T-Mobile hack may have affected around a million customers

T-Mobile customers have been caught up in a recent hack, the company said on Friday.

T-Mobile told TechCrunch that “less than 1.5%” of its customers had been affected, meaning around a million people may have had their data compromised in the incident.

The intrusion, which has alarming echoes of another T-Mobile hack in 2018, was discovered earlier this month and shut down immediately, the company said. We’ve reached out to T-Mobile for more information about the precise nature of the breach and will update this piece if we hear back.

In a message to affected customers, America’s third most popular carrier said that its cybersecurity team had recently discovered “malicious, unauthorized access to some information” related to T-Mobile accounts.

It said the stolen data is likely to have included information associated with a customer’s prepaid service account, including name, billing address (if one was provided when the account was set up), phone number, account number, rate plan, and details of any added features, such as international calling.

T-Mobile was keen to reassure customers that no financial data, such as payment card numbers, was taken in the breach, nor were any social security numbers involved. Account passwords are also safe, it said.

2018 breach

This month’s hack follows a similar one that affected around 2 million T-Mobile customers in August 2018, which the company blamed on an unidentified group of international hackers.

While any security breach has to be taken seriously, the nature of the stolen data in this latest incident could have been a lot worse. But affected customers will likely still be upset that hackers were able to breach the company’s cyber defenses for the second time in just over a year, with the stolen data potentially proving useful to criminals intent on misdeeds such as identity theft or account hijacking.

News of the hack comes just days after John Legere, T-Mobile’s charismatic CEO, announced he will step down in April 2020 after seven years in the hot seat. Mike Sievert, T-Mobile’s current president and chief operating officer, is expected to replace Legere as the company continues to prep its expected merger with Sprint.

T-Mobile just set another 5G speed record

T-Mobile’s rivals may be nipping at its heels in the 5G race, but the Uncarrier is determined to stay ahead of the game. It not only boasts the fastest and most expansive 5G network in the U.S., but it’s actively working on technologies that will help it reach even greater peak speeds.

Two years ago, T-Mobile used a relatively new technique known as 5G Carrier Aggregation (5G CA) to achieve the kind of 3Gbps download speeds on midband frequencies that had previously been the exclusive domain of extremely high (and extremely short-range) mmWave technologies. Now, it’s chalked up another 5G first by taking advantage of the latest developments to shatter the traditional cap on upload speeds over sub-6GHz frequencies.

T-Mobile is a consistent leader in the ongoing 5G race, and to kick off 2024 on an interesting note, the carrier has announced that a big change is coming to its T-Mobile Tuesdays app. In short, the app is going away — and in its place, a new one is launching soon.

If you open the T-Mobile Tuesdays app today, January 2, you'll see a card that says "Introducing T Life." Below that is additional text that describes T Life as "a new app for T-Mobile Tuesdays."

Use Comcast for internet? Your personal data may have been hacked

Comcast, alongside several other big corporations, has recently suffered a devastating data breach. According to reports, it's possible that hackers got their hands on the data of up to 36 million Comcast Xfinity customers, meaning the company's cable television and internet department. Although the company is pretty tight-lipped about it, the data breach occurred over two months ago. Here's what we know and what you should do to protect yourself.

The hackers were able to access those masses of customer information through a vulnerability known as "CitrixBleed." It's found in Citrix networking devices that Comcast and other huge corporations use. The exploit was initially discovered in August and appears to have been used in cyberattacks on not just Comcast but also many other companies, including Boeing.
