Would this be more valuable as: alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"COMMUNITY INDICATOR-COMPROMISE /rebots.php HTTP request in URI"; flow:established,to_server; content:"/rebots.php"; http_uri; fast_pattern:only; reference:url,http://labs.sucuri.net/db/malware/mwjs-include-rebots; sid:x; rev:1;) Cheers, NathanThanks Nathan...as usual you're cleaning up my messes...the above looks much better than mine :)
We wouldn't put this in INDICATOR-COMPROMISE. I'd probably put this in SPECIFIC-THREATS for now. INDICATOR-COMPROMISE is saved for things things that indicate there is a successful compromise. alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"SPECIFIC-THREATS Possible malicious redirect - rebots.php"; flow:to_server,established; content:"/rebots.php"; fast_pattern:only; http_uri; metadata:policy balanced-ips drop, policy security-ips drop, service http; reference:url,labs.sucuri.net/db/malware/mwjs-include-rebots; classtype:misc-activity; sid:24017; rev:1;) I've added it for release. Also, because I know Nathan will ask -- The Community ruleset tag is coming, it just got pushed back with the massive ClamAV transition that happened last quarter.
