Threat ID 39341 - Metasploit Windows Meterpreter Reverse HTTPS Detection

Hi,

Does anyone know if this signature is expected to trigger based on *unencrypted* SSL traffic, or on a Meterpreter session in a decrypted session?

Obviously the former would be useful (to say the least) - but assume it will be trying to detect based on aspects of the certifcate being used (assuming no custom cert has been injected into the stage(r)) as that would be the most likely visible trait.

We've done some testing and never see it fire - we wouldn't expect it to be 100% reliable in either case, but knowing the conditions it may trigger under would be useful to gauge it's protection capabilities.

The signature is based off clear-text of the actual 'reverse https tool' payload being transferred over the wire.

If the tool is transferred using HTTPS then SSL Decryption should take place before-hand for the IPS engine to pattern-match with this signature.
