T-Mobile Knew of Security Threat for Years, Court Documents Show

T-Mobile has been ordered to pay $33 million in an arbitration case. The ruling follows a major SIM swap attack on a customer. This incident occurred in early 2020.

The attack resulted in a massive theft of cryptocurrency. Court documents suggest T-Mobile knew about security vulnerabilities for years. The case highlights growing concerns over carrier security protocols.

Details of the SIM Swap Attack and Legal Outcome

A hacker targeted a T-Mobile customer in 2020. They used a SIM swap to hijack the phone number. This allowed access to the victim’s financial accounts.

Over $37 million in cryptocurrency was stolen. The law firm Greenberg Glusker represented the victim. They argued T-Mobile failed to implement basic security checks.

The arbitration panel awarded the victim $33 million. This decision was based on T-Mobile’s negligence. According to Reuters, the carrier discovered the swap within 16 minutes but could not prevent the theft.

T-Mobile’s Security Practices Under Scrutiny

Internal documents revealed ongoing security problems. T-Mobile allegedly had insufficient fraud prevention staff. About one hundred employees handled millions of accounts.

The company did not require strong identity verification. Employees often failed to ask for PINs or other details. This made SIM swaps relatively easy for attackers.

The firm also did not flag suspicious location changes. A number activated far from its home address raised no alarms. This lack of oversight contributed to the security breach.

The Associated Press has reported on similar issues across the telecom industry. T-Mobile’s case, however, involves one of the largest financial penalties to date. The company continues to face criticism over its data protection measures.

This landmark ruling underscores the critical need for robust consumer protections against SIM swap fraud. It signals a potential shift in holding telecom giants accountable for security failures.
