They should, yeah. But until then, I need to find a way to block the attack.

I've seen the same thing once. The attack rises CPU usage and causes lag
due to that. I only monitored while someone tried it, did cause some
harm but not too much. Perhaps the attacker was unexperienced at that time.
I guess Valve should look into this.

Hi.
For the past two days we've been hit by a skid trying to show off by taking our
servers down by sending them malformed packets and faked Source Engine Queries.
The messages look like this:http://pastie.org/private/kknzt5acoom8enl5bouwxq
We have tried blocking the attack using iptables without success. The length of
the packets varies, the source address and port varies, everything varies. What
can we do to stop this?
