Thief Stole Payroll Data for Thousands of Facebook Employees

Personal banking information for tens of thousands of Facebook Inc. workers in the U.S. was compromised last month when a thief stole several corporate hard drives from an employee’s car.

The hard drives, which were unencrypted, included payroll data like employee names, bank account numbers and the last four digits of employees’ social security numbers, according to an email Facebook shared with staff Friday morning. The drives also included compensation information, including salaries, bonus amounts, and some equity details.
