iptables -I INPUT -p udp -m string --algo bm --string 'physics_select' -j
DROPRequires: ipt_string firewall module.

Thats the IPTables command that fully blocks this attack. Feel free to use
it on your own servers. The attack was generating from a clan called "MIA"
they run a Jailbreak server. They also seem to be attacking anyone who runs
a map with "MIA" in the name from what I can gather. Hopefully this will
help you guys out. Also feel free to block more commands with that as well.

For our Windows counter parts I have no idea what your going to use.
