Users of this forum, please be aware that information stored on this site is not private.
I have used a couple times the hf mf sniff command to later on decrypt the keys with mfkey64, but for that I need the proxmark3 connected to the computer through cable or the bluetooth module, which I don't have.
I saw the HF_14ASNIFF standalone mode, which sniffs 14a traffic and saves it to flashmem, so I can plug the proxmark3 into a battery, sniff the data using the standalone mode and afterwards plug it into the computer to retrieve the data.
Here are the commands I use after having sniffed the data
mem spiffs dump o hf_14asniff.trc f trace.trc
trace load trace.trc
trace list mf 1But instead of getting the usual long chunk of communication reader/card, it only spills out 2 blocks, one for the tag and one for the reader.
