Dev uses agents to reverse-engineer Sonos firmware, achieves root on all his devices
doodlestein · x · 2026-11-04
Developer doodlestein is closing in on "FrankenSonos": rooting all his Sonos devices to replace firmware and finally fix them. Screenshots show agent-driven reverse-engineering results — Unicorn PPC32 emulation proving attacker-controlled code execution in the root daemon, with a full exploitation chain (pre-traffic fills the session arena, URL bytes become the vtable pointer) and on-device confirmation of a 14.6s crash with 0.2s watchdog recovery. He notes the big breakthroughs came from prodding the agents to do specific things; the uncensored models couldn't figure it out on their own.
