Spam in 2008

Tuesday, March 3rd, 2009

The general consensus on the spam situation is that it's just going to keep getting worse until an updated mail protocol is adopted. I've accepted this and can deal with it; as the spammers come out with new tricks, new methods for dealing with those tricks come out.

I was surprised to see that overall in 2008 the amount of spam aimed at Harley actually went down!

spam trend for 2008

There was a pretty big reduction near the middle of November that I think can be attributed to the shutdown of the internet service provider McColo. We only saw a small decrease, but according to that article right after they were disconnected a 60% decrease in spam was detected! I can't believe if one ISP is responsible for that much spam, why weren't they shutdown sooner?

Mccolo wasn't doing anything technically illegal under Safe Harbor provisions. Their upstream providers shut them down after realizing the volume of complaints. Also, the spam was primarily from botnets with the C&C servers on McColo.

Illegal no, but probably in violation of their peering agreement with Hurricane Electric.

Out of curiosity, do you do any sort of pen testing on the Harley network?
