On November 22, T-Mobile, one of the biggest telecommunications firms, revealed that a security breach might have affected the personal data of its prepaid customers. Compromised data includes customer names, billing addresses, phone numbers, account numbers, rate plans, and plan features.
The cybersecurity team at T-Mobile discovered the breach and immediately stopped a malicious virus from further accessing data, then notified law enforcement. Fortunately, social security numbers, passwords, and financial data were not affected in the breach. All affected users were notified by SMS and were advised to change their passwords and pin codes.
This is not the first time T-Mobile reported a data breach. In August 2018, there was a massive data breach that affected two million personal records of US customers.
