I've been waiting to play with this tool since the presentation at Defcon. Tunneling TCP through well formed HTTP which decodes it on the other end back into TCP is a pretty handy option.
"What Does reDuh Do?
reDuh is actually a tool that can be used to create a TCP circuit through validly formed HTTP requests.
Essentially this means that if we can upload a JSP/PHP/ASP page on a server, we can connect to hosts behind that server trivially"
expect some more info soon.
