The Rbot-GR is a worm series that exploits Microsoft security vulnerabilities to drop a backdoor Trojan horse program on vulnerable machinesand allows attackers to do whatever takes their fancy, as some variants of Rbot-GR are able to control webcam and microphones.

“If your computer is infected and you have a webcam plugged in, then everything you do in front of the computer can be seen, and everything you say can be recorded,” said Graham Cluley, senior technology consultant for Sophos. “It would be like having a regular web cam conversation except you wouldn’t know you’re taking part in it.”

Besides, the Trojan component of the worm will attempt to steal registration information for games and PayPal passwords from infected machines.

So far, Rbot-GR hasn’t particularly widespread.
