Harden key management and commissioning for Zigbee, Thread, and Matter mesh networks against key capture, replay, rogue joining, and commissioner or Trust Center impersonation, including network-key capture under the default ZigBeeAlliance09 link key, insecure rejoins, touchlink abuse, and Matter setup passcode guessing (MITRE ATT&CK T1040, T1557, T1110; ICS T0887, T0860, T0830). Signals come from hub and border-router telemetry: Zigbee2MQTT, Home Assistant ZHA, deCONZ, OpenThread Border Router otbr-agent and ot-ctl, and Matter controller logs. Gives detectable join and key-management signals, a hypothesis-driven hunt, and a hardening plan mapped to ISO 27001 and NIST CSF. Use when hardening a Zigbee, Thread, or Matter deployment, hunting rogue joins or touchlink abuse, triaging unexpected device_joined or permit_join events, reviewing install-code versus global-link-key provisioning, or watching for new Matter fabrics.
