We were just hit by the Ramen Worm
see http://members.home.net/dtmartin24/ramen_worm.txt

This is my attempt for a couple of rules. My tcpdump data isn't long
enough to match the content, actually I only have "GE" but I know it's
a GET - actually from "lynx -source http://attacker:27374"

alert tcp $HOME_NET 27374 -> !$HOME_NET any (msg:"Ramen Worm server active
on network";flags:PA;content:"GET ")
alert tcp $HOME_NET any -> !$HOME_NET 27374 (msg:"Ramen Worm
downloading";flags:PA;content:"GET ")
