ACCESS THE PHYSICAL SUBSTRATE. This Android terminal allows for the reading, writing, analysis, and cloning of MIFARE Classic RFID assets. It serves as the bridge between the MontiNode Network and physical access tokens.
- Asset Extraction: Read data from MIFARE Classic tags (Sectors & Blocks).
- Payload Injection: Write data to tags block-wise.
- Token Replication: Clone tags (Dump-to-Tag) or Clone UIDs (requires "Magic" Gen2/CUID cards).
- Dictionary Attack Vector:
- Utilizes a
keysfile (Dictionary) to attempt authentication against all sectors. - Note: This is not a brute-force cracker. It is a key-mapping tool.
- Utilizes a
- Sector Analysis: Decode & Encode Value Blocks and Access Conditions.
- Data Visualization:
- Highlighted Hexadecimal Output.
- 7-Bit US-ASCII decoding.
- Diff Tool: Compare two dumps to identify changes in the data structure.
- Hardware Bridge: Supports external NFC readers (e.g., ACR 122U).
This tool CANNOT crack unknown keys via brute force. The protocol is too slow. To interact with a secured tag, you must already possess the keys.
- Recommended Extraction Vector: Use Proxmark3 or LibNFC hardware to recover keys, then import them into MONTI-NFC.
- Device Support: Not all Android chipsets support MIFARE Classic. Check the Incompatible Device List.
- Magic Tags: To write to Block 0 (Manufacturer Block/UID), you need Gen2 (CUID) tags.
- Gen1 (UID) tags require a special wake-up command sequence not supported by standard Android APIs.
Uninstalling this application will PURGE all saved dumps and key files. Ensure you export your state-data to the MontiNode server or local storage before removal.
You cannot read a sector without the correct Key A or Key B.
- Use the included
std.keys(Standard Default Keys) for low-security targets. - For high-value targets, crack the keys using external hardware.
- Import your keys into the Edit/Add Key File menu.
- Select "Read Tag".
- Choose your Key Dictionary.
- Map the keys to the sectors. The app will attempt to authenticate every sector against every key in your list.
- Once a dump is secured, use "Write Tag".
- Select the dump and the target tag.
- WARNING: Ensure Access Bits (Trailer Block) are correct. Writing bad Access Bits will permanently lock the sector (Brick the tag).
