T-Mobile Investigating Data Breach Affecting 37 Million Accounts

U.S. wireless carrier T-Mobile said it was investigating a data breach that may have exposed 37 million postpaid and prepaid accounts, and hinted at incurring significant costs related to the incident. It's the second major cyberattack in less than two years and comes months after the carrier agreed to upgrade its data security to settle a litigation related to a 2021 incident that compromised information of an estimated 76.6 million people.
