Unable to read 2 Sectors on MiFare Classic 1k

[White-waluigi]

I have a MiFare Classic 1k card that I would like to read out. Unfortunately, mfoc seems unable to read out 2 sectors. I have already tried mfoc-hardneseted, but with the same result. The card seems to yield a Key A and a Key B but they cannot be used to access sector 01 and 02. What does this mean? Does the card use a nonstandard Key and therefore mfoc can't crack it? Is it a later revision with vulnerabilities patched out? I am using a PN532 on a raspberry pi. I am using the latest version of libnfc compiled from the repo, same with mfoc
