[QUOTE="csun_mizzou, post: 743463, member: 73134"] Here is some more info on how it was detected. The Snort rule that the traffic matching on is as follows: alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC User-Agent known malicious user-agent string RookIE/1.0"; flow:to_server,established; content:"User-Agent|3A| RookIE/1.0|0D 0A|"; fast_pattern:only; http_header:; metadata:impact_flag red, policy balanced-ips drop, policy security-ips drop, service http; reference:url,snort.org/rule_docs/1-18388; classtype:trojan-activity; sid:18388; rev:11; gid:1; ) • The traffic is coming from campus IP space and going to an external IP • The user-agent contains the string "RookIE/1.0" [/QUOTE]
