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.
