One More Thing to Worry About

Do you use a voice assistant to control any of your household devices? A recent hijack demonstration has shown that it's possible to take over an assistant using ultrasound signals - i.e. something that you and I cannot hear. The neatly-named DolphinAttack was not easy to achieve but never-the-less achieved it was. Furthermore, it's something that it should be relatively easy to guard against. However, it just shows that we need to be thinking widely about cyber-security at all times.
