MIFARE DESFire®MIFARE DESFire® EV1 remain the industry standard for ultra-high security badges. As of yet - the MIFARE DESFire® EV1 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® Compatible UID Modifiable Emulator Card is a card that emulates a MIFARE DESFire® card, allowing you to set a custom UID.

This card will allow for bypass on systems that authenticate based off the UID.

There are two variations of card, 7-byte UID and 4-byte UID.

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

Badges come in a white PVC card format.

Hands on with the MIFARE DESFire® Compatible UID Modifiable Card

Modification of the UID is incredibly simple, thanks to a raw 14443 command.
Using your Proxmark 3, you can issue the following command:

 

hf 14a raw -s -c 02 00 ab 00 00 07 xx xx xx xx xx xx xx

 

Where xx xx xx xx xx xx xx is your target UID.
For 4-byte cards, your UID will be 4-bytes, for 7-byte cards, the UID will be 7-bytes.

Likewise, you can also use set the UID on Windows/MacOS/Linux via LibNFC and a LibNFC compatible reader/writer.

Launch the tool pn53x-tamashell

 

$ pn53x-tamashell

 

Then, use the following commands to select the card, and then write the UID.

> 4a 01 00
> 42 02 00 ab 00 00 07 XX XX XX XX XX XX XX

Where xx xx xx xx xx xx xx is your target UID.
For 4-byte cards, your UID will be 4-bytes, for 7-byte cards, the UID will be 7-bytes.

IMPORTANT:

The UID of MIFARE DESFire® Compatible UID Modifiable tags is comprised of two parts: the UID itself, and the BCC. The BCC is a checksum value calculated from the UID. If the BCC is incorrect, tag will be rejected by the reader.

Most RFID tools, such as the Proxmark, LibNFC, MCT etc automatically calculate the BCC when the UID is modified. If you are modifying the UID by hand, it is vital that the BCC is correctly calculated.

Lab401 cannot provide support or refunds under any circumstances for cards that were 'bricked' due to incorrect UID/BCC configuration.
