I am pen-testing a Windows webserver, and a port scan reveals ALL tcp ports open. hping also confirms that a SA is returned for any S packets sent to any port I try. I can connect via netcat any of the ports, and send data, but nothing is returned. In order to verify services, I am required to connect and check for a banner or send appropriate protocol commands to elicit a response. Has anyone seen this, or have any idea of what this is?
I seem to recall that milky ways FW behaved that way. It has been a long time so maybe someone else can confirm. Then there are ways for a make believe windows server to do that too. Maybe a honeypot or even a portsentry like software written to listen on all ports in services. (But not respond per each ports proto requirements.)
