Chinese phone maker OnePlus is accused of leaving a debugging app on its phones capable of giving adversaries root access to the devices. The application in question is called EngineerMode and is made by Qualcomm.
An anonymous researcher who goes by the handle Elliot Alderson, a character in the TV drama Mr. Robot, discovered the tool that he said could act as a “backdoor” by adversaries to access data on devices.
In an interview with Threatpost, the researcher said he examined the latest firmware for the OnePlus 5 handset downloaded from the company’s website.
