Spanish ID 3.0

[joanbono]

Hi all!

I'm from Spain and I own a new Spanish ID Card, which uses NFC.

So reading the specifications, it uses a CAN (Card Access Number) to read the owner information (Name, Surname, Photo, Birth Date and so on). So there's a photo of the card:

In the photo, at the right-bottom corner, the CAN appears (123456). I was testing with my PM3 and I was wondering if there is a command to extract this information.

hf search

I got really confused when I did the hf search command. The output gives my a different UID each time 😕

pm3 --> hf search

And next time:

Valid ISO14443-B Tag Found - Quiting Search

So it will be really nice to implement something to "attack" the card, or even a Lua script. I'll work on it, but I need some help and orientation.

Regards!! 😃

try hf 14b commands but use the PM3 Master instead of icemanfork. You might be able to read the tag data.

[joanbono]

No answer using the proxmark3-master firmware. The output is

proxmark3> hf 14b reader
no 14443B tag found

Reflashing to the icemanfork the output is:

pm3 --> hf 14b reader
 UID    : 16 D3 DC 10
 ATQB   : E1 F3 5E 11 77 81 A1

      Bit Rate: 212 kbit/s PICC <- PCD supported

So, it's quite confusing because the hf search in the proxmark3-master:

proxmark3> hf search
no known/supported 13.56 MHz tags found

But it works like I charm when I insert a blank chinese card instead the Spanish ID.
The hf search in the icemanfork works as shown in the first message.

[iceman1001]

did you try reading your tag?

[joanbono]

Sure! With the master fork, and says that there's no tag: hf 14b reader.

[iceman1001]

No, I didn't mean the "hf 14b reader".. there is some other read commands which tries to read tag memory

[osysltd]

@joanbono you can try to send raw commands to the tag according to

So reading the specifications, it uses a CAN (Card Access Number) to read the owner information (Name, Surname, Photo, Birth Date and so on).

By the way, just out of curiosity, please can you share CAN specification?

[joanbono]

Hi @iceman1001 , I don't get which command are you refering to... Sorry

@osysltd I've tried:

pm3 --> hf 14b raw 394496
pm3 --> hf list 14b
Recorded Activity (TraceLen = 12 bytes)

Start = Start of Start Bit, End = End of last modulation. Src = Source of Transfer

      Start |        End | Src | Data (! denotes parity error)                                   | CRC | Annotation         |

About the CAN, from the Spanish Police Webpage:

The CAN is a random six number digit which changes in every card. It serves as proof of possession of the DNI 3.0 when used with NFC technology.

There are 46 million people living in Spain, and there are only 1 million of possible CAN numbers...

[iceman1001]

as a suggestion, you should read up on iso14443b protocol, then learn how to use the "hf 14b raw" to send the right command with your CAN number. I'm curious of this CAN specification.

Somewhere in the specifications is the process of getting the data and how to process the data hidden.
Find it!

[joanbono]

UPDATE

I'm waiting answer from the tech-department, which has all the information about this card. I asked them for papers and implementations, and also how to take the stored information using the CAN.

[iceman1001]

Did your tech-department come back with some relevant information for you?

[joanbono]

Still waiting response. I'll ping them again tomorrow in the morning.

I'll keep you updated here.

[osysltd]

@joanbono if you have an ability to proceed with some transactions using your card with proxmark nearby, you can try to sniff communication and get more details meanwhile

[joanbono]

@osysltd I'll try, but it's an official document which only has use in webpages using the Smart-card chip. NFC is not fully implemented at the moment to be used to complete official documentation.

[joanbono]

I've been contacted by the Spanish police.

They say that they can't give me any information about the ID which is not published on their website.

I think I'm going to abort this mission, and perform a "black box" audit to the card 😆

Stay tuned.

[iceman1001]

Try to find the manufacturer. Also search for academic papers.
