I read an interesting article by Raphael Mudge, creator of Cobalt Strike. He explains how one could download the Cobalt Strike program and crack it. You can inject your own evil code into the install. Then you can post your results up on some site as a cracked version. Read all the details on his blog.
Part of the reason why this is possible is that he uses the Sleep scripting language in his solution. So you can modify his Sleep scripts to do some of your own work. I like how the guy freely comes out and explains how to do it. His software is, after all, a tool to help penetration testers. I do understand why people might want to crack his software. Prices start at $2500 per year per user. And that is the discounted price!
