Record Breaking Comment Spam Attack!

Posted by todd at 1:58 AM on June 23, 2007

I noticed my server being a little sluggish today, and when I looked at my log files was blown away. 880,000 plus attempts to deliver comment spam to this site in a 13 hour period. At some points in the day I was seeing as many as 28 attempts a second.

All of these attempts were coming from 32 IP’s from a broadband provider in Canada. By adding some rules to the firewall I was able to minimize the impact they were having.

MovableType did a good job handling the attack but my MySQL database grew to record proportions and I had to delete the junk comment folder a couple of times.

There really has to be a better way. I wonder how much of my bandwidth these people burned up today.

    I have found the Bad Behavior and Akismet plugins to have stopped most of my spam comments.

    The good thing about Bad Behavior is that it blocks the actual http request, so it doesn’t use the bandwidth.
