Facebook Users Targeted

Posted in Anti-Malware Tools, Email Security, Exploits, Malware, Root kits, Scams, Security Tools, Spam on March 21st, 2010

FaceBook is very popular and there are about 400 million FaceBook users around the world.  Experts believe millions of users will fall for this attack and get infected.  Yes, that’s right – millions of FaceBook users will be infected by this targeted attack.

Unfortunately, 400 million users makes for a big opportunity for delivering malicious software.  Hence, Inboxes all over the world are being flooded with SPAM that is trying to induce FaceBook users to click on an attachment.  This attachment installs Trojans and other malware that is very dangerous to the computer user.   And unless their security software catches it, they will have no idea it is on their computer.

Our advice:

  • Never clink on any link or open any attachment in any email that warns of dire consequences – be it about FaceBook or your bank, or anything else.
  • Keep your anti-virus software up-to-date.
  • Periodical scan your computer with a tool specially made for finding and eliminating malware.  One of the best is MalwareBytes Anti-Malware freeware version, which can be downloaded from http://www.malwarebytes.org/

Storm Worm Spam Email Remains Very Dangerous

Posted in All Posts, Email Security, Exploits, General, Malware, Root kits on April 13th, 2007

The storm worm remains very dangerous and is the most prolific SPAM in recent history.

It’s success is undoubtedly related to the clever social engineering that it uses to entice people to open the attached .zip file.

It warns the user that their computer is infected and their email will be cut off if they don’t install the attached “patch”.

Ironically, the “patch” actually installed the Storm Worm Trojan, and the user will indeed be infected.

For more info please refer to the Computer World article.

Beware the Storm Worm

Posted in All Posts, Email Security, Exploits, Malware, Online Security, Root kits, Scams, Security Tools, Wired Network Security, Wireless Network Security on January 22nd, 2007

A massive storm that swept across Europe last week…

And then in it’s wake was a storm across the Internet – in the form a series of virus infected emails.

And reference our previous Post, clearly there is a serious lacking of “Street Smarts” among computer users because this virus spread like wildfire.  Check out the F-Secure video post on YouTube, and see for yourself.

All users are advised to update their anti-virus programs and use caution when opening email, and especially email that refers to current events in the news* and induces the recipient to open the attachment.  Some examples:

230 dead as storm batters Europe.
A killer at 11, he’s free at 21 and…
British Muslims Genocide
Naked teens attack home director.
U.S. Secretary of State Condoleezza…
  Russian missle shot down Chinese satellite
  Russian missle shot down USA aircraft
  Russian missle shot down USA satellite
  Chinese missile shot down USA aircraft
  Chinese missile shot down USA satellite
  Sadam Hussein alive!
  Sadam Hussein safe and sound!
  Radical Muslim drinking enemies’ blood.
  U.S. Secretary of State Condoleezza Rice has kicked German Chancellor Angela Merkel
  U.S. Southwest braces for another winter blast. More then 1000 people are dead.
  Venezuelan leader: “Let’s the War beginning”.
  Fidel Castro dead.
  Hugo Chavez dead.

The virus package that this email can load on your computer is nasty.  But users of infected computers may not even be aware that they are infected
Please note that this series of virus infected emails has a variety of subject lines and may contain several different attachments.

For more information, check out the F-Secure Blog.  They have posted a video of the infection spreading across the globe, and also provide detailed information as to the contents of this virus infected series of email.

  The Dance of Love
  The Miracle of Love
  All For You

  I am Complete
  Wrapped Up
  Moonlit Waterfall
  A Little (sex) Card
  A Special Kiss
  Hugging My Pillow

Firewall for Your Hard Drives

Posted in All Posts, Anti-Malware Tools, General, Root kits, Security Tools on November 6th, 2006

DriveSentry, by Drive Sentry Inc., creates a white list of programs that are allowed to write to your hard drives. 

If any program that is not on the list attempts to add or modify a file on your hard drive, Drive Sentry will intercept that action and ask for your input on the matter.  If a virus or other malicious program is attempting to access your files, you have an opportunity to block it.  Quite handy.

DriveSentry can also be used to prevent rootkits and keyloggers from writing to the hard drive, and it works with peripheral storage devices like USB drives.

DriveSentry is available for download from the maker at the following link:  http://www.drivesentry.com/index.htm

We haven’t tried this program yet, but plan to give it a test in the near future.  It looks promising.
