(Bloomberg) -- T-Mobile US Inc. said Friday that a hacker gained access to limited information contained in prepaid accounts.
The hack, which was discovered in early November, affected less than 1.5% of T-Mobile customers and was quickly shut down by the carrier’s cybersecurity team, according to company statements. No financial data such as credit card information or Social Security numbers were included in the hack, and no passwords were compromised, the company said.
The information that was accessed included names, billing addresses, phone numbers and account numbers, according to a notification sent to customers.
T-Mobile said it was nearly done notifying customers affected by the breach. The company said it reported the “malicious, unauthorized access” to authorities.
