There’s some weirdness happening over at T-Mobile this morning. Multiple T-Mobile customers on X (formerly Twitter) and Reddit have reported that they’re able to see other users’ account data — including their current credit balance, purchase history, credit card information, and home address — when signing into their own T-Mobile accounts.

Some T-Mobile customers have mentioned seeing information from several other accounts, but the scale of the issue isn’t yet clear. It’s prevalent enough that the T-Mobile subreddit has asked its users to avoid posting any further information for “security reasons.”

T-Mobile later blamed the issue on a “technology update” glitch and said the problem had been fixed as of Wednesday afternoon. “There was no cyberattack or breach at T-Mobile. This was a temporary system glitch related to a planned overnight technology update involving limited account information for fewer than 100 customers, which was quickly resolved,” T-Mobile spokesperson Tara Darrow said in a statement emailed to The Verge.

The company has already had multiple security lapses this year, disclosing two separate cybersecurity attacks in January and May.

Misconfigured TeslaMate instances can leak tons of data on the internet, potentially exposing Tesla cars and their drivers to malicious attacks, IoT security intelligence firm Redinent reports.

A third-party data logging application, TeslaMate relies on the Tesla API to retrieve various types of information about Tesla cars, making it available to users on their computers.

While the application is a great tool for keeping track of car data, it also poses a significant risk if improperly configured, Redinent has discovered.
