Affected customers, which appears to not be many, have been sent letters informing them of the unauthorized activity that has taken place on their accounts. It was one of the biggest data breaches ever for a cell carrier, prompting the FCC to launch an investigation.Īs of now, T-Mobile has not publicly shared the news on their website. As mentioned, there was a massive data breach earlier this year in August that leaked data on nearly 50 million customers across both postpaid and prepaid accounts. T-Mobile doesn’t have the best track record when it comes to account security. Affected customers could have had both their private CPNI viewed as well as their SIM card swapped. The final category is simply both of the other two. The document says that customers affected by a SIM swap have now had that action reversed. This can, and often does, lead to the victim’s other online accounts being accessed via two-factor authentication codes sent to their phone number. This is where a malicious actor will change the physical SIM card associated with a phone number in order to obtain control of said number. The second category an affected customer might fall into is having their SIM swapped. That’s not great, but it’s much less of an impact than the breach back in August had, which leaked customer social security numbers. This information may include the billing account name, phone numbers, number of lines on the account, account numbers, and rate plan info. First, a customer may have only been affected by a leak of their CPNI. There is no further detail about what exactly happened, with the documents simply saying that some info was leaked.Īffected customers fall into one of three categories. It seems only a small subset of customers are affected. This time around, though, the damage appears to be much less severe. This comes just on the heels of a previous breach back in August. That activity was either the viewing of customer proprietary network information (CPNI), an active SIM swap by a malicious actor, or both. They state that there was “unauthorized activity” on some customer accounts. The news comes via internal documents shared with The T-Mo Report, embedded below. Here, only "customer proprietary network information" was leaked, meaning call logs, but no financial or social security information.T-Mobile just can’t catch a break lately when it comes to account security, as it seems there has been another small data breach this month. "Information accessed illegally may have included names and addresses, phone numbers, account numbers, rate plans and features, and billing information," T-Mobile said.įor some users "Social Security numbers, financial account information, and government identification numbers."Ī spokesperson for T-Mobile said the December 2020 breach affected 0.2 percent of all T-Mobile customers, roughly 200,000 people. The March attack happened through the company's email vendor and affected some customers and employees. Prior to this massive breach which affects nearly half of T-Mobile's over-100 million customers, the company reported being hacked twice in 2020, in March and then again in December.

They said the breach came to light when a hacker began claiming in online forums he had millions of T-Mobile customer records to sell. "We have no indication that the data contained in the stolen files included any customer financial information, credit card information, debit or other payment information," the statement said, though it continued, "Some of the data accessed did include customers' first and last names, date of birth, SSN, and driver's license/ID information for a subset of current and former postpay customers and prospective T-Mobile customers." Their preliminary analysis showed that almost 8 million current postpaid customers and 40 million records of former or prospective customers who had at one point applied for credit with the company were taken in what the company called a "highly sophisticated cyberattack." This most recent breach is by far the largest and has affected at least 47 million current and former T-Mobile customers, according to numbers released by the mobile giant. The latest in the series of hacks on the company's millions of customers' data comes on the heels of two attacks in 2020, one in 2019, and another in 2018. T-Mobile confirmed their latest data breach affecting millions of customers in a statement on Tuesday, totaling five breaches in the last four years.
