Jeremy Hammond has been around for a while: http://en.wikipedia.org/wiki/Jeremy_Hammond

He created a whole site like Stripe's Capture the Flag back in 2003: http://en.wikipedia.org/wiki/HackThisSite

This part of his history is also sad:

Hammond attended the University of Illinois at Chicago on a full scholarship. In the spring of 2004, during his freshman year, he pointed out a security flaw on the computer science department’s website to department administrators, offering to fix it. For pointing out the flaw, Hammond was called before the department chair and ultimately banned from returning for his sophomore year.
