⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.

Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

1. Ask the user to state the exact target URL, IP, account, or resource.
2. Ask the user to confirm written authorization and the permitted scope.
3. Show the exact command(s) and explain their expected effect.
4. Wait for explicit confirmation in the current conversation.

Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

RF / SDR Security Research

When to Use

• Lab study of wireless protocols with your own devices.
• Feasibility checks for replay attacks in RF-isolated environments.

适用场景

• 无线遥控/传感器等非 Wi-Fi RF（授权）
• ADS-B/遥控等协议研究（合法接收）
• 与 wifi-wireless 分工：本 skill 偏 SDR 通用 RF；Wi-Fi 攻防走 R29

工作流

□ 法规与许可确认
□ 只收：识别中心频率与调制
□ GNU Radio / URH 分析
□ 重放仅屏蔽室且书面允许
□ 结论侧重：是否可未授权控制 / 加固建议

工具链

工具	用途
RTL-SDR / HackRF（合规）	收发硬件
URH / GNU Radio	分析
Inspectrum	信号

路由上下文

上游: MASTER R38
MUST NOT: 干扰公共通信、未授权发射

任务完成自检

• 是否默认只收并记录法规边界？
• Checklist？

Limitations

• Transmitting on licensed frequencies is illegal without permits; shield and stay low-power.
• Protocol analysis quality depends on SDR bandwidth and sampling.
