Bluetooth-Controlled Door Lock
That’s pretty cool, and I can imagine all sorts of reasons to get one of those. But I’m sure there are all sorts of unforeseen security vulnerabilities in this system. And even worse, a single vulnerability can affect all the locks. Remember that vulnerability found last year in hotel electronic locks?
Anyone care to guess how long before some researcher finds a way to hack this one? And how well the maker anticipated the need to update the firmware to fix the vulnerability once someone finds it?
I’m not saying that you shouldn’t use this lock, only that you understand that new technology brings new security risks, and electronic technology brings new kinds of security risks. Security is a trade-off, and the trade-off is particularly stark in this case.
