The worm spreads itself via messages sent to Facebook users. Usually, the spam messages have “You look so funny on our new video” (or something very similar) as their title and contain a link to an alleged video site.
When the user tries to view the promoted video, he gets a message to install the so-called latest version of Flash Player or else he won’t be able to play the content.
As expected, the “update” the user would be downloading is in fact plain old malware. Once ifnected, the user can expect to be redirected to other contaminated sites or have its banking details stolen.
Facebook warns its users to use the latest antivirus software, as well as to keep away from messages sent by bogus “friends”.
