A from the Veritasium YouTube channel shows how a niche loophole could allow someone to steal $10,000 from a locked iPhone—though you probably don’t need to worry.

Apple ships new security updates for the iPhone all the time, and .

But a new video from Veritasium shows how a very specific vulnerability has been around since 2021, and remains unaddressed to this day.

Professors Ioana Boureanu and Tom Chothia discovered that a locked iPhone can be tricked into making an NFC payment. All it takes is a few unique hacks.

The method involves tricking an iPhone into thinking that a payment terminal is actually a mass transit terminal that’s using Apple’s ‘Express Transit’ feature. The video explains how the method then overcomes a couple other Apple safeguards so as to extract $10,000 from the iPhone.

You can below for more details:

The vulnerability only works when a Visa card is set up as iPhone’s ’Express Transit’ option in Settings. It doesn’t apply to Mastercard or other vendors.

Apple told Veritasium that the issue stems from a concern on Visa’s end.

Visa, meanwhile, said that its cardholders are protected by a zero liability promise that would cover any potential loss if the vulnerability was successfully exploited. However, it called the vulnerability “very unlikely” in real-world settings, despite it being possible within a highly controlled setup.
