Symantec Security Response has found a new threat that spreads through, which is a very popular Social Networking Site in China ala Facebook. The threat comes in a form of a Flash video, which pretends to be a famous Pink Floyd promotional video clip "Wish you were here."

Viewing the Flash video results in concealed JavaScript being executed while the video is playing.

The video is hosted on a legitimate site. The threat exploits an authentication cookie of a currently logged-in user in order to send out the same link (for the Flash file) to users on the Friends list.
