The FBI has issued a warning about a cautionary incident.
A 31-year-old Californian man was arrested for infecting computers with a backdoor trojan. He was sending the trojan via e-mail to people he had friended online. The malware was typically made to look like a video file. In reality it dropped a backdoor that gave the attacker control of the victim's PC. Then the attacker searched for explicit pictures from victims' computers. If he found any, he downloaded them, and used the images in an attempt to extort more pictures and videos from them. Many of the victims were teenage girls.
Now FBI is trying to find more on the case. The hacker used a variety of screen names and e-mail addresses, which are listed below. If you have seen them online and have information that might help in the case, please contact the investigators working on the case.
