Comment Is long-range Bluetooth a feature, or a bug? (Score 1) 82
Never a fan of Bluetooth, I use it for a few things that refuse to use other connections. I thought that the limited range was a good thing, both for security and to prevent confusing cross-talk. 600 km Bluetooth reception (according to the article referenced here) doesn't immediately strike me as a good thing.
A tech adjusting my BIotronik pacemaker from across the room told me he was connecting with Bluetooth. There are definitely at least two wireless communications enabled, at least one of them allows changes to the settings. The medical techs working on my pacemaker mostly have no technical knowledge of it, so he may have just referred to all wireless as "Bluetooth." It's ridiculously hard to find reliable and understandable technical information for my own use. I observed that my first implant was adjusted wirelessly at very short range through an antenna placed on my chest. The new one (battery depleted after 10 years) was adjusted from across the room. So Bluetooth is possible, and disturbing.
I'm pretty sure that the worst a hacker could do to me is turn pacing off, so I became very faint, or running it ridiculously high, which I would survive. If I had the defibrillation feature, it would be a lot worse. The really scary possibility is that insulin pumps could be vulnerable, and it would be easy to kill someone through control of the insulin pump.
