In this disquieting cyber thriller, Joseph Menn takes readers into the murky hacker underground, traveling the globe from San Francisco to Costa Rica and London to Russia. His guides are California surfer and computer whiz Barrett Lyon and a fearless British high-tech agent. Through these heroes, Menn shows the evolution of cyber-crime from small-time thieving to sophisticated, organized gangs, who began by attacking corporate websites but increasingly steal financial data from consumers and defense secrets from governments. Using unprecedented access to Mob businesses and Russian officials, the book reveals how top criminals earned protection from the Russian government.

Fatal System Error penetrates both the Russian cyber-mob and La Cosa Nostra as the two fight over the Internet?s massive spoils. The cloak-and-dagger adventure shows why cyber-crime is much worse than you thought?and why the Internet might not survive.
