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.

``Code Caves'' won't do you any good. It'll make your code more conspicuous. You'll need to give more details on what you're trying to accomplish. Are you trying to hide it from a skilled reverse engineer? Doubtful you'll be able to, your code will stand out, and if you do manage to integrate it with the application, there are dynamic means for detecting it, unless your code isn't malicious by itself, and yet it can end up compromising someone's machine (you'd be surprised by the vulnerabilities found in common software - is there a difference between a (security) bug the author knows about, but doesn't disclose it and one they have no knowledge of?). Are you trying to hide it from automatic tools? You'll have a much higher chance of success then.
