He provided details and helped coordinate with multinational law enforcement groups which resulted in the capture of Ivan Maksakov, Alexander Petrov, and Denis Stepanov [5]. The three men were at the heart of an extortion ring which was extorting money from banks, Internet casinos, and other web based businesses.
