“A superb, insider tour of the dark Internet that lies below "the whitewashed, commercialized" world of the Web. Kevin Poulsen is one of the very few people who understands the territory: the scammers, the scammers of the scammers, and the law enforcement officers trying to catch them. KINGPIN describes a parallel business world, including "the underground's first hostile takeover," where characters who call themselves names like DarkCyd and Matrix and Ghost23 battle for control of digital scams. It is a fascinating, scary ride. - Review”

About the Book:
In a previous life, Poulsen served five years in prison for hacking. So the Wired senior editor and "Threat Level" blogger knows intimately the terrain he explores in this page-turning tale of the criminal exploits of a hacker of breathtaking ambition, Max Butler, who stole access to 1.8 million credit card accounts. Poulsen understands both the hows of hacking, which he explains clearly, as well as the whys, which include, but also can transcend, mere profit. Accordingly, his understanding of the hacking culture, and his extensive interviews with Butler, translates into a fascinating depiction of a cybercriminal underworld frightening in its complexity and its potential for harm, and a society shockingly vulnerable to cybercrime. The personalities, feuds, double dealing, and scams of the hackers are just one half of this lively story. The other half, told with equal verve, is law enforcement's efforts to find and convict Butler and his accomplices. (Butler is now serving a 13-year sentence and owes .5 million in restitution.) Poulsen renders the hacker world with such virtual reality that readers will have difficulty logging off until the very end.
