Breach exposed details of 2 million T-Mobile US customers

T-Mobile is notifying some customers about a recent security breach

T-Mobile experienced a data breach on August 20th

About 3 percent of T-Mobile's 77 million customers were affected, the company said in a statement to The Washington Post.

Hackers were able to gain access to customer information that included names, billing zip codes, email addresses, phone numbers and account data, the telecom company said on its website.

T-Mobile has announced that earlier this week it suffered a security breach that resulted in some personal information being obtained by malicious individuals.

A detailed article in Motherboard noted T-Mobile believes the hack was conducted by "an worldwide group" that accessed company servers through an API that "didn't contain any financial data or other very sensitive data".

A sign for a T-Mobile store is seen in Manhattan, New York, U.S., April 30, 2018. Once a hacker has your account number, phone number, and email address, it's easier for them to obtain your login information. The carrier is also sending out SMS messages to notify customers who might have been affected.

T-Mobile discovered and shut down a breach that the company says could have exposed some customers' personal information.

The breach was spotted on 20 August by the firm's cyber-security team, it said, and was plugged the same day.

T-Mobile and division Metro PCS encourages customers with question to reach out to a customer service agent by dialing 611 from their device. Credit card numbers, social security numbers and passwords weren't accessed, the company noted.
