mifare classic 4k problem when reading some sectors

oscuro · 2017-11-19 11:54:16

Hi, I've tried several firmware versions, right now I have this image

My card is the following

With this firmware I get the following with hf mf mifare, with other firmware and always got points ............

With another firmware

I have several sectors that I can not find the password to read them, sector 1, 6 and 7

How can I read the blocked sectors? Thank you!!

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

Hello, here other firmware:

result:

what's my problem?

Thank you!

Isn't that obvious?

Card is not vulnerable to Darkside attack

Tag isn't vulnerable to Nested Attack

oscuro · 2017-11-20 19:41:52

So, can not I read the blocked sectors in any way?

piwi · 2017-11-20 22:06:03

You have some valid keys. Try hf mf hardnested.

oscuro · 2017-11-20 23:07:23

Hello!! I have tried the following command:

hf mf hardnested 0 A FFFFFFFFFFFF 4 A

Where is that password from? How can I use it? forgive me but I'm a novice

Thank you for help me!!

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...............

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!

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.

Sorry to seem lazy, I just found the keys that I was missing! the following text has been very useful to me!
