Under Armour notified employees last week about a data breach that may have exposed their names, Social Security numbers and salary information. Baltimore-based Under Armour told employees in an email message that an unencrypted thumb drive containing employee payroll information was lost in the U.S. mail on or about April 12 by its auditing firm, PricewaterhouseCoopers. The thumb drive was sent by mail in connection with a recent audit, the memo said.
