T-Mobile has denied suffering another data breach following Thursday night reports that a threat actor leaked a large database allegedly containing T-Mobile employees' data.
The mobile carrier told BleepingComputer that the leaked data is believed to belong to an authorized retailer, which was breached earlier this year.
"There has not been a T-Mobile data breach. The data being referred to online is believed to be related to an independently owned authorized retailer from their incident earlier this year. T-Mobile employee data was not exposed," T-Mobile told BleepingComputer.
This data breach is believed to be related to Amtel, LLC, an authorized T-Mobile retailer doing business as the Connectivity Source brand, who warned of a breach earlier this year.
In May 2023, Amtel warned that they suffered a data breach on April 19th that allowed the attackers to steal data for current or former employees of the company.
T-Mobile hacked to steal data of 37 million accounts in API data breach.
