Well I just want to add my two cents here, not by technical, but all good advice isn't always technical . Anyway, I do happen to know that Revelation has written some text files a few years back. I haven't seen any up to date information written by him, so just to point out reading out dated guides and tutorials isn't really going to help you, if you're not looking to read up on the history of hacking, and what was useful back then. The best way to really learn is to pick up a copy of Hacking Exposed (http://www.hackingexposed.com) or some security book like Security Complete (http://www.sybex.com) and read it to a point where you have a pretty firm grip on what you're doing. Then, you'd be sure to know what is enough to keep the negative things out, like worms and hackers.
