False alarm triggering via replayed sensor frames
Published Jan 12, 2026 · Updated Jan 12, 2026
RF capture-replay in D3D Wi-Fi Home Security System ZX-G12 2.1.1 allows physically proximate attackers to trigger false alarm events. The alarm hub accepts static 433 MHz frames that match a paired sensor ID without authenticating the sender or checking freshness, nonces, counters, or sequence values. RF reception range and one captured legitimate sensor transmission are required; replay can spoof trigger or reset events without Wi-Fi access or physical access to the hub.
