Cloning MIFARE Classic with PM3 Iceman

Hi, the company that deals with waste collection provides us with a card (credit card format) to open the various containers (plastic, paper, organic etc.) the card should be a mifare classic, I would like to clone it on a key fob because 'it’s more convenient, I have the PM3 easy with the Iceman firmware, but I don’t know where to start… who can help me? Thank you… :slight_smile:

Do you have the PM3 client up and running?

You can check with hf search

Do you know if the target fob is a magic tag?

Next you would try hf mf auto on the source card

You may need a different target fob then, depending on the system

Some parts of the tag can’t be written to by default, you need a magic chip to be able to clone the whole card

There is a small chance however that whatever system it is doesn’t use the bits that you can’t copy at the moment

so let’s try, maybe I’m lucky… garbage collection system should not be a safe… perheps they did not use the hardcoded part… please tell me how to proceed, i’m a dummy regarding PM3… thanks

Have you done this part?

I’ll do now… hold on

after 25 seconds eventually ii says
Card is not vulnerable to Darkside attack (doesn’t send NACK on authentication requests).

[-] No usable key was found!

Does it keep going after that?

Try an hf mf mad just for funsies

Auth error
[!] error, read sector 0. card doesn’t have MAD or doesn’t have MAD on default keys

Can you post a picture of the ending of the output from hf mf auto

That’s interesting, I don’t think I’ve ever seen that particular error.

You could try repositioning the card on the PM3, trying to get better coupling, as well as making sure the PM3 isn’t over a conductive surface which could cause interference

If none of that works I think you’ll be stuck with trying to sniff the reader, here’s a little more info about that:

thankyou… I’ve tried to reposition the card in the meantime, response is always the same… no luck,., now I have to wrap up, I will read what you suggested and in case I’ll ask for help again… thanks again…

Next suggestion is:

  • run autopwn with a dictionary

if that doesn’t work you will need to sniff the traffic to extract a key or two that way.

and of course, always make sure people are on latest source…

Hello… I need some more explanation please, I’m on my first experience with PM3 and hf cards, I only used it once to dump/restore an lf t5577 fob…nothing more :slight_smile: what do you mean by “a dictionary”? where can I get a basic knowledge text to learn something more about PM3 and related firmware?
