My friend and I play a game every once in a while. We hack people & split the earns. I guess I just do the social engineering, I simply convince them to click a link to a .zip file with a trojan (and keylogger) in it, he configured it and everything. I'd like to learn more about how it's done or the components of making a trojan. I'm not asking for a quick way to do this, or pestering my friend to teach me, I want to learn how to make one myself. I'm willing to put time into learning. I'd just like someone to point me in the right direction, maybe give me some links or explain how a trojan works for starts. Thanks if you decide to help.
