Some more information:

1) When the program is run, it install itself in registry for startup

2) It binds itself a _random_ listen TCP port and starts a proxy service.
The proxy code seems like a "normal" TCP connection forwarder, but I'm not
100% sure yet.

3) It sends the proxy port periodically, every 30 secs to cjdra.com with
the following url: http://cjdra.com/sd/PORT where PORT is the listening
port encoded as follows: for each port digit, do 46h + (39h - port), for
example: 1234 is NMLK. Probably the server is supposed to build some
database of the port/host information.

4) If the response HTTP page contains an ASCII string "upf:FILENAME"
somewhere, the program tries to fetch a file http://cjdra.com/FILENAME
and run it.
