"A new distributed denial of service tool has been discovered in the wild and is spreading, according to Internet Security Systems Inc.'s X-Force service. Reports of up to 400 hosts running the "Trinity v3" agent have been reported, including 50 compromised IRC (Internet Relay Chat) hosts, said Chris Rouland, director of X-Force. Rouland said no high-profile commerce sites have been reported down yet, but "one or two" universities have been affected."

"Using chat for attacks is a trend; chat in general is Internet-risky behavior," Rouland said. "It's fairly anonymous for an attacker to go onto a chat system and launch attacks, and anyone who can access this new chat room that Trinity v3 creates can launch further attacks."

"Trinity v3 so far has been seen on Linux machines. The binary code is installed on a Linux server at /usr/lib/idle.so. When idle.so is launched, it connects to one of 11 Undernet IRC servers and sets a nickname for itself (which combines the first six letters of the host with three random digits). The code then joins the chat room #b3eblebr0x. Once there, the code waits for commands to attack either individual Trinity agents or to attack all agents on the channel."
