This repository contains a proof-of-concept (POC) exploit for a vulnerability in Apple's iOS bluetoothd service, targeting iOS versions 11.3.1 to 11.4 (tested on iPhone 6S). The exploit is implemented in Objective-C across two files: 'toothfairy.h' (header) and 'toothfairy.m' (main exploit logic). The exploit crafts and sends Mach messages to the 'com.apple.server.bluetooth' Mach service, manipulating message fields to set the program counter (PC) of the bluetoothd process to an attacker-controlled value (0xdeadbeef). This can potentially allow code execution or sandbox escape. The exploit leverages knowledge of Mach message structure and specific message IDs and offsets within the bluetoothd service. The repository includes a README with background, references, and credits, but the core exploit logic is in 'toothfairy.m'. No network endpoints are used; the attack vector is local, requiring the ability to send Mach messages to system services. The exploit is a POC and does not include a weaponized or easily customizable payload.
