nfc-mfclassic probleme Key B

**jfab66** · 05/11/2019, 13h45

Bonjour

j'ai un problème de clonage du badge NFC lors du transfert via la manip avec 'nfc-mfclassic'

Code :

Auth with all sectors succeeded, dumping keys to a file!

Mais quand je veux copier les données de cette clé NFC
- UID est bien clonée
- une partie des données sont clonées
- SAUF !!! -> toute la partie comprise dans les secteurs 8 à 14 car la Key B [415a54454b4d] n'est pas prise en compte

voici la partie d'origine

je ne sais pas comment préciser dans 'nfc-mfclassic' pour inclure la valeur de la KEY B
j'ai essayé plusieurs manips sans succes :

je précise au post précédent que j'utilise des badges avec UID modifiables et que le clonage a été possible via une application Android avec un téléphone NFC.
Mais
n'ayant pas de téléphone NFC, je voudrais faire la meme manip avec Kali Linux et le lecteur NFC ARC122.
...

A priori, il n'y a personne pour répondre à la question 🤔
