The 10 Biggest Data Breaches of 2014 (So Far)


P.F. Chang's China Bistro

Scottsdale, Ariz.-based restaurant chain P.F. Chang's is still investigating the extent of its data security breach. The Secret Service notified the company in June that attackers struck the payment systems used at its 211 restaurant locations. The attack may have exposed thousands of cards between March and May of this year, according to Brian Krebs, a reporter who investigates credit card theft and organized cybercrime and noted a flood of new credit card data in underground hacking forums, where stolen information is sold.

In addition to obtaining digital forensics services, P.F. Chang's CEO Rick Federico ordered all restaurants to use manual credit card devices. The firm issued an update in July, announcing that it recently added "encryption-enabled terminals" at all of its locations, while its investigation continues.
