Nathan,

Thanks, this is how I added it:

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"EXPLOIT-KIT Rawin exploit kit outbound java retrieval"; 
flow:to_server,established; content:".php?b="; http_uri; content:"&v=1."; distance:0; http_uri; 
pcre:"/\.php\?b=[A-F0-9]+&v=1\./U"; metadata:policy balanced-ips drop, policy security-ips drop, ruleset community, 
service http; classtype:trojan-activity; sid:26985; rev:1;)
