Russian Hacker Drinkman Pleads Guilty in Largest Data Breach

Vladimir Drinkman, a Muscovite hacker, pleaded guilty in the biggest data-breach case in U.S. history, admitting he helped steal 160 million credit-card numbers.

Drinkman said Tuesday in federal court in Camden, New Jersey, that he conspired with four other men to pillage credit card numbers from Heartland Payment Systems Inc., 7-Eleven Inc., the Hannaford Bros. Co. grocery chain and at least 14 other companies from 2005 to 2012.
