offensive-z-wave SKILL.md skillA
offensive-z-wave from miosa-osa/osa is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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@sha256:7dfe5ff2f4fa5b98The line at the top of this page pins the label git:20260913.e13b6b8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
