3 pointsIt's a mindset. You hack to learn, you don't learn to hack.
2 pointsHrmph. DDoS isn't "hacking" and it's lame. Botnets can be interesting, but not for what you want to do (malicious activity). You'd be better off spending your time on better ventures. IE - "real hacking". There's a ton of ways you can get involved which don't involve destruction and disturbance of services. Hardware hacking, System & network security, etc.
