What happened

Google confirmed that a certified Android TV device maker slipped a hidden backdoor for malware onto its devices. According to the company, the flaw affects millions of Android TV and Google TV boxes.

What Google did

Google said it has shut down the backdoor. The company also announced security improvements for the ecosystem as a whole following the incident.

Why it matters

Android TV and Google TV boxes are devices users rarely touch directly and that update in the background. A manufacturer-level backdoor shows that certification does not necessarily cover every part of a device's software. Google's planned steps aim to prevent similar flaws on comparable devices.
