T-Mobile hacked in massive Chinese breach of telecom networks, WSJ reports

Hackers linked to a Chinese intelligence agency were able to breach T-Mobile as part of a monthslong campaign to spy on the cellphone communications of high-value intelligence targets, the Journal added, without saying when the attack took place. "T-Mobile is closely monitoring this industry-wide attack, and at this time, T-Mobile systems and data have not been impacted in any significant way, and we have no evidence of impacts to customer information," a company spokesperson told WSJ. It was unclear what information, if any, was taken about T-Mobile customers' calls and communications records, according to the report.
