64,000,000 T-Mobile Records Containing Highly Sensitive Customer Data Allegedly Leaked Online As Mobile Giant Refutes Attackers’ Claims

Hackers say they just posted a massive new trove of T-Mobile customer data online – but the details of the data dump are in question.

Cyber thieves uploaded the data to a popular dark web forum, according to Cybernews.

The outlet’s researchers say a sample of the data appears to contain some emails linked to prior T-Mobile breaches, along with “some new data points not seen in previous T-Mobile attacks.”

But the mobile giant says the malicious actors are flat-out lying.

“Any reports of a T-Mobile data breach are inaccurate. We have reviewed the sample data provided and can confirm the data does not relate to T-Mobile or our customers.”

Researchers say the data contains full names, dates of birth, tax IDs, addresses, phone numbers, email addresses, device IDs, cookie IDs and IP addresses.

“If this data is legitimate, exposing 64M lines of highly sensitive information poses a serious threat of identity theft/fraud, surveillance, and further, better-targeted attacks on customers.”

The alleged data dump comes as 76 million T-Mobile customers begin to receive their share of a $350 million payout following a 2021 data breach and class action settlement.
