Didn't have a ton to work with:

alert tcp $EXTERNAL_NET $HTTP_PORTS -> $HOME_NET any (msg:"MALWARE-CNC 
BitBot Idle C2 response"; flow:from_server,established; file_data; 
content:"<|5c||5c||5c|>IDLE<|5c||5c||5c|>"; depth:18; metadata:policy 
balanced-ips drop, policy security-ips drop, service http, ruleset 
community; 
reference:url,http://blogs.mcafee.com/mcafee-labs/delving-deeply-into-a-bitcoin-botnet; 
classtype:trojan-activity; sid:10000074; rev:1;)

Also, anyone know if there's a....server response to client much like 
http_client_body?  Just curious..thanks all.

James
