Jailbreaking The Apple HomePod: Fun With Checkm8 And Smart Speakers
summary
Achieves BootROM code execution on HomePod via the checkm8 exploit, remaps a bootrom page into SRAM to disable signature checks and uses a tethered-boot tool (rainsn0w) to load a patched iBoot and custom ramdisk, installs SSH and a writable bootstrap, and injects tweaks by patching posix_spawn and using DYLD_INSERT_LIBRARIES. Built a 3D printable USB adapter (and small PCB) to access the hidden connector. Demos include SpotifyD streaming from Android, Siri hooked to ChatGPT, mic audio exfiltration, works on tvOS 17, and jailbreak is fast (~5 minutes) with no persistent on-disk traces.
