Facebook users suffer viral surge
|Facebook has been targeted by malicious hackers seeking to steal valuable data from members.
The social network site has been hit by five separate security problems in the last seven days, say security experts....
The rogue applications on Facebook all try to steal saleable information from the profiles of those who open it up, said Mr Ferguson.
One malicious application tried to trick people into adding it by claiming that their friends were having trouble looking at their profile. If the application is added it spams itself to every Facebook friend that a member of the site has.
...Hitting Facebook users alongside the rogue applications has come a sophisticated variant of the Koobface virus that debuted in December 2008.
The new variant uses a Facebook message to try to get people to visit a fake YouTube page and install the malware. To make it look more plausible, said Mr Ferguson, the virus posts the image from a Facebook member's profile on the video page.
Once installed the malicious program hunts for cookies on a victim's computer and uses the details it finds in the small text files to log into other social sites that person may be a member of.
