Most of the hacked accounts are based in the UK and France.
Over 45,000 Facebook user accounts, mostly from the UK and France, were recently infiltrated by a worm attack. The malware, called Ramnit, was discovered in 2010, siphoning off FTP credentials and browser cookies from infected machines. In 2011 alone, the worm had affected 800,000 Windows-based PCs. A report from Seculert goes on to add, "We suspect that the attackers behind Ramnit are using the stolen credentials to log-in to victims Facebook accounts and to transmit malicious links to their friends, thereby magnifying the malware's spread even further. In addition, cybercriminals are taking advantage of the fact that users tend to use the same password in various web-based services to gain remote access to corporate networks".
Seculart has notified Facebook of the attack and has also furnished the social networking website with details of all the stolen credentials found on the worm's command-and-control server.
I had an issue with my competition page account. Whenever a user post a link on that page it comes up with a thumbnail image not very appropriate. Could this issue be related to this worm if yes do you have any solution mentioned for it.
