Proxmark3 v4.16717 Released

This is the v4.16717 “Seven” release of the Iceman fork of the Proxmark3 firmware and client. Built from the commits since v4.16191, it focuses on new low-frequency brute forcing, tamper-tag support, Windows networking, and a wide range of stability and build fixes.

Highlights

  • Added an lf em 4x70 brute command to brute force partial keys on EM4x70 tags, expanding the Proxmark3’s low-frequency attack toolkit.
  • Added support for the NTAG213TT tamper feature, so the client can read and work with the tamper-detection function of these tags.
  • Added TCP connection support on Windows by reusing the BSD-style sockets code via Winsock2, letting Windows users connect to networked Proxmark3 devices.
  • Improved WSL2 (Kali Linux) usability: udev rules now assign group ownership and permissions, double-enumeration is prevented, and WSL detection is more robust with case-insensitive matching.
  • Added a data num command that converts between decimal, hex and binary using big integers (no hex-to-dec size limits) and flags prime numbers.
  • Added bruteforce functionality for HID facility codes and XOR key extraction for Guardall G-Prox II cards.
  • Updated the USB serial number to use the SPI flash unique ID and enabled the serial number from flash in the bootrom, improving device identification.
  • Fixed an infinite loop in SpinDelayUs()/SpinDelayUsPrecision(), a buffer overflow in AppendGraph(), and HF15 write/read when a UID is passed as an argument; also fixed the client build on Android.
