When I was an undergraduate in engineering school, I worked on side projects. They weren't exactly intended for the public good.
Kids, don't try this at home
One project involved building a long-range beam laser that we could shine down from the dorms and freak out the drunks stumbling home from frat parties. Another was perfecting a multi-stage bottle rocket we could launch from a stealthy launch platform in our dorm window, which would fly halfway across the quad before igniting the second stage and then strafing the campus security guards as they did their rounds.
The world was a different place in the late 1970s. Those stunts would have landed me and my fellow engineering students in an ocean of hot water, had they been attempted in this post-9/11 era. Back then, it was just lolz all around.
Granted the projects I did for degree requirements were academically sound (I did graduate with honors, after all). But the side projects, well, socially redeeming wasn't exactly a concept I was able to fully integrate into my psyche until well after I graduated.
His mother should be very proud
Julian decided, what with all the lists of personal information being released to the public by the likes of Anonymous, Wikileaks, AntiSec, and LulzSec, individuals might be worried that their information might now be out "in the wild."
So Julian's been curating the released data. He's built a database containing all the email addresses (over 1.4 million addresses, including the Booz Allen Hamiliton breach).
All you have to do is go over to HackNotifier.com. Enter your email address (which he promises me he's not capturing), and the site will tell you if your email address is in any publicly available leaked database.
Now, Julian's not all altruism and spice and everything nice. He's got a neat, little profit engine built into his database, which is the "notifier" portion of the site. For $9.99 a year, you can register with HackNotifier and if any new breaches do have your information, he'll let you know.
The necessary cautionary words
Obviously, all I have is Julian's word that he's not capturing email addresses for future nefarious purposes, but in my conversations with him, he seems like a good kid. He's built a useful service and, if he's lucky, he might also make a few bucks off it.
Me? Well, I probably shouldn't say any more about what I was up to when I was his age, but it sure as heck wasn't public service.
