New alert for social networking sites as 'Koobface' virus jumps from Facebook to Bebo
A virus which generates false messages from infected Facebook users in a bid to get credit card and other personal details has now spread to another social networking site.
The 'Koobface' virus is now on the prowl for unsuspecting users of the Bebo social blogging site - which claims 45 million users worldwide.
Members receive 'messages' from their friends with subjects such as 'You look awesome in this movie'. Following the link prompts them to download updates, such as an updated video player.
Once infected, the virus will lead them to contaminated sites when they try to use search engines such as Google or Yahoo.
Virus scanning company ScanSafe spotted the virus's jump to Bebo.
They said the virus accounted for 1 per cent of their blocked malware within the last two weeks.
Mary Landesman, senior security researcher at ScanSafe, said: 'Those who click on the link will be greeted with a message that they need to update their Flash player to view the ‘video’. There is no video nor is there an update - it is all just a ruse to get users to infect their own system by installing the Trojan.'
'It is particularly concerning for users that rely on signature-based anti-virus alone as they may not be picking up on this virus immediately.
'Worryingly, with this Trojan new versions are constantly being released by its authors.
'The same advice over the past half dozen years still remains true: don’t click on links in emails received unexpectedly, even if that email appears to be from someone you know.'
Social network MySpace, owned by News Corp, was hit by a version of Koobface in August and used security technology to eradicate it. The virus has not cropped up since then.
Facebook has told members to delete contaminated e-mails and has posted directions at Facebook Security | Facebook on how to clean infected computers.
