A computer worm has stolen 45,000 login credentials from Facebook, security experts have warned. Social networks offer rich pickings for hackers because of the huge amount of personal data that is stored on them. Increasingly malware is being updated for the social networking age. The latest iteration of the worm was discovered in Seculert's labs.
According to Seculert, 800,000 machines were infected with Ramnit from September to the end of December 2011. It won't automatically be noticeable that you have been attacked. The worm is stealing passwords so it is not going to announce itself,said Graham Cluley, senior security consultant at Sophos. In July 2011 a Symantec report expected that Ramnit worm variants accounted for 17.3% of all new spiteful software infections.
