Security researchers have discovered new Bluetooth security flaws that allow hackers to impersonate devices and perform man-in-the-middle attacks.
The vulnerabilities impact all devices with Bluetooth 4.2 through Bluetooth 5.4, including laptops, PCs, smartphones, tablets, and others.
Users can do nothing at the moment to fix the vulnerabilities, and the solution requires device manufacturers to make changes to the security mechanisms used by the technology.

Companies like Apple make that difficult by making the widget only disable it for the day, and then the shit re-enables itself the next day.

That’s where most users will go to turn off their Bluetooth radio on an iPhone, but the true way to do this is in the Settings app, but you can’t blame users for not knowing that.

It's such an apple thing to do. "Alright, you want to turn off Bluetooth, okay. But we think it's better to have it on, and we know better, so, you know: Tomorrow's another day." At that point I don't own my device, I'm hostage negotiating with it.

Now that's just scummy. Yeah I can see how this can be a problem.

You can goto Settings and turn off Bluetooth completely. It's one of the first options in Settings.

I have a shortcut setup to turn it off and have the 3 tap on the back gesture to activate it. It’s always off unless I need it.

I did this too, but via Siri. Asking her to “disable WiFi” permanently turns it off because of the shortcut I created.
