Worm Attacks 45,000 Facebook Users

The worm called ramnit affects most are the people from France and United Kingdom.  It is capable of infecting Windows executables, Microsoft Office, and HTML files, according to McAfee.

"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," Securlet said in its bulletin. "In addition, cybercriminals are taking advantage of the fact that users tend to use the same password in various web-based services (Facebook, Gmail, Corporate SSL VPN, Outlook Web Access, etc.) to gain remote access to corporate networks."
