Flipper Zero is a portable multi-tool for pentesters, security researchers, and hardware hackers. At first glance, it looks like a small toy with a digital pet dolphin on its screen, but inside it’s packed with powerful features for exploring and testing security systems.
Key Features of Flipper Zero:
1. RFID/NFC Reader & Emulator
Can read, store, and emulate different access cards.Useful for testing building access systems, hotel key cards, or metro cards.
2. Sub-GHz Transceiver
Allows you to capture and replay radio signals (like garage doors, IoT devices, car remotes).Perfect for researching vulnerabilities in wireless communication.
3. Infrared Remote Control
Can act as a universal remote for TVs, ACs, projectors, and any IR-based device.Useful in security testing of IR communication.
4. GPIO Pins for Hardware Hacking
Connect directly to hardware, IoT boards, and debug interfaces (UART, SPI, I2C).Helps in reverse engineering devices.
5. BadUSB Functionality
Works like a USB HID attack tool (similar to Rubber Ducky).Can automate keystroke injections or test endpoint security.
6. Dolphin Virtual Pet 
The dolphin grows and evolves based on your usage.Makes learning and experimenting fun and interactive.
Why It’s Popular?
Small and portable - fits in your pocket.Beginner-friendly but still powerful for advanced researchers.
Open-source firmware and active community support.
Great for IoT, RFID, and radio frequency pentesting.
Important: Flipper Zero is a research and educational tool. Using it against systems without permission is illegal. Always use it in authorized environments like labs, bug bounty testing, or with client consent.
This tool has become a must-have gadget for modern hackers and security researchers who want to explore the hidden side of digital systems.
