I started out laughing about this a bit. Then I read this.

The spammer's counterattack generated so much Internet traffic that it also affected other sites, including Six Apart Ltd., a San Francisco-based company that runs millions of Web sites through its TypePad and LiveJournal blogging services. The attack also shut down operations for roughly 12 hours at Tucows Inc., a Toronto-based Internet services company that helped manage Blue Security's site.

Tucows chief executive Elliot Noss called the attack "by far the largest the company had ever seen," and said that only a handful of companies have the infrastructure in place to withstand such an assault, much less a more powerful one.

In the Fight Against Spam E-Mail, Goliath Wins Again

Eran Reshef had an idea in the battle against spam e-mail that seemed to be working: he fought spam with spam. Today, he'll give up the fight.

Reshef's Silicon Valley company, Blue Security Inc., simply asked the spammers to stop sending junk e-mail to his clients. But because those sort of requests tend to be ignored, Blue Security took them to a new level: it bombarded the spammers with requests from all 522,000 of its customers at the same time.

That led to a flood of Internet traffic so heavy that it disrupted the spammers' ability to send e-mails to other victims -- a crippling effect that caused a handful of known spammers to comply with the requests.

Then, earlier this month, a Russia-based spammer counterattacked, Reshef said. Using tens of thousands of hijacked computers, the spammer flooded Blue Security with so much Internet traffic that it blocked legitimate visitors from going to Bluesecurity.com, as well as to other Web sites. The spammer also sent another message: Cease operations or Blue Security customers will soon find themselves targeted with virus-filled attacks.

Today, Reshef will wave a virtual white flag and surrender. The company will shut down this morning and its Web site will display a message informing its customers about the closure.

"It's clear to us that [quitting] would be the only thing to prevent a full-scale cyber-war that we just don't have the authority to start," Reshef said. "Our users never signed up for this kind of thing."
