Something very strange

Hi,
First, sorry for my bad english because I'm french.
I made a clone of an NFC mifare Cmlaissk 1K tag that I use to open my garage door.
I clone it (including the UID) on a "magic" changeable UID Mifare tag.
Everything worked fine during more than 2 years.
This morning the original tag works perfectly, but the cloned one does'nt work anymore.
I've tried with other clone tags that worked great before, same thing...
Do you have an idea regarding why, from one day, to the other, after  more than 2years working fine, thoses tags are not recognized ?
Thanks a lot for your help.
Kinds Regards

Re: Something very strange

Have you tried with another magic tag? 
Maybe your tag got corrupted and you just need to make a new clone.

Or maybe the garage door system has been updated?

Re: Something very strange

Hi, yes, I've tried with 2 other magic tags
I think too that the systme has been updated.
But whats should have been changed  ?
How  my tag could me made uncompatible with the new system ?

I've copied thaq UID and the content, what else can be detected by the new system as uncorrect ?

Re: Something very strange

some reader seems try to identify magic-cards ... there are not many possibilities to do so
but I have a friend - his gen1 magic works on two of three readers in his club  - the gen2 works on all three

My original tag works great, keys can have been updated on it by the reader ?

Re: Something very strange

yes, if the reader is connected to a backend system or if someone walked by and upgraded it on the spot.
Since you haven't revealed very much its a guessing game right now.

No, anti-passback doesn't seem to be activated, with the original badge, I can enter or exit many times without any restrictions

Re: Something very strange

Why not make a dump of your working tag and your clone,   maybe the community can help you looking at it?

Re: Something very strange

Hi,

It's me again.
After many tries, can't make it work...

Here are the two dump of original and cloned cards.
For me, everything is exactly the same, but the cloned card doesn't work anymore..

Just a thing, I use this modified nfc-mfsetuid to change the all block 0 datas (https://github.com/nfc-tools/libnfc/issues/282) and it'swritten :
"thus making them non-selectable by most tools/readers"
Could it be that ?

I'm completely desperate..

Thanks a lot for your help

Re: Something very strange

hm..  can you sniff the traffic between reader and the original card?  it looks like there is something else going on.
the two dumps are the same, from what I can tell.   

Just to eliminate a bad clone card, have you tried another one?

Re: Something very strange

You use your proxmark3 to sniff the traffic.  Since you are posting in a proxmark3 forum, I'm assuming you have one.  If not, is gonna be harder for you.

Salut yttrium
D'apres le dump de ta carte, c'est une carte HEXACT.
Ils ont mis a jour leurs platines il y a quelques semaines pour bloquer les badges chinoises.
Ils ont fait une pub citant que ca soit une mesure pour empecher le 'piratage des badges'

For the english speakers (sorry my english is not perfect neither)

OK, merci beaucoup pour cette info.
Aucun moyen de contourner donc...?

Et comment peuvent-ils la détecter si le con,tenu et l'ID sont identiques à la carte d'origine ?

Ils cherchent le tram de déverrouillage sur les cartes chinoises. Si la carte repond au tram, c'est bloqué.
Il faut trouver donc une carte magique qui ne repond pas au trams magiques.. assez difficile je penses...

In the meantime, I am thinking that a Chameleon Mini might be able to do the trick?

Re: Something very strange

If the system is actually blocking tags that respond to the magic commands, then I would assume the Chameleon Mini would work, as they emulate the Mifare Classic, without emulating the magic commands?

Since OP doesn't seem to have a device to work with,  neither PM3 nor Chameleon this thread becomes teoretical.

Salut yttrium
D'apres le dump de ta carte, c'est une carte HEXACT.
Ils ont mis a jour leurs platines il y a quelques semaines pour bloquer les badges chinoises.
Ils ont fait une pub citant que ca soit une mesure pour empecher le 'piratage des badges'

For the english speakers (sorry my english is not perfect neither)
This brand of card manufacturer updates their systeme some weeks ago, to block chinese magic cards.


OK, merci beaucoup pour cette info.
Aucun moyen de contourner donc...?

Et comment peuvent-ils la détecter si le con,tenu et l'ID sont identiques à la carte d'origine ?

Ils cherchent le tram de déverrouillage sur les cartes chinoises. Si la carte repond au tram, c'est bloqué.
Il faut trouver donc une carte magique qui ne repond pas au trams magiques.. assez difficile je penses...


Quand tu dit assez difficile, ça veut dire impossible et je dois définitivement oublier l'idée de chercher et d'accéder à mon garage ou bien j'ai quand même une chance ?

Re: Something very strange

Copy the card to a gen two tag or fuid one time write tag so the reader doesn't detect its backdoor. I recommend

Re: Something very strange

Bonjour, il éxiste des badges que ne répondent pas au magique.

Et certains badges badges répondent au SAK 08 alors que l'original retourne 88.

Si tu modifie le SAK dans le bloc 0, le badge magique retourne toujours 08.

Hello, there are badges that do not respond to magic.

And some badge badges respond to the SAK 08 while the original returns 88.

If you change the SAK in block 0, the magic badge always returns 08.

Re: Something very strange

Its because of the anti-cloning features in the Vigik system.

You need to follow @slmann101 earlier post where you get a FUID (write-once uid card) or Gen2 to get by.
Vigik reader will detect a Gen1A.
