Slow Thursday:

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC 
Trojan.Win32.Gapz C2 traffic"; flow:to_server,established; 
content:"|2f|images|2f|gx.php"; http_uri; metadata:policy balanced-ips 
drop, policy security-ips drop, service http; 
reference:url,http://bartblaze.blogspot.com/2013/05/another-skype-worm.html; 
classtype:trojan-activity; sid:10000071; rev:1;)

Could add the UA that's in the strings of the malware executable from 
the pastbin link I guess to tighten it up.
