Mifare Ultralight Clone

Hey everyone,

First post here so bear with me... I've completed my intro post and have recently obtained a proxmark3. I am still learning how to use the device and I think I've started with the most challenging card to clone.

I am using my hotel key which is an Ultralight EV1 (48 bytes). I am trying to see if I can clone my card and develop an understanding of the card's settings.

I have tried several different methods to obtain information from the card and learned that it is protected by a password. Common default ones do not work. I have used the sniff command to obtain the activity on the card and believe I have identified the hex data where the password is stored (based off reading other posts and information posted by Iceman).

I found this:
208464 |  216688 | Rdr | 1b 9e 97 6d 68 68 8c
                   ok  |  PWD-AUTH KEY:  0x9e976d68

Since I have this information - is this the password key or do I need to somehow decrypt this data?

I tried to do a dump command using variations of the above key and converting the bin file to an eml file. However, when I tried to load the eml file (using eload command) proxmark says the file is not found or locked "-u.eml".

Does anyone have any suggestions or places I can read up a little more on this process? I haven't had much luck elsewhere.

Re: Mifare Ultralight Clone

if you are on latest RRG/Iceman ,   since we are doing the cliparser change there is mismatch with "hf mfu eload" right now.
You will need to use the  "hf mf eload -h"  instead to load an ultralight dump to the emulator memory.

You would use the pwd when running the dump command to get a complete dump.

Hey Iceman - that worked!

Thanks for your help. I did the 'hf mu' command and got it to simulate.

Now I am just working on getting it on to a magic card instead of simulating through the device. /
