hello list, For the last couple of months i've been researching some peculiarites of the transport layer protocol which deflowered into a project of mine. The name is kless, and its goal is to be able to communicate using transport layer protocols (tcp/udp) without opening any ports ( at least on the server- side ) and still be able to talk transparently to a client. Even if this topic and probly the same technique are already known and a few tools already exists i've written a paper which explains the whole concept and further more extends it. The project also explains a way for you to kill udp sockets, even if you do- nt have anything todo with the connection and a few other tricks. The text wi- ll culminate into the coding of a remote portless shell and some other tools for explaning purpose.. Hope you guys enjoy it, comments/flames/feedbacks are expected... [kless paper + proof of concept code + few other tools ] http://setuid.violating.us/releases/kless.tar.gz setuid at violating dot us | s3tuid at violating dot us
