The Google Home Hub is deeply insecure

Security advocate Jerry Gamblin has posted a set of instructions – essentially basic lines of XML – that can easily pull important information off of the Google Home Hub and, in some cases, temporarily brick the device.
The Home Hub, which is essentially an Android tablet attached to a speaker, is designed to act as an in-room Google Assistant. This means it connects to Wi-Fi (and allows you to see open Wi-Fi access points near the device), receives video and photos from other devices (and broadcasts its pin), and accepts commands remotely (including a quick reboot via the command line).
