About:
Mfterm is a command-line interface tool designed for interacting with Mifare Classic 1k and 4k RFID tags. It provides a suite of commands for reading, writing, and manipulating tag memory sectors. The tool is essential for security professionals and hobbyists working on access control systems and RFID research.
Key Features:
  • Read and write data to Mifare Classic tags
  • Edit and manage access control bits (ACL)
  • Simulate tag interactions via emulation mode
  • Support for key management and authentication
Use Cases:
  • Auditing and cloning physical access control cards
  • Researching RFID security vulnerabilities
  • Developing and testing NFC-based applications
Alternatives:
  • mfoc – Mfoc is primarily used for nested key recovery and dumping card contents, whereas Mfterm offers a more interactive shell for ongoing manipulation.
  • libnfc – Libnfc is a lower-level library providing the hardware interface, while Mfterm is a high-level application built on top of such libraries for user interaction.
