When Spammers Hit Back

Wired.com has a great article on the work conducted by Blue Security. However, Blue Security has put down its weapon and left the ring. But those guys can remember that they did make a difference and presented an outside-the-box method of fighting spam.

Perhaps one day, the Can-Spam Act can be used to fight the real spam problem, at this point it is just a sheet of paper in my view. Used against real companies that make mistakes, it isn't stopping PharmaMaster and others like him.

------------------------------

Starting May 2, a spammer known as PharmaMaster used a massive network of zombie computers to flood Blue Security's database servers with fake traffic and hijacked a little-known Cisco Systems router feature known as "blackhole filtering" to block anyone outside Israel from accessing Blue Security's homepage.

Blogging software provider Movable Type's hosted service, TypePad, also fell victim to PharmaMaster's bot network, after Blue Security realized that no one could reach its homepage and posted a message to its users on its old blog. Thirty minutes later, PharmaMaster started an attack that brought down thousands of blogs.
