The KNOB Attack: Does this exploit from 2018 still work?

This entry is part 29 of 32 in the series [ Hacker Night School ]

Here’s an awesome Bluetooth exploit from 2018 that EVERY device was vulnerable to, called the KNOB attack. “We found and exploited a severe vulnerability in the Bluetooth specification that allows an attacker to break the security mechanisms of Bluetooth for any standard-compliant device. As a result, an attacker is able to the listen, or change the content of, nearby Bluetooth communication, even between devices that have previously been successfully paired … All devices that we tested were vulnerable to the KNOB attack.” Hmm, I wonder if they’ve fixed this? Sounds like some security testing is in order here.
