Mifare 1K - Strange Key Problem

Hi Folks,

I have a Mifare card where all the keys are known (Or so I think)

I can authenticate successfully on sector 0, 1 and 2. However in sector 2 I have an odd problem. I can read Block 8 and 9. However I cannot read block 10 or 11. It won't authenticate. I've tired the A and B key to no avail. It seems odd as the same keys are used for 8 and 9, and I can read these fine.

Hardware: ACR122U
Software: Bundled Software

On a side note, is there any good Windows / Linux software for easily reading cards? The bundle software with my reader is a little clunky.

Any insight?

Many Thanks,

ironclaw.

Hi dxtno. Thanks for the reply. I tried MiCmd originally. I can't get it to read. It will connect, and authentication but then errors when one tries to read.
