Creative ways for securing mifare classic 1k

Hi there, I want to just share the securing things applied on these cards. One of my customers has bought that mifare based framework developed by an italian company for his micropayment transactions. They used to sell prefilled cards they calls "preformatted" that don't have rig association or credit loaded. I've dumped those prefilled cards and all have the same mifare key pairs on all sectors. The sector 0 blocks 1 and 2 are the same on all of those cards, the entire sector 1 is filled with ascii coded developers address and obviously is the same on all cards. In sector 2 block 0 there are a couple of byte pairs that change between cards. Sector 3 to 14 are all 0 filled. In the sector 15 there is a byte sequence that vary drastically between cards, it's 18 byte long, occupy the entire block 0 and the first 2 byte of block 1.

There are some dumps:

The b key from sectors 4 to 14 seems a simple bitwise operations but the system only use sector 2 and 3 for storing data.

For now I don't want to look how the credit and so are encoded because my curiosity was captured by that  sector 15.
Seem some sort of hash of uid, but 18 bytes? Hash + crc or checksum?

The next try will be a cloned card with changeable uid, we'll see..
A fact is that security system make sniffing useless.
What do you think about?

Test done, the reader was fooled by gen1 cards. I've made ten card with the same uid, all of these was accepted, I've load different credits in some of those and the reader right differentiate every card with the right credit. No blacklist, no master db, only signature check against the uid.
Probably the reader reads the card uid, read the sector 15 signature, recalculate uid based signature in their mcu and compare the result with sector 15, if there is a match the card is accepted.
Forgot to mention in my previous post, the sector 0, 1 and 15 was never wrote by the reader.

Re: Creative ways for securing mifare classic 1k

Just for discussion:
Why do you think that their security system makes sniffing useless ?

On a side note: If i was to build a system, I would also add a one time key (OTK).
Lets say you have a card with ID : 11223344 and a value of 100, then add a OTK of 92837846
You could clone that to the UID cards and have x clones.
Next time any of the cloned cards is presented, I could then read the ID : 11223344 and the OTK 92837846, if both matched what I think they should be, then I will accept the card.  During the transaction I would then send the "next/new" OTK to the card : 56292756 (random)
At this point all other clones would become invalid and fail as the would still hold the old OTK.

So each clone would need to be re-cloned every time ONE had been used.

Re: Creative ways for securing mifare classic 1k

hm...  I used to think that was a good idea until someone explained that, the first one who uses the card  (original or clone) gets the next token.   Ie, if the cloned card is used first then it gets the next valid token aswell...which effectivly means your protection successfully locked out the owner.

Re: Creative ways for securing mifare classic 1k

@iceman, yep, that was actually my point.

If the owner cloned to give to his friends, then it wont work very well and will force there to be only one card in use.
If the owner did not know someone cloned it, then next use it would fail and they would report it (now known it was cloned).  So the vendor would know to cancel the card and re-issue to the owner.
ie. similar to the way HOTP uses the hash based on the next counter ID.  If the OTP (one time password) token was stolen/leaked out then the owner WILL know.  With TOTP tokens, if they leak out both the hacker and the user can still use it and the user may not know.

back to the OP (dont want to hijack the thread).

Thank you for your reply,
I think that because the main security enforcing is stored in payload, with an unknown algo, no crypto1 based. The card dumping is a straight forward thing, with nested auth. There's no challenge response to sniffing for. The vendor cards btw seems all old RNG based. So what I can do with that log? The developers was conscious about the security weakness of crypto1 and did not use it for main and only security system. Also a truth is the developers has falls with uid chinese cards..

About the OTK things, in the installation there are a bunch of readers, for various services, and all of these are rigorously offline. For token generation we need a seed that is the same on all of the readers ,that implies some sort of syncing thru readers. Also the reader seems don't store nothing, its rely exclusively on cards storage. I know this is a weakness but is also a necessity, for more easy installs and because one can have multiple installations in different town that share the credit.

So the reader use a kinetis 20 mcu, no funny stm32 exploit.
Without going online one can only cut out gen1-2 cards with a fw checks, but remains vulnerable to emulation and fuid but seems there are more difficult to obtain
