Anthony Scott Clark of Oregon is facing up to 10 years in prison after he pled guilty to charges of performing a distributed denial of service attack on eBay in 2003. Clark, 21, has admitted that he and unnamed associates coordinated a network of 20,000 hijacked computers to launch DDOS attacks against eBay.com. Clark used this "botnet" to do the attacks, which had been assembled using a worm program that exploited RPC-DCOM vulnerabilities in Windows.
The computers were then directed to a password protected Internet Relay Chat (IRC) server where they connected, logged in and waited for instructions. Under Clark's control, the bots launched DDOS attacks at computers or computer networks connected to the Internet.
