The telecom giant said that the “bad actor” started stealing the data, which includes “name, billing address, email, phone number, date of birth, T-Mobile account number and information such as the number of lines on the account and plan features,” since November 25.

In the SEC filing, T-Mobile said it detected the breach more than a month later, on January 5, and that within a day it had fixed the problem that the hacker was exploiting.

The hackers, according to T-Mobile, didn’t breach any company system but rather abused an application programming interface, or API.

“Our investigation is still ongoing, but the malicious activity appears to be fully contained at this time, and there is currently no evidence that the bad actor was able to breach or compromise our systems or our network,” the company wrote.
