I am not sure what is doing this, but I assume it is a software (or some kind of) firewall/hids, can anybody point me in the right direction? 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.
It seems like a kind of software firewall, like Zonealarm or Personal Sygate Firewall that it's responding to every port to check if it has to let the packets in or not. -- Jose Maria Lopez Hernandez Director Tecnico de bgSEC jkerouac () bgsec com bgSEC Seguridad y Consultoria de Sistemas Informaticos http://www.bgsec.com ESPAÑA The only people for me are the mad ones -- the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow Roman candles. -- Jack Kerouac, "On the Road" ------------------------------------------------------------------------------ Ethical Hacking at the InfoSec Institute.
