Problem Authentification MF Classic 4k

NeiJPass · 2014-05-14 20:53:21

I need your help.
I have a Mifare Classic 4K card that I can not read it. Just let me read the UID anything else but get the following message:

I tried to snoop and not completely reads the tags

please!

tried the "hf mf mifare" ?

NeiJPass · 2014-05-14 21:17:39

I've tried but it takes more than 30 minutes. that's good?

iceman · 2014-05-14 21:55:54

the flashing red stop at 42 minutes
the bootrom version has to do?
someone who has been passed with a 4K and MIFARE CLASSIC has managed to read it, can explain as has removed the authentication card

NeiJPass · 2014-05-15 18:06:46

There is some brute force method?

app_o1 · 2014-05-16 04:31:48

You obviously are not using a recent revision.
I had similar issues on old revision.

Can you try with latest rev and let us know if it works better.

Also, do you know at least one Key ?
you could skip "hf mf mifare" and try :
"hf mf nested 4 0 A a0a1a2a3a4a5 d"
Replace a0a1a2a3a4a5 by whatever your Key is.

NeiJPass · 2014-05-16 14:13:52

Thank you very much for your help. I will change to the new version. The truth is you're asking authentification in all blocks. I will comment on results

NeiJPass · 2014-05-16 20:49:36

change:

iceman · 2014-05-16 21:39:19

the "can't select card" makes me wonder if your antenna does work? or is it really a 4k mifare s70 card?

thefkboss · 2014-05-17 10:01:27

this happen because the card is the new mifare card.
the only way to crak is sniffing

NeiJPass · 2014-05-17 10:06:09

Thanks TheFKBoss
I thought so
Is there any method, for example sniffe sticker and record the data in its memory and then read the sticker? data when the card is recharged?

app_o1 · 2014-05-17 14:01:02

That also happens on recent rev when the card is too close to the antenna. Try to keep 1.0 cm ~ 1.5 cm distance between the antenna and the card.

By the way, in my case, the nested attack on mifare 4k starts, works for 2 min but never finishes. It always freeze and I have to unplug/plug the proxmark otherwise it is not responding.
With that particular card, I get 49 "Found valid key:xxxxxxxxxxxx" and then it freezes.

Hello updating pm3 bin I read with "HF MF URDCARD" and what is my surprise:

iceman · 2014-05-18 10:31:39

the "HF MF URD*" commands is for ultralight cards..

or are you trying to use it to read your 4k card?

NeiJPass · 2014-05-18 10:45:07

If put that card not recognized thought it was another type of card. ultralight and reads blocks not read with Classic 4k

No more ways to crack the authentication? Brute force is very difficult?

thanks

pusinato · 2014-06-02 10:56:38

I have tried the new 0.0.2, 0.0.1 and a lot of the other revision, it halts when hf mf nested 4kb cards
the card is mifare classic 4k
can someone write a few commands so i can succed to pull out the keys

app_o1 · 2014-06-02 15:37:01

You don't get any result after you start the nested attack ?
It does not even "work" for a few seconds ?
