Zeus Trojan Returns on Facebook

Virus first surfaced in 2007 and has infected millions of computers

The infamous Zeus malware has once again resurfaced, but this time it's using Facebook to further its crime spree. First detected in 2007, Zeus has infected millions of computers over the past six years. Despite the efforts of numerous security firms to combat the Trojan horse, it has only gotten stronger with age.

Following the initial infection, the virus lays dormant until an online banking site is opened. It then uses keyloggers to steal the unsuspecting victim's usernames and passwords. Sometimes the Zeus malware goes even further - it replicates the bank's website, using a fake interface to obtain social security numbers, credit card digits, and other sensitive information. Eurograbber, a Trojan that employs similar methods to that of Zeus, reportedly stole $46.5 miillion from European users.
