T-Mobile USA has reported a data breach - its fourth in three years.

The wireless carrier disclosed the breach last week via its website, saying that it detected and shut down "Malicious, unauthorized access to some information" related to T-Mobile accounts.

The good news is that the data accessed did not include names on the account, physical or email addresses, financial data, credit-card information, Social Security numbers, tax ID, passwords or PINs, the wireless company said in the notice.

In 2019, about 1.26 million of T-Mobile's prepaid were affected by a breach that included names, billing addresses, phone numbers, account numbers and CPNI. The 2020 breach meanwhile impacted both employees and customers.

Cybercriminals accessed employee email accounts, some of which contained account information for T-Mobile customers, including names and addresses, phone numbers, account numbers and more.

It should be noted that T-Mobile and Sprint were also impacted by an incident in December 2019, where hundreds of thousands of mobile phone bills for AT&T, Verizon and T-Mobile subscribers were laid open to anyone with an internet connection, thanks to the oversight of a contractor working with Sprint.
