HF_COLIN — VIGIKPWN MIFARE Classic Ultra-Fast Sniff/Sim/Clone

Author: Colin Brigato Frequency: HF (13.56 MHz) Hardware: RDV4 (requires flash memory)

What

A specialized MIFARE Classic attack mode designed for French VIGIK access control systems. It performs fast authentication attempts using ~37 hardcoded VIGIK keys, dumps the card, and can simulate or clone it.

Why

VIGIK is a widely deployed intercom/access control system in French apartment buildings. It uses MIFARE Classic with a known set of keys. This mode automates the entire VIGIK attack chain — from key discovery to cloning — entirely on-device.

How

1. SEARCH: Scans for MIFARE Classic cards
2. READ: Attempts authentication with hardcoded VIGIK keys, reads accessible sectors
3. LOAD: Loads captured data for simulation via JSON schema
4. EMULATE: Simulates the captured card

The mode uses a terminal-style UI with cursor positioning for status display.
