Re: Why attacker install irc after hacking?

[xun dong <xundong () cs york ac uk>]

IRC is mainly served as the Command and Control(C&C) Tool after hacking.
For example the hacker can send the command such as starting keylogger
or initiate a email spam via the irc communication channel.

A large number of botnets also use the irc as the communication channels
as well. So if you see the irc installed after hacking, it is very
likely your PC is part of a botnet.

I think another reason IRC is choosen is because it is widely used, and
the hacker is very familiar with it already.
