About Hacker Playground
We publish hands-on guides for wireless and hardware security research with a focus on lab-safe troubleshooting, clear explanations, and a permission-first ethic.
What we cover
- Wireless fundamentals: Wi‑Fi, BLE, RFID/NFC, Sub‑GHz, IR, SDR basics and terminology.
- Practical workflows: How to set up tools, capture data in a lab, and interpret results.
- Troubleshooting: Step-by-step checklists for the common “why doesn’t this work?” problems.
- Defense mindset: Understanding what modern security controls prevent (and why).
Our baseline rules
- Authorization required: Only test systems you own or have explicit written permission to assess.
- Containment: Keep experiments controlled and avoid impacting others (power, range, timing).
- Minimize data: Prefer synthetic/lab data and redact anything sensitive.
