Well, it was a long Sunday. I was planning on going and hitting some balls on the golf course, but no, instead I spent the better part of the day dealing with a DDoS attack. Before it was completely killed 73 IPs were used to perform a flood of GET requests against sla.ckers.org. Thankfully we were able to thwart the attack by writing some tricky software to detect the attack and firewall it. But it was still the better part of a day dealing with it.

The end result was we found the attacker (the owner of www.au-p2p.info who apparently was made fun of at some point a year ago on the board). When pride goes too far, eesh! More on this user here. Cyberhacker665 is in at least some way affiliated with or owns evilzone.org. The attacker did a vanity search for himself before initiating the attack. The original IP was tracked back to the attacker’s ISP, who was sent an abuse email and now the user is offline for the time being. We effectively DoSed the DDoSer. It’s too bad, I had long forgotten about that post - apparently he hasn’t.

This wasn’t the first high volume traffic incident we’ve received (we’ve been slashdotted several times, and reached the front page of Digg and Reddit as well) and we get tons of attacks per day. But this was probably one of the worst. Just another day on ckers.org… Golfing would have been better use of a Sunday, even if I suck at it.
