Corona self-test falsified via Bluetooth

The researchers at F-Secure have succeeded in designing the result of a corona self-test as they wish.

With the help of the Android app for the corona self-test, the desired status can be changed relatively easily. There were also no difficulties in the subsequent review of the test certificate created in this way. Here, the service provider Azova was duped, who is responsible for checking travelers to the USA, among other things.
