★ · LEGAL & RESPONSIBLE USE

Read this before you transmit.

★ The one rule

POSEIDON can receive and (when explicitly armed) transmit on regulated radio bands and can simulate networks. Use it only on devices and networks you own or have written authorization to test. Unauthorized use is a crime in most jurisdictions — and not the point of this project.

Your responsibilities

Authorization. Get explicit, written permission before testing any system, device, vehicle, or network you don't own. "I was just curious" is not a defense.
Radio regulations. Transmitting on sub-GHz / ISM / 2.4 GHz / 5 GHz / LoRa bands is regulated. You are responsible for complying with your local regime — e.g. FCC (US), Ofcom (UK), ETSI/CE (EU), or your national equivalent — including band, power, and duty-cycle limits. Some operations require a licence. Jamming and deauthentication against networks you don't control are illegal in most places.
Safety-critical systems. Never target systems where interference could endanger people or property — vehicles in motion, medical, industrial, aviation, emergency.
Data you capture. Handshakes, hashes, and Fast-Pair probes can contain other people's credentials and personal data. Handle, store, and dispose of captures lawfully; don't retain or share data you're not authorized to hold.

Built-in safety posture

POSEIDON ships safety-by-design: transmit-capable actions are gated behind a deliberate arm step, defaults are conservative, and identifying defaults are suppressed. Do not remove or weaken these gates. They exist to prevent accidental or unattended transmission — they protect you as much as anyone nearby.

Responsible disclosure

Tools like the WhisperPair probe (CVE-2025-36911) are built on top of published research and are intended as demonstration and self-check tools. If you discover a vulnerability using POSEIDON, follow coordinated disclosure: report it to the vendor and give them time to fix it before going public. Credit the researchers whose work you build on — see the Credits page.
