T-Mobile today disclosed a data breach affecting tens of millions of customer accounts, its second major data exposure in as many years. In a filing with federal regulators, T-Mobile said an investigation determined that someone abused its systems to harvest subscriber data tied to approximately 37 million current customer accounts.
The U.S. Department of Justice (DOJ) said today it seized the website and user database for RaidForums, an extremely popular English-language cybercrime forum that sold access to more than 10 billion consumer records stolen in some of the world’s largest data breaches since 2015. The DOJ also charged the alleged administrator of RaidForums — 21-year-old Diogo Santos Coelho, of Portugal — with six criminal counts, including conspiracy, access device fraud and aggravated identity theft.
T-Mobile warned Monday that a data breach has exposed the names, date of birth, Social Security number and driver’s license/ID information of more than 40 million current, former or prospective customers. The acknowledgment came less than 48 hours after millions of the stolen T-Mobile customer records went up for sale in the cybercrime underground.
T-Mobile disclosed last week that some 15 million customers had their Social Security numbers and other personal data stolen thanks to a breach at Experian, the largest of the big American consumer credit bureaus. But this actually wasn’t the first time that a hacking incident at Experian exposed sensitive T-Mobile customer data, and that previous breach may hold important clues about what went wrong more recently.
Kicking off National Cybersecurity Month with a bang, credit bureau and consumer data broker Experian North America disclosed Thursday that a breach of its computer systems exposed approximately 15 million Social Security numbers and other data on people who applied for financing from wireless provider T-Mobile USA Inc.
