Internet Landfill: McColo Corporation

Brian Krebs has turned his sights on another Internet Landfill, this time the McColo Corporation. Today his column is titled: Major Source of Online Scams and Spams Knocked Offline. Later this morning, the Washington Post ran a longer story on the topic, Major Source of Internet Spam Yanked Offline: Web Hosting Firm Shuttered After Connection to Spammers is Exposed He mentions in the column that he has been researching McColo for several months, and that when he contacted McColo's upstream providers, Global Crossings and Hurricane Electric, that something interesting happened.

Hurricane Electric's Benny Ng told Krebs:

"We looked into it a bit, saw the size and scope of the problem you were reporting and said 'Holy cow! Within the hour we had terminated all of our connections to them."

Although Global Crossings declined to give Krebs a comment, apparently Krebs has once more accomplished what the entire rest of the security world has been unable to do -- removing another Internet Landfill from the world wide web.

I coined the term "Internet Landfill" in a presentation regarding Krebs earlier amazing work almost single-handedly removing Intercage from the Internet. I explained it by saying:

Every house has a trash can, and every business has a dumpster. There's a little garbage anywhere you look. But when someone buys the land in your neighborhood and decides to make it a garbage dump, or a landfill, usually the citizens in that neighborhood protest. Some places on the Internet, such as Intercage, exist solely to store filth, malware, and crime. Those places should be treated like "Internet Landfills", and their neighbors should rise up and protest their presence in their neighborhood.

In case anyone has a question about what type of organization McColo is, here is a little fact-finding adventure, using the excellent Reverse IP Tools from, and the ASN information from CIDR-Report.

McColo's Autonomous System Number is AS26780.

At this time, Hurricane Electric is no longer listed as an upstream, but Global Crossing *IS* still showing a listing, connecting AS3549 (GBLX) to AS26780(MCCOLO).

The Netblocks currently published as being at McColo are:

All their other netblocks are strangely missing.


All of McColo's "Business" webpages were on the server That IP resolved, .com, .info, .net, and .org.

Is this the end of McColo? Probably not. Like the Intercage fiasco, we will probably see loud and public outcries of discrimination followed by mournful apologies and promises to do better, each accompanied with a short-lived resurrection, which will terminate again as soon as the new providers understand what sort of filth they are accomodating, and how the Neighbors (that's you and I, folks) feel about having this trash on OUR Internet.

Trying a new setting. After turning on comments, I got about 20-30 comments per day that were all link spam. Sorry to require login, but the spam was too much.
