So I'm trying to get my head around ultralight EV1 cards and am have some questions for the hive mind.
I understand that the EV1 cards have a key, and this can be easily sniffed from the reader, and that's fine. I can then use this to put it into a 'hf mfu dump k xxxxx' command and then head onto either clone it to a new card or simulate it on the prox itself. This works great, huge props to Iceman for his great fork!
My question is, now im away from the reader, as it was a hotel i was staying in, can i obtain this key any other way?
I have read about the 'hf 14a raw -c' commands but am getting slightly confused.
is there a command to run through a set of default keys like the hf mf fchk for mifare classics?
Appreciate any help anyone can give.
Below is the output from the traffic sniffed between the card and the reader for reference.
