Proxmark3 is an open-source hardware tool for RFID research, analysis, security testing, protocol sniffing, tag cloning, and emulation. It operates across both low-frequency and high-frequency bands, providing a single platform for interacting with a wide range of contactless cards and tags including MIFARE, iCLASS, HID Prox, Hitag, Indala, and T55xx transponders. The tool is built around an FPGA that handles direct RF signal demodulation and modulation, enabling raw waveform capture and decoding. It includes a cryptographic attack framework capable of recovering secret keys through nested, h
FlipperAmiibo is a hardware NFC interface and emulator designed to read and write NFC data to mimic amiibo figures on compatible hardware devices. It functions as an NFC tag writer that transfers binary data to NFC chips to simulate official figure identities. The tool manages the deployment of NFC data files to a physical emulator, enabling the simulation of physical figure scans to interact with Nintendo console games. This process involves loading specific data files onto a compatible NFC device to unlock in-game content. The system covers hardware peripheral programming, binary file mapp
Xtreme-Firmware is a custom operating system for the Flipper Zero designed to expand hardware capabilities and remove software restrictions. 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
ESP32-DIV is a handheld wireless pentesting platform designed for analyzing and disrupting a wide range of wireless protocols. It functions as a multi-band radio analyzer, RFID and NFC tag manipulator, and GPS wardriving logger, providing a unified interface for security auditing and signal research. The project distinguishes itself through a modular radio abstraction that allows switching between Wi-Fi, BLE, Sub-GHz, RFID/NFC, and infrared hardware modules. It features a touch-driven TFT interface for navigating toolsets and managing signal profiles, as well as the ability to emulate Bluetoo
