Mobile telecommunications company T-Mobile announced the start of a probe into claims of clients’ data leaks.
The investigation started after an online forum post claimed to be selling the customers’ data stolen from T-Mobile’s servers. The data in question includes names, addresses, and Social Security numbers for more than 100 million people.
Initial reports confirmed the authenticity of the claim.
A T-Mobile spokesperson said: “We are aware of claims made in an underground forum and have been actively investigating their validity.”
In his post, the seller was asking for $270,000 in cryptocurrency, i.e. 6 bitcoins, to sell the data of 30 million customers.
This is not the first time T-Mobile has been a target of data breaches:
Hackers access the personal information of 2 million T-Mobile customers. The data accessed includes names, account numbers, and addresses.
Pre-paid customers were affected by a similar breach that accessed the same type of data.
A breach exposed customer’s Social Security numbers and financial information.
The most recent known breach has exposed call-related information and customers’ phone number while failing to acquire more sensitive information.
