Mifare Classic Plus - Mfoc + Hardnested + mfkey32v2 Attack Implementation for PN532+PL2303

Follow the steps in the link below to register your reader and UART on your computer:

How to Use PN532 on macOS with libnfc, mfoc, and mfcuk

Make sure you have the following:

• PN532, PN532 BLE, or PCR532 Reader
• USB Cable
• macOS 10.12 or later

The PN532 and PCR532 Readers from MTools Tec use the CH340E USB-to-serial chip. To communicate with the reader, install the USB serial driver:

• Download the driver from the CH340G USB Serial Driver URL. This driver is also included in the reader package.

• Open the CH34xVCPDriver app and click the install button.

• Reboot your computer after installation.

• Test the installation by running this command in your terminal:

  ls /dev/tty.*

• You should see something like /dev/tty.wchusbserial1410. The port name may vary.

1. Install Homebrew if you don’t already have it.

2. Run the following commands to install and link libnfc:

   brew install libnfc
   brew link libnfc

3. Plug in your PN532 or PCR532 Reader. Your system should automatically detect the USB serial port. Run nfc-list to check if the reader is recognized:

   nfc-list

   You should see output like this:

   ➜  ~ nfc-list
   nfc-list uses libnfc 1.8.0
   NFC device: pn532_uart:/dev/tty.usbserial-2140 opened
   1 ISO14443A passive target(s) found:
   ISO/IEC 14443A (106 kbps) target:
       ATQA (SENS_RES): 00  04
       UID (NFCID1): 01  02  03  04
       SAK (SEL_RES): 08

If you encounter the error Unable to open NFC device: pn532_uart:/dev/tty.wchusbserialxxxxxx, follow these steps to modify the libnfc configuration:

1. Open the libnfc configuration file:

   sudo nano /usr/local/etc/nfc/libnfc.conf

2. Make the following changes:

   • Set allow_autoscan = false

   • Set allow_intrusive_scan = false

   • Update device.name to:

     device.name = "pn532_uart:/dev/tty.wchusbserialxxxxxx:pn532"

3. Save the file and exit. Run nfc-list again; the issue should be resolved.
