Check Point researchers have warned of a security hole in microchips used in almost a billion Android devices that if exploited could give hackers complete access. The set of vulnerabilities, dubbed QuadRooter, were disclosed during a session at Def Con in Las Vegas.

Check Point has released a free scanner app to help Android users know if their personal devices are at risk.”]
