Hey all. Here's the rule: alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"MALWARE-CNC Ortega Rootkit outbound connection - search.namequery.com"; flow:to_server,established; content:" search.namequery.com|0D 0A|"; fast_pattern:only; http_header; content:"|0D 0A|TagId: "; depth:9; offset:15; metadata:impact_flag red, policy balanced-ips drop, policy security-ips drop, ruleset community, service http; reference:url,www.blackhat.com/presentations/bh-usa-09/ORTEGA/BHUSA09-Ortega-DeactivateRootkit-PAPER.pdf; classtype:trojan-activity; sid:26287; rev:1;) Any additional info on this? You didn't hear this from me, but this fires on Fujitsu Q550 running Windows 7 Professional x86 out of the box :) James ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
