MIFARE DESFire® Compatible Modifiable UID / ATQA / SAK / ATS / APDU

MIFARE DESFire® remains the industry standard for ultra-high security badges. As of yet - the MIFARE DESFire® remains invulnerable to all channels of analysis.

The inner workings of the MIFARE DESFire® cards remain under NDA lock and key, making it incredibly difficult to reverse engineer the protocols.

Lab401's MIFARE DESFire® EV2 Compatible Modifiable UID / ATQA / SAK / ATS / APDU Card emulates a MIFARE DESFire® card, allowing you to set not only a custom UID, but also customise the ATQA, SAK, ATS and APDU values.

This means you are able to modify the card to simulate multiple types of DESFire® cards (EV1, EV2, etc).

Please note, this card does not emulate any other MIFARE DESFire® features.

Badges come in a white PVC card format.

  • Badges come in a white PVC card format.
  • Proxmark 3 compatible

Hands on with the MIFARE DESFire® EV2 Compatible Modifiable UID / ATQA / SAK / ATS / APDU Card

Changing the UID
Using your Proxmark 3, you can issue the following command:

Change UID Command
hf 14a raw -s -c -t 1000 cf00000000CD00<uid>

Example: Set UID to 11223344556677
hf 14a raw -s -c -t 1000 cf00000000CD0011223344556677

Setting up ATS:

Setup ATS Command
hf 14a raw -s -c -t 1000 cf0000000034< Length > < ATS > * The length is set to 0, indicating that ATS is not sent
* When SAK is 20, 28, be sure to set ATS, otherwise you can't read the card.
* The last two digits of ATS are CRC, which cannot be counted into the length

Example: Modify ATS to 060675781028002F0
hf 14a raw -s -c -t 1000 cf000000003406067577810280

Setting up ATQA and SAK:

Setup ATQA / SAK Command 
hf 14a raw -s -c -t 1000 cf0000000035<ATQA><SAK> * Note that ATQA is inverted on the Proxmark

Example: Set ATQA to 00 44 and SAK to 28
hf 14a raw -s -c -t 1000 cf0000000035440028
