Amid rising cases of cybercrime across the globe, telecommunication giant T-Mobile said on Sunday that the company is investigating a claim made in an online forum that the personal data of over 100 million users has been breached.
Although the post on the said forum doesn't mention T-Mobile, the seller told The Vice news website that they obtained data related to over 100 million people and that the data came from the Germany-based company's servers.
"The Data includes social security numbers, phone numbers, names, physical addresses, unique IMEI numbers, and driver licenses information, the seller said," according to The Vice reports. The news platform has seen samples of the data, and confirmed they contained accurate information on T-Mobile customers
Meanwhile, on being asked by Reuters about the alleged breach, a T-Mobile spokesperson said in a statement, "We are aware of claims made in an underground forum and have been actively investigating their validity. We do not have any additional information to share at this time."
However, the seller has been asking for 6 bitcoin (approximately $270,000) on the forum for a subset of the data containing 30 million social security numbers and driver licenses. The individual also informed that he was privately selling the rest of the data at the moment.
"I think they already found out because we lost access to the backdoored servers," the seller said, referring to T-Mobile's potential response to the breach, according to The Vice reports.
Apparently, T-Mobile has kicked the hackers out of their servers after the initial attack, but the seller said he had already downloaded the data locally.
"It's backed up in multiple places," they said.
The name of the forum where the claim was posted has not yet been disclosed.
