This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
I haven't followed it, but did a quick search after your post. My take on these guys has always been this; what a huge waste of talent. We need people with these skills doing white-hat work and preparing to defend us against the Chinese government hackers, not wasting time harvesting email addresses for bragging rights. There is a right way and a wrong way to do penetration and vulnerability testing. The right way benefits everyone, the wrong way only benefits the hacker.
IMHO, this guy is a complete loser.
