There is a new book out entitled "Fatal System Error", which, among other things, takes an in depth look at the Mob and its influence over the Internet from the United States to Costa Rica to Russia.
The first half of the book tells the story of Barrett Lyon, who as founder of Prolexic Technologies seven years ago applied his skills to protecting customers, a number being in the
online gambling industry, against denial-of-service (DDoS) attack from extortionists who were bringing down their sites and demanding tens of thousands of dollars to go away. Eventually, a young
Russian cybercriminal named Ivan Maksakov was brought to justice thanks mostly to Lyon's efforts.
I just love any kind of mob stories.
