Notorious Spam-Linked Web Hosting Service Goes Offline
McColo, a Web hosting firm believed to be responsible for hosting roughly three-quarters of the world's spam, goes offline. Two of the firm's primary ISPs reportedly cut ties with the company after receiving evidence of McColo's ties to botnets and cyber-crooks.A Web hosting firm reportedly responsible for hosting roughly 75 percent of the world's spam went offline Nov. 11 after its primary Internet providers cut the company off. According to the 'Security Fix' blog in the Washington Post, McColo's two main ISPs, Global Crossing and Hurricane Electric, terminated service after getting reports from Security Fix about McColo's activities. Security Fix said it studied the company for four months before reporting the issue.
Security researchers have accused McColo of hosting the command-and-control servers for a number of well-known botnets, including Rustock and Srizbi. In a report on McColo featured on hostexploit.com, researchers predicted if McColo were depeered, worldwide spam output would likely be cut in half. Hostexploit.com published a similar report on ISP Atrivo earlier in 2008.
