Proxmark3 v4.20142 "Blue Ice" Released

Version 4.20142 “Blue Ice” of the Iceman fork of the Proxmark3 firmware and client is here. This release brings new attacks, fresh tag support, and a long list of reliability fixes across the LF and HF stacks.

Highlights

  • Added hf iclass trbl to run tear-off attacks against iClass cards, plus new special legacy config cards and a simulation function in hf iclass legrec, expanding the toolkit for iClass research.
  • Added lf hitag htu support and lf em 410x clone --htu to clone an EM410x ID onto Hitag Mu/8265 transponders, opening up a new generation of LF tags.
  • Added hf mfu aesauth for MIFARE Ultralight AES authentication, with hf mfu info now correctly identifying UL EV1 AES 50pF parts.
  • Changed hf mf autopwn to detect static encrypted nonces and honor user cancel during key checking, with a new option to use the SPI flash dictionary and a custom suffix.
  • Added hf seos sam for HID SAM SEOS communications and improved trace list -t seos to annotate ISO7816, strengthening SEOS analysis.
  • Added hf 15 slixprotectpage and initial support for ST25TN tags with signature verification, broadening ISO15693 coverage.
  • Moved flash-stored key dictionaries (MIFARE, iClass, T55xx) and configurations to SPIFFS files and extended MIFARE key storage to 4095 keys for far larger on-device dictionaries.
  • Fixed DESFire D40 secure channel crypto and hf mfp info signature checks on 4-byte UID cards, plus Wiegand decode no longer drops the first bit.
