Not sure what has changed in the Proxmark firmware, but not quite working the same. hf iclass dump, sometimes does not accurately get the CSN and CC used for Authentication. Other times it fails to execute the procedure to dump the card, or a correct MAC is diagnosed as authentication failure. However, if a MAC is corrected calculated, card contents ca be dumped with hf iclass replay <MAC> It could be down to the antenna? as I am Using the RyscCorp HF Antenna. Requires further testing!
