T-Mobile supplied FOX Business with the following statement.
"As soon as our teams identified the issue, we shut it down within 24 hours. Our systems and policies prevented the most sensitive types of customer information from being accessed, and as a result, customer accounts and finances should not be put at risk directly by this event. There is also no evidence that the bad actor breached or compromised T-Mobile’s network or systems."
T-Mobile said it has notified law enforcement and federal agencies.
The wireless carrier has had prior security breaches.
