A few weeks ago I published a short post on the demise of Atrivo (aka Intercage). Today Washington Post technology columnist Brian Krebs brings word that McColo Corp., a Northern California hosting firm that had been identified by the computer security community as home base for machines responsible for coordinating the sending of roughly 75 percent of all spam each day, has been taken offline.

The volume of junk e-mail sent worldwide dropped drastically today after a Web hosting firm identified by the computer security community as a major host of organizations allegedy engaged in spam activity was taken offline, according to security firms that monitor spam distribution online.
While its gleaming, state-of-the-art, 30-story office tower in downtown San Jose, Calif., hardly looks like the staging ground for what could be called a full-scale cyber crime offensive, security experts have found that a relatively small firm at that location is home to servers that serve as a gateway for a significant portion of the world’s junk e-mail.
The servers are operated by McColo Corp., which these experts say has emerged as a major U.S. hosting service for international firms and syndicates that are involved in everything from the remote management of millions of compromised computers to the sale of counterfeit pharmaceuticals and designer goods, fake security products and child pornography via email.
But the company’s web site was not accessible today, when two Internet providers cut off MoColo’s connectivity to the Internet, security experts said. Immediately after McColo was unplugged, security companies charted a precipitous drop in spam volumes worldwide. E-mail security firm IronPort said spam levels fell by roughly 66 percent as of Tuesday evening.
Spamcop.net, another spam watch dog, found a similar decline, from about 40 spam e-mails per second to around 10 per second. Read the rest…
