Ubergeek Steve Gibson — of Gibson Research, publishers of one of the coolest pieces of software ever, the original SpinRight — was the victim of a distributed denial of service attack recently (in the vernacular, he “got DDOS’d”). This annoyed him, so he started digging.
While his actions in no way protect him from what the true hardcore hacking community could do (a fact he acknowledges completely), his account makes for pretty compelling reading even if you’ve only got a vague notion of how the Internet works (actually, his site includes some basic information on that, too). From a technical standpoint, it’s also pretty damned impressive.
