Google to Fix Location Data Leak in Google Home, Chromecast
Krebs on Security
Google in the coming weeks is expected to fix a location privacy leak in two of its most popular consumer products. New research shows that Web sites can run a simple script in the background that collects precise location data on people who have a Google Home or Chromecast device installed anywhere on their local network.
Craig Young, a researcher with security firm Tripwire, said he discovered an authentication weakness that leaks incredibly accurate location information about users of both the smart speaker and home assistant Google Home, and Chromecast, a small electronic device that makes it simple to stream TV shows, movies and games to a digital television or monitor.
Young said the attack works by asking the Google device for a list of nearby wireless networks and then sending that list to Google’s geolocation lookup services.
