T-Mobile confirmed latest data breach affecting millions of customers

US telecom giant T-Mobile has confirmed their latest data breach affecting nearly 8 million customers was accessed by a hacker, totaling five breaches in the last four years.

Their preliminary analysis showed that almost 8 million current postpaid customers and 40 million records of former or prospective customers, who had at one point applied for credit with the company, were taken in a 'highly sophisticated cyberattack.'

The latest in the series of hacks on the company's customers' data comes on the heels of two attacks in 2020, one in 2019, and another in 2018. This most recent breach is by far the largest.

News broke that a hacker was trying to sell T-Mobile customer data online, data they claimed to have gotten via compromised T-Mobile servers. They claimed the data contained names, addresses, social security numbers (SSN), driver license information, phone numbers and unique IMEI numbers.
