I was wondering why I was getting so much less spam since last two or three days. Now I know the answer. This is a great example of journalism - as the Washington Post 'Security Fix' Blogger Brian managed to shut down McColo, a US-based hosting provider responsible for 75% worldwide spam. From the blog post:
A U.S. based Web hosting firm that security experts say was responsible for facilitating more than 75 percent of the junk e-mail blasted out each day globally has been knocked offline following reports from Security Fix on evidence gathered about suspicious activity emanating from the network.
For the past four months, Security Fix has been gathering data from the security industry about McColo Corp., a San Jose, Calif., based Web hosting service whose client list experts say includes some of the most disreputable cyber-criminal gangs in business today.
