Topic: nfc-mfclassic not able to read block

Hello,
Recently I tried to read Mifare classic cardusing nfc-mfclassic command.
This tool was able to read nearly all card except 1 block

So I thought that key responsible for this block was changed and I run MFOC
MFOC found all keys and did memory dump. When I looked at output logs the same blok is missing.

Any ideas how to solve this issue ?

Regards

Is it possible that this block is hidden ? (is such parameter available on mifare classic)

Is there any other linux app that allow read from mifare classic card (completely or specific sector) ?

Regards

Hi,

Its possible to have some locked blocks : have a look to access bits (you will need to understand how it works...).
Unfortunately, its also possible to have some bad reads on access bits.
