Thanks James, I ran the samples and got a slightly better content match:

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC Fort Disco Registration outbound connection"; 
flow:to_server,established; content:"/cmd.php"; http_uri; content:"User-Agent|3A 20|Mozilla/4.0 (compatible|3B| 
Synapse)"; fast_pattern:only; http_header; metadata:policy balanced-ips drop, policy security-ips drop, ruleset 
community, service http; reference:url,www.net-security.org/secworld.php?id=15370; classtype:trojan-activity; 
sid:27599; rev:1;)
