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

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

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

LED Indicators

LED	Meaning
Complex terminal UI	Uses debug output for status rather than traditional LED patterns

Button Controls

Action	Effect
Various presses	Trigger different functions in the UI
