Social media as an attack vector is not a stretch. A group of researchers from Greece have created a tool that can be used to attack users.
From vnunet:
In a paper entitled Antisocial Networks (PDF) the researchers demonstrated an application that causes Facebook users to unknowingly participate in denial-of-service (DoS) attacks against other sites.
The ‘Facebot’ tool was disguised as a National Geographic ‘picture of the day’ application which users install into their Facebook profile page, thus allowing it to access account information and request new photos.
This type of thing has been discussed for a while in the media and with talks such as Shawn Moyer and Nathan Hamiel’s “Satan is on my friends list” at Black Hat last month.
Not entirely new on the face of it but, interesting nonetheless.
