Security specialist Kaspersky Lab says it has detected two cyber attacks targeting the users of MySpace and Facebook. The worms transform victim machines into zombie computers to form botnets.<\/p>\n
Although the worms are only infecting MySpace and Facebook users, Kaspersky Lab warns that they could spread. <\/p>\n
Net-Worm.Win32.Koobface.a spreads when a user accesses their MySpace account. The worm creates a range of commentaries to friends’ accounts. <\/p>\n
Net-Worm.Win32.Koobface.b, which targets Facebook users, creates spam messages and sends them to the infected users’ friends via the Facebook site. The messages and comments include texts such as Paris Hilton Tosses Dwarf On The Street; Examiners Caught Downloading Grades From The Internet; Hello; You must see it!!! LOL. My friend catched you on hidden cam; Is it really celebrity? Funny Moments and many others.<\/p>\n
Messages and comments on MySpace and Facebook include links to YouTube.pl but when clicked redirect to a YouTube.ru site. The site then encourages users to upgrade their Flash player. Instead of Flash, however, the site installs a file called codesetup.exe.<\/p>\n
"Unfortunately, users are very trusting of messages left by ‘friends’ on social networking sites. So the likelihood of a user clicking on a link like this is very high", says Alexander Gostev, senior virus analyst at Kaspersky Lab. <\/p>\n
