Yesterday we heard about an accidental backdoor on some OnePlus smartphones. The backdoor was an app called Engineer Mode that was used for diagnostics on OnePlus devices. The company has now released a statement.
The company will be removing the Engineer Mode app for their OnePlus handsets in a future OTA update, this includes the OnePlus 3, the 3T and the 5. You can see a statement frome them below.
Yesterday, we received a lot of questions regarding an apk found in several devices, including our own, named EngineerMode, and we would like to explain what it is. EngineerMode is a diagnostic tool mainly used for factory production line functionality testing and after sales support.
We’ve seen several statements by community developers that are worried because this apk grants root privileges. While, it can enable adb root which provides privileges for adb commands, it will not let 3rd-party apps access full root privileges. Additionally, adb root is only accessible if USB debugging, which is off by default, is turned on, and any sort of root access would still require physical access to your device.
You can find out more details about the OTA update that is coming to the handsets over at the company’s website at the link below.
