Armed with key tidbits of information like account numbers, those scammers will sound much more convincing, he said. Meanwhile, Fier, who spent more than a decade working in counterterrorism before joining Darktrace, said nation-state hackers could also use the data to connect the dots between people for intelligence purposes.įor the more average person, there's a bigger possibility they'll be targeted by scammers, possibly impersonating T-Mobile, either by phone or email. Put your carrier's number in your phone as a contact: AT&T: 1-80. In addition, all wireless customers should make sure that their accounts are secured with a PIN or passcode, which also can help stop SIM swaps, he said. Here are the customer service numbers for each major carrier. That's why, Wisniewski said, it's important that consumers, especially those compromised in the T-Mobile breach, not use SMS as a two-factor authentication method for bank, retirement, cryptocurrency and other critical online accounts. Doing that could give them access to not only the wireless number and account, but also any two-factor authentication codes that might come to the phone via SMS.

ABC News wrote that T-Mobile was breached by hackers, while Red Ventures website CNET which has faced some scrutiny for using robots to write stories claimed T-Mobile got hacked again. How do they know those numbers? They tricked the account holder into calling. T-Mobile on Monday said it experienced a hack that exposed account PINs and other customer data in the company's second network intrusion this year and the ninth since 2018. The hackers claim they actually stole data on 100 million people. Researchers were able to pose as account holders who had forgotten their PIN or passcodes, oftentimes providing recent outgoing calls from the target phone number, called by the actual account holder. Having had the personal data of 30 million customers hacked last year, T-Mobile used a third party to contact and pay the hackers a 200,000 to stop it leaking however they just sold it anyway, according to Vice’s tech arm Motherboard.
