Security News > 2020 > March > Staffer emails compromised and customer details exposed in T-Mobile US's third security whoopsie in as many years

T-Mobile US was hacked by miscreants who may have stolen some customer information.

The hackers gained access to employee email accounts, which contained customer account information.

T-Mobile US was quick to reassure punters that financial information and Social Security numbers were not exposed.

Far be it from us to suggest that T-Mobile US is prone to springing the odd security leak or two, but back in 2018 the personal details of 2 million customers were spaffed, again with no financial data, and more than a million prepaid account holders had their privates ogled after the carrier was compromised again in 2019.

T-Mobile US reported strong customer growth last year, with more than 86 million by the end of Q4 2019 and revenues for the year at $34bn, although lurking in the small print where the company disclosed factors that might hit future results it does warn that "Inability to implement and maintain effective cyber security measures over critical business systems; breaches of our and/or our third-party vendors' networks, information technology and data security, resulting in unauthorized access to customer confidential information" might cause a wobble or two.
