Security Analysis of Zigbee Networks with Zigator and GNU Radio
summary
Zigator uses GNU Radio with gr-ieee802-15-4 and gr-foo to capture IQ traces, parse and decrypt Zigbee with Python libs, and drive novel selective jamming and spoofed MAC acknowledgements implemented by modifying an 802.15.4 USB adapter firmware. Experiments run on 10 commercial devices produce a public dataset of over 500,000 packets collected across 34 hours and demonstrate a pan‑ID conflict attack that can disconnect devices; vendors issue firmware and spec mitigations after responsible disclosure.
