Analyze RF protocols for security vulnerabilities

This skill studies non-Wi-Fi RF protocols and devices - remote controls, sensors, ADS-B - defaulting to receive-only work: confirming regulatory scope, identifying center frequency and modulation, and analyzing captures. It complements the wifi-wireless skill, which is scoped specifically to Wi-Fi, while this one covers general RF/SDR research.

Use it for lab study of wireless protocols with your own devices, or for feasibility checks on replay attacks strictly within RF-isolated environments. It is authorized-use-only: before any command that probes, transmits toward, or otherwise actively engages a target, the skill requires the user to state the exact target and confirm written authorization and scope, and to see the exact commands before they run. It must never be used to interfere with public communications or transmit without authorization, and any replay is performed only in a shielded room under written permission - never against a live, unauthorized target.

Input is an RF signal captured with SDR hardware within legal and licensed bounds. Output is the identified center frequency and modulation, a protocol-level analysis of the capture, and a conclusion focused specifically on whether unauthorized control of the device would be feasible, plus hardening recommendations.

RTL-SDR or HackRF, used compliantly, provide the receive (and, where authorized, transmit) hardware; GNU Radio or URH perform the protocol analysis; Inspectrum handles signal visualization.

Security researchers doing authorized RF/SDR assessments of non-Wi-Fi wireless devices and protocols, working under explicit written permission and lab-grade RF isolation for anything beyond passive reception.
