Earlier last week, a researcher/programmer/ethical hacker Matt Kunze released a blog post detailing a severe vulnerability of Google smart home speakers that could give hackers remote control over the devices. In his blog post, Matt details how the vulnerability was discovered and then explains in frightening detail exactly how this backdoor could be used to access a wide range of commands and actions using the affected Google speaker.
The potential for attack stemmed from a vulnerability that could allow someone to add themselves to the Google Home App. From there, a hacker could control devices connected to the account. Once connected, an attacker could utilize voice commands to activate the microphone on a given device. You can imagine how much chaos could ensue from that point. The device could potentially be used to do anything that the Google speaker was capable of as it relates to any other connected devices in the home.
