    A team of cybersecurity researchers has discovered a clever technique which  relies on a vulnerability in MEMS microphones embedded in voice-controllable systems to remotely inject inaudible and invisible commands into voice-controlled devices — all just by shining a laser at the targeted device instead of using spoken words. Learn more about this hack and how to protect yourself against it in real-life in a great The Hacker News article:

    Dubbed 'Light Commands,' the hack relies on a vulnerability in MEMS microphones embedded in widely-used popular voice-controllable systems that unintentionally respond to light as if it were sound.

    According to experiments done by a team of researchers from Japanese and Michigan Universities, a remote attacker standing at a distance of several meters away from a device can covertly trigger the attack by simply modulating the amplitude of laser light to produce an acoustic pressure wave.
