Yay:

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC 
Trojan.Win32.Syndicasec Stage Two traffic"; flow:to_server,established; 
content:"POST"; http_method; content:"HTTP/1.0"; 
content:"cstype=server|26|authname="; http_uri; metadata:policy 
balanced-ips drop, policy security-ips drop, service http; 
reference:url,http://www.welivesecurity.com/2013/05/23/syndicasec-in-the-sin-bin; 
classtype:trojan-activity; sid:10000072; rev:1;)

And a question...would it make sense to add http_header; after 
content:"HTTP/1.0";?  Thanks all.

James
