Re: Sniffing / Dumping a Desfire Card?

for more details with regards to desfire,  try  the  hf mfdes info command.
For desfire normally we would need to enumerate all AID's and try to see which can be read.

from that point right now, i cannot do anything with that card, right?
not dumping the card to a file
not getting the keys
not cracking anything
not cloning

am i right?

best regards

Re: Sniffing / Dumping a Desfire Card?

for now you cannot "dump" a desfire card. desfire cards are very diffrent vs mifare classic / ultralights ...
for recap:
- mf classic is sector / block oriented with crackable keys -> cloneable
- mf ultralight ev1 is block oriented with sniffable PASS -> cloneable
- mf ultralight c is block oriented with mutual auth with 3DES key -> cannot get key with sniffing

now for desfire:
- mf desfire is kind of file system oriented with applications and files within the applications with 14 diffrent keys for each application
-> mutual auth with 3DES or AES key -> cannot get key from sniffing
-> if the communication between reader and card is done in plain mode you can sniff the data, that the terminal reads from the card

your posted sniff is lacking the reader / terminal side,
can you post a better snoop?
