A team of cybersecurity researchers has discovered a clever technique 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. 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. "By modulating an electrical signal in the intensity of a light beam, attackers can trick microphones into producing electrical signals as if they are receiving genuine audio," the researchers said in their paper [ PDF ]. Doesn't this so

If your Google Home, Home Mini and/or Google Chromecast streaming stick were not working properly, you are not alone. Google Home, Home Mini, and Chromecast were down globally for many users for several hours, leaving a lot of people with trouble watching TV, controlling smart home gadgets, and listening to music. Yesterday, hundreds of Chromecasts and Home users began complaining about their devices not working properly on both the official "Made by Google" Twitter account and Down Detector. Later, Google confirmed that its Home and Chromecast across the world went down due to an unspecified "issue," and that the company was investigating the issue and working on a solution, but did not provide any kind of explanation about the glitch. The issue appears to be affecting devices that work using Google's Home technology, which is a smart ecosystem that allows users to stream content to devices. "Bug confirmed... We use Chromecast in all our conf

Remember BlueBorne? A series of recently disclosed critical Bluetooth flaws that affect billions of Android, iOS, Windows and Linux devices have now been discovered in millions of AI-based voice-activated personal assistants, including Google Home and Amazon Echo . As estimated during the discovery of this devastating threat, several IoT and smart devices whose operating systems are often updated less frequently than smartphones and desktops are also vulnerable to BlueBorne. BlueBorne is the name given to the sophisticated attack exploiting a total of eight Bluetooth implementation vulnerabilities that allow attackers within the range of the targeted devices to run malicious code, steal sensitive information, take complete control, and launch man-in-the-middle attacks. What's worse? Triggering the BlueBorne exploit doesn't require victims to click any link or open any file—all without requiring user interaction. Also, most security products would likely not be abl
