ACR122U vs 1K Mifare – few days of dumping and.. nothing
Hello
I'm trying to clone 1K mifare card. I spend a lot of time on this, but without effect.
I’m working on ACR122 and Kali Linux 32 bit.
I using: mfoc –P 500000 -0 keydump
And here are my results:
First try and first error:
Sector: 12, type A, probe 4697, distance 33295 - ..Violation of memory protection
Ok, I'm not surrendered and I tried again.. Few days later, after 47829 probes, next error:
Sector: 12, type A, probe 47829, distance 33786 .*** Error in ‘mfoc’: free(): invalid pointer: 0xb63e2008 ***
Did I should try again and leave it for a few days again?
Or Am I doing something wrong?
Sorry for my English.
Please help.
Dawid.

You do know that you are posting in a dedicated proxmark3 forum?
I suggest libnfc forum / mfoc issues on github for your question.

I know, but I think it's not a device fault.

The proxmark3 has its own impl of the darkside attack and nested attack. As mentioned mfoc questions better asked in issues on its github repo
