The Register reports a correlation between Sobig and DDOS attacks on Anti-Spam sites:
Earlier this week two anti-spam services, Monkeys.com and the Compu.Net "block list", announced their closure due to DDoS attacks, and other attempts by spammers to make their operation as difficult as possible. Their closure follows an earlier decision to discontinue the popular if controversial SPEWS block list (which was run by Osirusoft.com) for similar reasons (see postings to news.admin.net-abuse.email for more info).
Linford tells The Reg that Spamhaus has been under constant "extremely heavy" DDoS attack since early July. He believes the attack against his site and others originates from Windows machines infected with the Sobig worm, controlled by spammers over IRC networks.
Looks like semi-open war is breaking out on this front - and available bandwidth is going to end up being the collateral damage.
