A security breach that hit AT&T in April was due to the actions of three employees and a service provider who accessed the personal information of account holders without permission, reports Government Security News. The breach led to the compromise of information including Social Security numbers and call records, but AT&T has not disclosed the number of affected users. The article says the stolen data may have “been accessed to unlock phones to sell on second-hand markets. The attackers hacked the AT&T database to get unlock codes in order to disconnect stolen phones from the network and reconnect to other mobile networks.” While the telecommunications company discovered the breach on May 19, AT&T’s letters to customers were just received this week. The company has filed notice with the California Attorney General's Office in compliance with the state’s data breach notification law.
