Unusual firewall bypassing techniques, network and computer security.

Alice opened the door and found that it led into a small passage, not much larger than a rat-hole: she knelt down and looked along the passage into the loveliest garden you ever saw. How she longed to get out of that dark hall, and wander about among those beds of bright flowers and those cool fountains, but she could not even get her head through the doorway.

Cooking channels - is a set of two python scripts (CGI and client) allowing to build a communication channel over HTTP cookies.

The paper How to cook a covert channel [Hakin9 Pdf] originally released in the hakin9 magazine describes step by step how to implement a few covert channel concepts over HTTP cookies :
   o Control communication channel
   o As stealth as possible (don't care about latency or bandwith)
   o Backdoor oriented

The paper finally describes a funny second level caching method allowing to use HTTP proxy servers as intermediaries to build a communication channel thus having a way to communicate with a third party without having to reach the remote server for each data packet.
