Facebook Malware Now Attacking Twitter Accounts

BitDefender malware researchers have identified a new variant of the Koobface worm, which now affects Twitter user accounts.

Previously known to
compromise Facebook and Myspace accounts, the new variant is spreading via malicious links posted on compromised Twitter accounts.

 

In order to infect the
user, the worm posts links to fake Youtube videos asking users to upgrade their
version of Flash player. Instead, it installs an infected binary that seizes
control over the user’s Twitter account and starts posting malicious links on
their behalf.

Twitter has
already started blocking accounts posting messages such as “My home video”
followed by hyperlinks. BitDefender has already released an emergency update to
protect against the newly-discovered vulnerability.

Other
details about the worm will be posted soon!
