offensive-z-wave skillA
offensive-z-wave is agent-read markdown (skill) from miosa-osa/osa: 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..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# 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 --- ## Hardware | Adapter | Use | |---|---| | Z-Force (legacy, hard to find) | Original research tool | | EZ-Wave (custom HackRF firmware) | Modern, full transceiver | | Aeotec Z-Stick | Commercial controller, useful as legitimate node | | HackRF + open Z-Wave firmware | Multi-band SDR approach | | RTL-SDR + ZniffMobile (passive only) | Cheap sniffer | ## Sniffing ```bash # EZ-Wave (HackRF firmware-based) git clone https://github.com/cureHsu/EZ-Wave ezwave-sniff -f 908.4MHz -o capture.pcap # Wireshark with the Z-Wave dissector parses captured frames wireshark capture.pcap ``` …

How to install
mdr add miosa-osa/osa/offensive-z-wave@git:20260913.e13b6b8mdr add miosa-osa/osa/offensive-z-wave@sha256:7dfe5ff2f4fa5b98Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
