T-Mobile US said in a SEC filling that an additional 6 million customers were affected by its recent systems hack, taking the total to 54 million. The company previously reported that the breach affected 7.8 million current T-Mobile postpaid customer accounts that included first and last names, date of birth, SSN, and driver’s license/ID information was compromised.
The company said it is working on a forensic analysis and investigation into the cyber-attack against its systems while also taking a number of proactive steps to protect customers and others whose information may have been exposed.
T-Mobile said it has sent information to customers and other affected individuals and is providing support in various ways, including two years of free identity protection services with McAfee’s ID Theft Protection Service to any person who believes they may be affected. The firm recommends that all eligible T-Mobile customers sign up for free scam-blocking protection through Scam Shield, supporting customers with additional best practices and practical security steps like resetting PINs and passwords, and publishing a customer support webpage that includes information and access to these tools.
