Think twice before you click on any photo links that you receive from your Facebook friends. Danish security researchers at CSIS have found a worm spreading via Facebook that delivers a variant of the Zeus banking Trojan, among other malware. Zeus can steal banking information and other sensitive account data by logging keystrokes.

Compromised accounts are spreading the worm by posting infected links with a .jpg extension. This obviously is a common photo file extension, so the danger of infection is quite high. The malicous file is not an image at all, but a malware laden screensaver. Too make matters worse, anti-virus software often fails to detect threats of this nature.

Users have to download and open the file for the infection to occur, so  Happy Clickers beware!

Take a few moments to confirm your friend did indeed send any links you might receive. This small act could save you an enormous amount of trouble down the road.

As always, Be careful what you click!
