key never change

[NotsOverflow]

hello, i use "mfcuk -C -R 0 -v 3 -o dump" to try to find a key with the last version of mfcuk it seams not to work cause the key is always 000000000 in the verbose output

Let me entertain you! uid: d3e215f3 type: 08 key: 000000000000 block: 03 diff Nt: 3351 auths: 9997

is it normal? or do i have to change something in the source code to make it change the key? thanks in advance.

(don't forger to get uid-changable cards :p )

[ilfuriano]

Which version of mfoc and libnfc did you use?

[NotsOverflow]

@richardjuan i have the same issue, are you confirm mfcuk is running ok even the key never change?

[NotsOverflow]

@shoaly yep, everything is ok. btw some reader implementation ( garrage door, buildings entry ) look like they don't care about what's in the key and only look for the uid :)

@richardjuan How long did it eventually take?

@SamDecrock Hello, at the end have you successfully crack the card?

@ChunJyeBehBeh I did using the mfoc hardnested fork. I made a write up about it.
