Hi all,
I've been playing around with NFC cards for a bit and managed to get the keys for a specific card of mine using miLazyCracker: https://github.com/nfc-tools/miLazyCracker/
However, after trying exactly the same attack again on exactly the same NFC card the crypto1_bs tool keeps showing me the message No solution found :(
My log:

And this is basically the loop where it gets stuck in. What could be the problem here?
