, versions, and even hardware information. It’s fairly
simple to use, yet very powerful in the hands of an experienced
technician/hacker.
3. Nessus
Nessus is a proprietary vulnerability scanner. They offer a free
version for personal and non-commercial use. Commercial and enterprise
usage requires a license fee. Nessus can be used for auditing a
network, vulnerability discovery, compliance verification,
misconfiguration, and more. The software can also launch third party
tools to hack passwords (Hydra) and scan ports (NMap).
4. Wireshark
Wireshark is free and open-source packet analyser (commonly known as a
packet sniffer). Basically it will report and capture any traffic
within a network. Data can be captured and read later or you can watch
packets in real-time. Wireshark is a great tool to assess network
bog-downs, malicious/suspicious traffic, protocol analysis, and even
capturing raw USB traffic (currently available only in Linux).
5. Cain and Abel
Cain and Abel is a password recovery tools (password cracker) for
Windows. It uses dictionary attacks, brute-force, and cryptanalysis as
well as methods to decode encrypted passwords.
6. John The Ripper
John the Ripper is a password cracker that will run on Linux/UNIX, Mac OSX, and Windows. It is free and open source software.
7. Snort
Snort is a free and open source network intrusion prevention system
(NIPS) and network intrusion detection system (NIDS). Snort uses
signature, protocol, and anomaly-based inspection methods to detect
malicious traffic trying to enter or probe a network. It can also be
used as a packet sniffer and a packet logger. Snort will run in a
Linux/UNIX and Windows environment.
8. Kismet
Kismet is a powerful packet sniffer, and intrusion detection system for 802.11 wireless LANs.
“Kismet identifies networks by passively collecting packets and
detecting standard named networks, detecting (and given time,
decloaking) hidden networks, and inferring the presence of nonbeaconing
networks via data traffic.” – http://www.kismetwireless.net/
9. HPing3
HPing3 is a supercharged version of the Ping command utility. HPing3
can use TCP, UDP, ICMP and RAW-IP protocols other that just ICMP (as
ping). It also has a built in traceroute mode.
“This tool is particularly useful when trying to traceroute/ping/probe
hosts behind a firewall that blocks attempts using the standard
utilities.” -http://sectools.org/
Rootkit Detection and Removal Tools
2011-08-15 09:19:20-04
Rootkits are becoming more prevalent and more difficult to find.
Technicians need to be aware of the best software tools that will detect
and remove this elusive software. Here is a list of rootkit removal
tools that will work on the major operating systems.
Windows Based
Rootkit Revealer
Rootkit Revealer is part of the sysinternals suite and is a free
portable rootkit scanner. This tool was featured as a repair tool of
the week.
Download
Sophos Rootkit Scanner
Sophos offers a suite of security software but most notably they have a free rootkit detector and removal tool available here:
Download
GMER
GMER is a powerful rootkit scanner and usually my first “go-to” rootkit
scanner when I suspect suspicious activity above and beyond typical
malware. It’s quite small and portable.
Download
TDSSKiller
A great free tool from Kaspersky. It’s portable and easy to use with a
simple GUI. This tool recently helped me find a rootkit that was causing
multiple browser hijacks. I could not find the rootkit with any
malware scanner, HijackThis, Process Explorer, or a couple other rootkit
scanners. I ran this tool and it found it almost instantly (this
particular rootkit was part of the rootkit.win32.TDSS family).
TDSSKiller will search for the win32.TDSS family of rootkits as well as
bootkits (MBR rootkits/malware) and other suspicious services.
Download
Microsoft Standalone System Sweeper Beta
This is a fairly new application (still in beta!) that you can boot from
a cd or flash drive. It is meant for situations where you can’t boot
into a pc due to malicious software/activity. The program detects and
removes rootkits and other malware.
Check it out here: Download
(NOTE: This is an excerpt from the Microsoft website regarding
licensing for the System Sweeper Tool. Please read the license
agreement at the bottom of the page or contact Microsoft for more

AVG Rootkit Scanner
This is the rootkit scanner that comes bundled with AVG anti-virus. It
was only available in the paid version up until AVG 2010 was released;
now it comes bundled with the free anti-virus download. In my
experience it works pretty well and has detected some rootkits that went
otherwise unnoticed. Most well known anti-virus suites do come with a
rootkit scanner.
Download
Prevx
Prevx offers a suite of paid security tools; however they do offer a free trial version that includes a rootkit scanner.
Download
RootRepeal
RootRepeal is a rootkit detector that seems to be in a perpetual beta,
so use it at your own risk and take precautions. It has an advanced
rootkit detector for Windows XP and Vista. This was also featured in a
Repair Tool of the Week Article
Download
Linux and Apple Mac OSX Based
Let’s not forget our Unix based systems! It’s fairly slim pickings
for rootkit scanners on these operating systems, but there are two that I
know of that work well. As the popularity of these systems continue to
grow I believe we will be seeing more security concerns, hence more
tools.
chkrootkit
A rootkit detector that searches system binaries for modifications.
Download
rkhunter
This is a free tool that will search for backdoors and exploits by comparing MD5 hashes and strange file activity.
Download
Mobile Platform
Lookout Mobile Security
Lookout is a security application for Android, Windows phone7, and
Blackberry mobile devices. It isn’t necessarily a rootkit tool but I
wanted to include a security tool for the ever increasing mobile
platforms. The more a platform grows in popularity the more it will be
attacked.

Partly Cloudy with a Chance of Efficiency
"The cloud" has become the new buzz phrase in the technology industry
and whether or not you like the idea of using the Internet as a base
camp, there are some cloud based tools that can increase your
productivity, save you time (and money), and increase efficiency within
your business. There are many tools out there, so allow me to introduce
five tools, either cloud based or used in conjunction with cloud based
apps, that I have been using in my business and professional life.
1. Dropbox
– This is my favorite cloud based program/app. You can install it on
pc’s and laptops running Windows, Mac OS, and Linux. It is available in
many mobile formats as well, including iPhone and Android platforms.
Anything that you drop into your Dropbox folder on any one device will
automatically sync to your other devices where Dropbox is installed.
This is fantastic when there’s a pdf file that you want to read later or
when you have a file that you started in on one device and need to
finish on another. I now keep all of my business cards in a "business
card" folder within Dropbox. I don’t see any need to keep paper
business cards around since utilizing this tool. I can access a clients
card from my mobile device or from any pc/laptop where Dropbox is
installed. Best p
art is that Dropbox allows 2GB of storage for free! If you refer
people to sign up both parties get an extra 250MB and they allow you to
get up to 8GB free with this method. I only keep small files and JPEGS
in Dropbox, but for more space you can upgrade to paid plans with more
storage.
TIP: I am well aware of the recent news about
Dropbox’s security (or lack thereof). You should definitely think ahead
about what files you are saving to the cloud. The files that I use
within dropbox are not highly sensitive and the benefits of efficiency
outweigh the risks in my case. However, for files that may be more
sensitive you can use open source Truecrypt
to create an encrypted fileholder. I keep a small Truecrypt file
within Dropbox just in case I want to drop in something that requires
more security. If anybody accesses my Dropbox they will not be able to
decrypt anything in my Truecrypt file since I alone hold the private
key.
If you are a Linux user making backups to Dropbox you can use a program called DejaDup that encrypts your files to the cloud and allows for incremental backups.
2. Tomboy Notes
– Available for Windows and Linux. Tomboy is not technically a cloud
based tool (yet); it’s actually a desktop note taking application.
However, it does have web sync capabilities. The development team is
working on a Tomboy server where you can type notes and it will sync
directly to your local Tomboy apps, but it’s still unstable.
I use it in conjunction with Dropbox which allows your notes to sync
up flawlessly while basically keeping a backup in the cloud. I love
tomboy notes because: 1) it’s available for Linux; my main OS kernel of
choice. 2) It is small, simple, and intuitive; just install and use with
little to learn. 3) It automatically saves and links to other notes. 4)
It’s free.
I have just about ditched using paper for note taking, I use Tomboy
instead. Click "new note", type what I need, hit sync, and close. I
can print if I need to or keep notes open like sticky notes on my pc.
The only downside thus far is that there is no app for a mobile device,
although you can read the synced files in Dropbox that are in XML format
if you really need to look at a note.
TIP: Here is a quick tutorial on how to sync Tomboy notes using Dropbox.
3. Evernote
– Available for Windows, Mac, and most Mobile devices. Evernote is a
powerful note taking tool and cloud based app that will sync with all of
your pc’s and devices. It offers many more features over the
simplistic Tomboy app and is comparable to Microsoft OneNote, althoughh I
have found Evernote easier and more intuitive than OneNote which is why
I am recommending it.
Evernote is awesome as a mobile app! I frequently use it’s camera
feature to snap a shot of a business card, receipt, written note, etc,
then use it’s integrated Dropbox feature to upload into my Dropbox.
Seconds later the file is synced to all of my devices. I cannot tell
you how much this has reduced clutter and made my business (and life)
more efficient. You can also save voice notes as well as typed notes.
Evernote is what I use to type notes on my mobile device since Tomboy
isn’t available yet. It is also great for clipping notes, articles, and
pictures from websites and then syncing to use later.
4. Voltage Secure cloud email – Voltage secure email is a cloud based email encryption tool.
We implemented this tool in order to send securely encrypted emails
to our hospital and healthcare customers. Voltage is HIPAA compliant
(regulations in the USA regarding patient privacy) and most of our
hospital customer are already using it internally. The current cost is
$65.00 per license, per year. The reason that I like this tool so much
is that it does not require the recipient to install anything, such as a
private key or a certificate, nor do they have to be using the same
software. It is cloud based and both parties only need a web browser
(though there is an Outlook plug-in that creates a "Send Secure" button,
making it very easy to use with that mail client). The first time when
you send a Voltage encrypted email to somebody they will receive a link
to the Voltage website in order to create a login and password. Once
the information is verified they can open and decrypt the message using
their voltage credentials. This is extremely useful when
dealing with healthcare clients because getting healthcare IT
departments to install anything within their environment requires
nothing short of a miracle! Sensitive data requests can now be easily
transferred via email and is easy for the non-tech savvy recipients to
use.
5. Kindle (app). The Kindle app is available on
Windows, Mac, and most Mobile devices. I am including this here because
I consider the Kindle an extremely useful business tool with great
syncing capabilities. Learning is an essential business process. I
don’t know of many successful business owners (at least the ones I want
to emulate) that haven’t cited reading as a key to their success. The
Kindle app is useful because you can download an e-book on any device,
whether it be the Kindle e-reader itself, or one of the free Kindle apps
available for Windows (PC), Mac, iPhone/iPod Touch, Blackberry, iPad,
Android, and Windows Phone 7, and the e-book will sync to all your
devices where you have the app installed. Recently this came in handy
for me as I found myself sitting in a doctor’s office waiting room for
over an hour. I didn’t have my Kindle device on me at the time, but did
have my iPod touch and was able to conti
nue reading Daymond John’s "The Brand Within" not missing a beat.
Plus, you don’t need to be online as long as you sync the app ahead of
time. You can no longer use the excuse that you don’t have time to read
because Amazon has given us the opportunity to read anytime, anywhere,
on almost any device.
The other great thing about the Kindle app is that your notes and
highlights are also synced across all of your devices. If you read
something that is useful for your business while reading your Kindle on
the beach, highlight it or type a note. Later when you’re in the office
and your Kindle is home you can access your note/highlight on your pc
or mac. I have found the Kindle app extremely helpful for keeping my
reading notes organized, which allows me to be more effective in
applying what I learn into my business, especially when part of my
business is writing articles!
