AT&T Says Customer Data Accessed To Unlock Smartphones

itwbennett writes: Personal information, including Social Security numbers and call records, was accessed for an unknown number of AT&T Mobility customers by people outside of the company, AT&T has confirmed. The breach took place between April 9-21, but was only disclosed this week in a filing with California regulators. While AT&T wouldn't say how many customers were affected, state law requires such disclosures if an incident affects at least 500 customers in California.
