HTTPort

This can be used to bypass the HTTP proxy. With the HTTPort, some services can be used behind the HTTP proxy. These servers include e-mail, IRC, news, ICQ, AIM, FTP, and any SOCKS-capable software. The main reason for this is for the user to be able to set up Internet software such that it considers the PC that is to be used. HTTPort uses a method called tunneling to intercepts connection from this software and run this connection through the proxy. Setting up the software with the HTTP port can be done using any of these two ways.

If the software uses a small range of fixed port or a single port with a single or small range of fixed servers, the software can be used to connect to some.server.com:some_port. New HTTPort mapping has to be created with any local port (preferably above 1023), remote server of some.server.com, and remote port of some port. The software should be pointed to 127.0.0.1: mapped_local_port as if it was the original server it needed.

If SOCKS4 proxy can be used to connect the software, the software should be pointed to 127.0.0.1:1080, which is a built-in HTTPort SOCKS4 server.

HTTPort makes it possible to open the client side of a TCP/IP connection and provide it to any software. “Client” means that HTTPort may not be used for Trojans, like NetBus or BackOrifice, because HTTPort cannot make a listening server side of a TCP/IP connection available for connection from the outside, which could possibly be exploited by Trojans. This, in turn, means that HTTPort may be utilized by client type software only, not server type. “Any software” indicates that any other software may use the same technique that HTTPort does to perform exactly the same thing. Moreover, the client-side of the malicious software may use plain HTTP to access a remote malicious server.
