Dolphin In The Lab
Hands-On Homelab Hacking and Pentesting with the Flipper Zero
This book is 100% completeLast updated on 2026-11-12
The Flipper Zero became famous by looking like a magic key. It isn't one — it's the best pocket-sized way to truly understand the radios, cards, and buses that run the physical world. Across fourteen hands-on chapters you'll build a safe homelab and work every interface the Flipper touches. Every offensive chapter ends with its defensive mirror: how to detect the attack, and how to shut it down. Everything is built for hardware you own, inside a lab you control — in scope, in-band, and within the law.

About the Book
The Flipper Zero became famous by looking like a magic key. It isn't one — it's the best pocket-sized way to truly understand the radios, cards, and buses that run the physical world. Dolphin in the Lab turns that curiosity into real, defensible skill.
Across fourteen hands-on chapters, you'll build a safe homelab and work every interface the Flipper touches — capturing and replaying Sub-GHz signals, cloning legacy access cards, reading hardware debug ports and dumping firmware, injecting keystrokes, standing up Wi-Fi recon, and writing your own Flipper testing apps in Python and C. Every offensive chapter ends with its defensive mirror: how to detect the attack, and how to shut it down. You'll finish by scoring findings with CVSS and chaining everything into a full capstone assessment with a professional report.
What you'll learn
- Capture, analyze, and replay Sub-GHz — and see why rolling codes defeat it
- Clone 125 kHz RFID, and understand why modern NFC won't clone
- Read UART, SPI, and I2C — and dump firmware off a flash chip
- Inject keystrokes with BadUSB, then catch it with Sysmon and Sigma
- Stand up Wi-Fi recon with the ESP32 dev board — legally
- Write your own Flipper test apps in Python, C, and Bash
- Score findings with CVSS and write reports that get fixes shipped
- Chain it all together in a full capstone assessment
Who it's for
Aspiring and early-career penetration testers, red and blue teamers, and serious hobbyists who are comfortable at a Linux command line. No prior RF or hardware experience required — the book builds that.
Lab-safe by design. Every technique is built for hardware you own, inside a lab you control — in scope, in-band, and within the law.
