Z-Wave attack methodology — sniffing with Z-Force / EZ-Wave / RTL-SDR + ZniffMobile, S0 (legacy) network-key derivation flaw and key reuse, S2 (modern) ECDH commissioning analysis, replay/injection on unauthenticated nodes, default-key brute-force on test deployments, and home-automation hub pivots. Use when targeting Z-Wave smart home devices (door locks, sensors, garage controllers) — common in mid-2010s smart home deployments still in production.

# Z-Wave Attacks
Z-Wave runs in the 800/900 MHz ISM band (US: 908 MHz, EU: 868 MHz). Older networks used the S0 security scheme with a fixed-derivation network key — long-known to be flawed. S2 (mandatory for Z-Wave Plus v2 since 2017) uses ECDH commissioning and is significantly stronger.
## Quick Workflow
1. Identify region (US 908 MHz / EU 868 MHz) — adapter frequency must match
2. Sniff inclusion (commissioning) traffic — that's where keys are exchanged
3. Determine S0 vs S2 from frame format
4. For S0: derive/replay; for S2: analyze ECDH and look for implementation flaws
