Could someone fill me in a bit on the risks of tunneling over SMTP, HTTP, etc. What are the capabilities of this sort of attack? How is it accomplished (in general terms).
You take a stream of IP packets. You encapsulate them in what appears to be a "normal" XXXP stream. You have something at the other end - an IP "modem" - that translates them back into an IP stream. You can do anything you want over this encapsulated IP stream. Slowly, usually. -- Joe Yao jsdy () cospo osis gov - Joseph S. D.
