Checkers and Pogo writes "Grayware inhabits a murky area between pure malware and useful apps, and it's a growing problem. 38.1% of all malicious PC software falls into the grayware category, and so-called 'grayware 2.0' is targeting social-networking sites. Ars Technica's Jeremy Reimer notes, 'The "threat" of rogue applications like SuperWall wasn't immediately obvious: they seemed more like annoyances than real security risks. But as users entered more and more personal information into their Facebook accounts, it became clear that the possibilities for abuse were rampant. For example, because Facebook allows users to "tag" photos with the names of friends, it is possible for third-party apps to distribute photos that a user might only want to be seen by their inner circle of friends.'"
