DoS attacks getting scary, CERT warns

Author: JT Smith

The Register: "The mechanisms for controlling large numbers of compromised boxes have also
changed, said Houle, becoming vastly more sophisticated since DDoS attacks
began in 1999. Attackers increasingly use IRC -- the Internet's chat room systems
-- to direct attacks, sometimes using domain name records as a kind of dead drop
for directing their agents to a particular IRC server.

More disturbing to network operators, attackers have taking over the machines that
route and direct the flow of Internet traffic, to use them as weapons."
