Newbie with a question: Protection against cloning

[Harald]

Hey,

it is not so long ago that I got my first implant, therefore I still have some questions regarding protetion against cloning RFID cards.

I currently stay in Helsinki for half a year where they have RFID cards as longterm tickets for public transport (HSL). I would like have my card cloned to my xSIID implant but I should discuss the details regarding that better with HSL.

My actual question is: If they transfer my card to my implant, they probably will protect it against further cloning and other manipulation (like every commercial RFID card is). But my longterm ticket will expire eventually. Is there a way to remove the ticket information when I dont need them anymore without formatting my implant?

(Sorry for the probably weird english, not a native speaker)

Do you even know if the XSIID is compatible with the chips used by HSL? They might use some other format of chip entirely.

If they’re using chips with protection like that, it’s probably a cryptographic chip, which likely means that the XSIID isn’t compatible.

At a minimum, I don’t believe there’s any real copy protection possible with plain tags like the XSIID, you can protect it from writing, but that would stop it from working as a keycard too, not just block copying

Your English is awesome

I would reccomend you download TagInfo and scan your HSL card.

And let us know what it says in the IC Info page

How to share NFC chip data via TagInfo app

TagInfo is an app made by a chip manufacturing company called NXP. It does a decent job of determining the type of chip it’s talking to and fully scanning any accessible memory into a scan report. It also makes sharing information gathered easy, which makes diagnosing problems or answering questions about specific NFC tags one might have much more efficient.

Good candidate for conversion? Methinks not - or perhaps yes

Amal, here’s the inside of my bus card, seen against a 1.5 kW projector shining through it. The blob on the upper right (dim. 8.1 x 5.3 mm) is a DESfire EV1, and the antenna goes all around the card (i.e. it’s not a mini card thing). [image] Does that tell you anything about the chances of converting it?

[Harald]

Thank you for all your replys.

It was an interesting threat. So the most important things to check if the HSL card is compatible with XSIID the card type and the capacity?
Or was the capacity just important for the new flex antenna?

If Rosco wanted his actual bus card implanted then I fear it wont be possible to just load the HSL card onto the XSIID.

@Pilgrimsmaster

The IC type is MIFARE DESFire EV1 (MF3ICD21). What information can one get from this?

[Pilgrimsmaster]

@Harald

check if the HSL card is compatible with XSIID

unfortunately

@Harald

The IC type is MIFARE DESFire EV1 (MF3ICD21)

It’s not.

Here’s the bossmans explanation

@amal

Typically desfire ev1 chips that leverage application file space protected by 3des cannot be cloned. You’d need to explore conversion.

Rosco got his converted and didn’t have any luck with his, That’s not to say that you won’t with yours, so if you are still interested, it might be worth sending a transit card for conversion.

I started going down that path also, buts it’s just not something I use alot, so I didn’t pursue it further.

Public Transport Conversion by [image] Feasibility Throughout the world There are many and varied Public Transport Infrastructures utilising a wide range of RFID technology, fortunately for some, there are some older / less secure systems such as Mifare Classic (There are a few examples here on the Forum) and fortunately for people with access to those systems, Dangerous Things [image] have some “off the shelf options” .

Ah, okay. Thats unfortunate. But anyway, thank you for your help!
