T-Mobile Cyberattack Reportedly exposed Customer Info and SIMs

T-Mobile has suffered another cyberattack after being rocked by a massive data breach in August.

This time around, attackers accessed “a small number of” customers’ accounts, according to documents posted by The T-Mo Report.

According to the report, customers either fell victim to a SIM swapping attack (which could allow someone to bypass SMS-powered two-factor authentication), had personal plan information exposed, or both. The document shows that the customer proprietary network information that was viewed could’ve included customers’ billing account name, phone and account number, and info about their plan, including how many lines were attached to their account.

This summer, the carrier confirmed that a data breach exposed almost 50 million customers’ data, with the attacker accessing social security numbers, names, and dates of birth. (A person who claimed to be the hacker went on to call the company’s security practices “awful.”) The information reportedly exposed in December’s breach is less sensitive (and the documents say the customers who had their SIMs swapped have regained access), and is likely not as large in scope. We weren’t able to find widespread reports from customers that said they’d received notification letters.

T-Mobile’s support account has seemingly confirmed that there was a breach, responding to people on Twitter to say that it’s taking “immediate action” to help individuals who were put at risk by the attack.

T-Mobile suffers a data breach, again

According to a new report, T-Mobile has undergone a small-scale data breach days before the year 2021 ends. The news comes a few months after the company suffered a large-scale data breach in August 2021. The new data breach affected a small number of users who were allegedly a target of a SIM swapping attack.

According to the report, many T-Mobile customers received the “unauthorized activity” notification from the mobile carrier. “That activity was either the viewing of customer proprietary network information (CPNI), an active SIM swap by a malicious actor, or both,” explains the report from The T-Mo Report. In simple terms, customers who were the victim of the breach were a target of a SIM swapping attack or had their personal information exposed, or both.

The markets are still looking for the Santa clause run. T-Mobile US Inc.’s merger with Sprint Corp. was supposed to create a supercharged wireless competitor pushing innovations, lowering prices, and staying true to its core principle — standing up for customers. Lately, it’s been falling down.

Jan. 6 rally organizers sue Verizon to stop the release of cell phone records. The House Jan. 6 committee had subpoenaed the records as part of its probe. T-Mobile has not responded yet.

Unfortunately, traditional cell phone companies are not doing much to protect customers. It is not all bad news, a cellular phone company named efani has stepped up and made it more difficult for hackers.

The holidays are here and hackers and scammers want your hard-earned money.

Your cellphone could provide a gateway for cybercriminals to access all your financial and social media accounts.

The fraud is known as a SIM Swap, SIM swapping, SIM hacking, or SIM jacking, Cybercriminals hijack your cellphone number and use it to gain access to your sensitive personal data and accounts.

Your bank account uses text-based two-factor authentication using your phone number after you enter a user name and password. The bank sends an access code to the cellphone number to complete the log-in process.

What if fraudsters are able to change the SIM card connected to your mobile number? A SIM Swap turns control of the number to a scammer who will receive the access code to your account.
