I haven't seem a bot using dns covert channel, so i've tried to create one.

client poorly written in assembly 32 bits and server poorly written in
perl. given a list of public domains extracted from
http://freedns.afraid.org/ the bot tries to contact his master and
after a very simple challenge (xor/sub/add) the master can ask for
system version, submit files, and code execution (maximum of 399
bytes) - with only dns packets.

to test it, need to create a subdomain at freedns.afraid and a machine
listening on port 53 to where the server answer requests.
