T-Mobile on Wednesday said criminals obtained the personal information of almost 49 million current, former, or prospective customers in the latest mega-hack of its servers.

The haul includes customers’ first and last names, date of birth, SSN, and driver’s license/ID information for 7.8 million current post-paid accounts, meaning accounts that are billed at the end of each billing cycle. The unknown hackers obtained the same data from more than 40 million records belonging to former or prospective customers who had previously applied for credit with T-Mobile.

Names, phone numbers, and account PINs for about 850,000 active T-Mobile prepaid customers were also stolen. T-Mobile said that “additional information” from an unspecified number of inactive prepaid accounts was also affected.
