It functions as a multi-protocol signal emulator for capturing and replaying RFID, NFC, Sub-GHz, and Infrared signals to test hardware security. The project features a specialized USB HID attack framework for sending keystroke payloads and spoofing device identifiers over USB and Bluetooth. It also includes a WiFi penetration testing suite for scanning, sniffing, and sending deauthentication frames using a wireless development board. Broad capabilities cover radio frequency analysis, infrared remote bruteforcing, and access control code fuzzing. The system provides tools for hardware interface customization, including visual asset pack management and a progressive content unlocking system based on numerical levels. Additional utility is provided through a USB to UART bridging system and a built-in command line interface. ## Tags ### Mobile Development - [Custom Hardware Firmware](https://awesome-repositories.com/f/mobile-development/mobile-operating-systems/firmware-customization-tools/custom-firmware-integration-systems/custom-hardware-firmware.md) — Provides a modified operating system for Flipper Zero that removes software restrictions and expands hardware capabilities. ### Part of an Awesome List - [RFID and NFC Security](https://awesome-repositories.com/f/awesome-lists/security/rfid-and-nfc-security.md) — Reads and mimics contactless tags and physical keys to test access control systems and identify hardware identifiers. - [Sniffing and Spoofing](https://awesome-repositories.com/f/awesome-lists/security/sniffing-and-spoofing.md) — Harvests beacons, deauthentication frames, and authentication data from wireless clients.
