Trojan project

Greetings /prog/, I'm from a neighboring board.

I'm on the last phases of a trojan project. I'm having a hard time finding the best way of hiding my malicious executable within another executable. I assume the best way of doing that would involve assembly? "Code caves" seem to be what I'm looking for, though there doesn't seem to be much tutorials for it. Any advice? Thanks in advance.

So you basically encrypt what you say in the irc channel?

How would this stop someone simply greping the readable characters in your executeable; and using this info find where your irc server is located and shut it down?

Wouldn't a wiser approach be to 'r00t' someone else's server and run a ircd off that?
