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
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.
