Mifare Commands

Hi everybody,

I'm playing with my Proxmark and a Mifare Ultralight Tag. I'm currently looking for Datasheet with all commands and what they stand for.

For example:

TAG 44  00   => I am an ULTRALITE Tag

Is there any list with this commands out there? I tried google, but didn't found a good answer.

Re: Mifare Commands

The ATQA is transmitted in reverse order. A small (and incomplete) list is available here wink

Re: Mifare Commands

Midnitesnake did an implementation of Ultralight UL and Ultralight C (crypto), you will find it in his fork.  I enhanced it a bit in my fork but I haven't push it either to the master.

Re: Mifare Commands

The commands are very similar to standard mifare, minus the authentication.

ULC uses DES crypto for authentication, but depending on the card config, you get limited access or read only, or read & write access.

There is a current PoC in git proxmark3-unstable, until I clean up the code.

Re: Mifare Commands

I refactored your code a bit, Midnitesnake.

added an hf mfu info command with manufaturing identification.
merged your dump commands into one
renamed some commads.

Soon, when this problem with making pull-requests it will be released.
