Koobface Worm Turns Toward Twitter

McAfee Avert Labs has received a new variant of the Koobface worm. Unlike the previous variants, this one spreads using Twitter by sending fake tweets.

These fake tweets contain links to a video; some of these videos are named “My home video.” When users click these links they are prompted to install a video codec. However, upon following the instructions it actually downloads a variant of the Koobface worm and installs it.

At McAfee we detect this variant as W32/Koobface.worm.gen.e and W32/Koobface.worm.gen.h. The detection for this variant will be available to the public in today’s release (DAT 5675).

    It seems such worms could be easily diffused if their ability to multiply is challenged by an adjustment in client-side scripting practices. I have written the SAFE Model for exactly these types of cases:
