The Flipper Zero landed in the mainstream as “that hacker toy,” but underneath the dolphin is a genuinely capable multi-tool: sub-GHz radio, RFID/NFC, infrared, iButton, GPIO, and a scriptable BadUSB stack. Cosette Mazet and I walked through what each subsystem actually does, where the practical security implications are, and how the device fits into real assessment work rather than TikTok theatrics.
The centerpiece was live: capturing and defeating the rolling-code scheme of a twenty-year-old garage door opener on stage, and using that walk-through to explain why rolling codes exist, how early implementations aged badly, and what modern receivers do differently.
Key takeaways
- What the Flipper Zero can and cannot do out of the box, separating capability from hype
- How rolling-code (hopping-code) garage systems work, and the weaknesses of early-2000s implementations
- Responsible-use framing: testing hardware you own, and what this class of tool means for defenders
