T-Mobile has provided FOX Business with the following statement.

“Once our teams identified the issue, we closed it within 24 hours. Our systems and policies prevented access to the most sensitive types of customer information, and as a result, customer accounts and finances should not be directly compromised by this event. There is also no evidence that the attacker has breached or compromised T-Mobile’s network or systems.”

T-Mobile said it has notified law enforcement and federal agencies.

The wireless provider has had previous security breaches.
