The "Ramnit" computer malware is now targeting thousands of Facebook users and has already stolen thousands of users' login credentials. Security analysts say that the new variant of financial malware is spreading on the social networking website and is stealing account details for the social networking service. The malware was originally designed to track harvest information such as browser cookies and banking login credentials.

The malware in its new form as a Facebook infection had already compromised the accounts of tens of thousands of users. These accounts might be used to spread links and posts to compromise more accounts of users.

The malware is the latest of many that are seeking to use the social networking sites to spread to millions of users. The outbreak of malware shows a new trend of cyber criminals targeting users of social networks.

The new approach by cyber criminals aim to exploit that fact that social networking messages are usually more trusted than emails. Most popular emailing services have now prepared powerful filters for banning spam and viruses. Researchers believe that the malware's creators are looking to use the compromised Facebook accounts to expand their activities and target more users around the world.
