Check Key with Mfcuk #88

Open cenzo85 opened 11 months ago

Hi all, I want try to use this tool in order to recover a key form a Mifare card.

My card have the first 10 sector setted with key A / B "ffffffffffff"

So, now using the comnand: mfcuk -C -R 0 -d ffffffffffff -v 3

I'm aspecting to receive an immedite confirmtion of the key... BUT, the tool not identify the key and continue to execute an infinite check. The log write me:

`

Let me entertain you! uid: 8f008a4b type: 08 key: 000000000000 block: 07 diff Nt: 1 hit4: 0 auths: 7


Let me entertain you! uid: 8f008a4b type: 08 key: 000000000000 block: 07 diff Nt: 1 hit4: 0 auths: 8

`

In my mind I would aspected the the key will change every time..
But actually I see that the system check every time the key 000000000000 And this is confirmed because no key are found

I have note the also by using:

mfcuk -C -V 1 -d ffffffffffff -v 3

the system respond me: Key A sectors: 0 1nfc_initiator_transceive_bytes: Mifare Authentication Failed

Could some on help me to undestand how it work ?
