OnePlus Phones Come Preinstalled With a Factory App That Can Root Devices (bleepingcomputer.com)
Catalin Cimpanu, writing for BleepingComputer: Some OnePlus devices, if not all, come preinstalled with an application named EngineerMode that can be used to root the device and may be converted into a fully-fledged backdoor by clever attackers. The app was discovered by a mobile security researcher who goes online by the pseudonym of Elliot Alderson -- the name of the main character in the Mr. Robot TV series. Speaking to Bleeping Computer, the researcher said he started investigating OnePlus devices after a story he saw online last month detailing a hidden stream of telemetry data sent by OnePlus devices to the company's servers.
No longer you have to tinker around and find an app you can install to root your device, now you can root it out of the box, delete the app to root it and you have a rooted device.
And even one where OnePlus cannot complain about you voiding your warranty by rooting it. Because who said you did it and not some malicious actor, using what they themselves handed to him?
