I know tech reporting has gone downhill, but I was really surprised by how badly this minor issue was overhyped.. articles with titles like "Hidden Backdoor Discovery Could Expose 1 Billion Bluetooth Devices To Hackers" coming out even yesterday. It's a stretch to even call this a back door.
The headlines I saw were irresponsible journalism, plain and simple. There ought to be some significant repercussions or at least apologies and lessons learned posts for those publications and/or authors for crying wolf.
I cant say exactly which ones, but the main problem to me is the "second hand news".
probably most news outlets didn't made any research, they just rewrote what the previous outlet published.
as in, "we don't know either, but those guys do!"
so they probably went confident that they weren't wrong with the argument that someone else did the research for them.
i wouldn't dare call them journalists, and it is rather unlikely all of them independently reached the same conclusion that this is a "massive vulnerability".
That means you could attach wires to any device and simply overwrite the firmware on them, replacing it with your own. If that's not a severe security vulnerability, I don't know!
