You may consider upgrading your ancient firmware (it is dated 2015) or repeat hf mf nested until you succeed.

Isn't that obvious?

Card is not vulnerable to Darkside attack
Tag isn't vulnerable to Nested Attack

You have some valid keys. Try hf mf hardnested.

Re: mifare classic 4k problem when reading some sectors

Read the forum on samburner post.

You got to do a command to check which block is the default keys.

From there, use that key to solve it.

Keep reading. I remember I wrote a full command set somewhere on the forum.

'hf mf hardnest' to see the options for the command...............

Re: mifare classic 4k problem when reading some sectors

With the command you had asked to crack the A key of block 4. As a result of the command you have found the A key of block 4.

For sector 6 and 7, how is the command hardnested?

What is the command to read a complete dump?


Can you explain what a block is and what is a sector? I think I messed with that!

Thank you!

Re: mifare classic 4k problem when reading some sectors

As usual, read the helptexts.   There are plenty of samples in how the command works.   
Next,  search forum for hardnested threads,  you be surprised how many are asking the same question...
Next,  read a datasheet for the card you trying to analyse. There are plenty at the files section...

Next,  if all above failed,  write a post.

Don't be lazy.
