Two of the World’s Largest Botnets May Be Connected

Rustock and Srizbi, two of the world’s biggest spam botnets, may be connected. Researchers have discovered that the two botnets share the same malware delivery method, a Trojan called Trojan.Exchange, which is activated when unsuspecting users click on malicious links in spam messages. Most of the spam the botnets send is of the fake headline variety (such as the recent Obama and Nuclear Disaster spams) and the fake video variety (this type usually tells the recipient they were caught on video in an embarrassing situation and invites them to click on a link to see for themselves).

Rustock is currently the biggest spammer on the net, with Srizbi a close second.
