Unleashed Firmware is a custom firmware modification for portable multi-tool devices designed to expand the capabilities of radio frequency, infrared, and contactless authentication hardware. It functions as a comprehensive platform for wireless security auditing, signal analysis, and hardware interaction, enabling users to capture, decode, and emulate signals across various communication protocols. The firmware distinguishes itself through a modular plugin architecture that allows for the dynamic addition of signal analysis and attack capabilities without requiring a full system recompile. I

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
