  • 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.

Sure mate, do you ever take your car out of the garage or do you just leave it there in case it breaks down on the way to the shops?

I use Bluetooth devices with my phone all day every day. Car, headphones, watch, laptop, speakers. It's fine if you don't, but surely you can recognise that leaving bluetooth on for most people is about functionality rather than mere laziness.

That said, I'm not at all surprised that a vulnerability exists. Consumer tech just isn't built to be resilient in that way.
