● I remember using a symbian utility in school run time over a decade ago called ‘super Bluetooth hack’ that require user to accept DUN (Dial-Up Networking) request to device.
Once the user accept pairing request or the DUN request directly. The attacker then can initiate a call to a number remotely within the Bluetooth range. The same MMI code was used by me in one instance to forward all calls to my no.
In another instance; Bluetooth has FTP protocol within that lets the end user access memory of the other device that enables a copy of media files.
