Ziel: Duplizieren von Fitnessstudioarmbändern (Mifare Classic 1K)
Inhaltsverzeichnis
Erste Ansätze
Um die Armbänder zu duplizieren benötigt man zuerst einmal Informationen über den Chip.
NFC Tools Android App
https://play.google.com/store/apps/details?id=com.wakdev.wdnfc&hl=de
Diese App zeigt folgenden erkannten Chiptyp an:
-> Typ: ISO 14443-3A
-> MifareClassic
Nachdem wir wissen, dass es MIFARE Chips sind können wir ja auch mal die offizielle App verwenden:

Fazit: Die mitgelieferte Software und mfcuk wollten beide nicht so wie ich.
Mit miLazyCracker hat es letztendlich geklappt.
Die Daten liegen verschlüsselt vor und deswegen muss erst ein passender Key zur Entschlüsselung gefunden werden.
Wenn dies geschehen ist kann man die Originaldaten als Dump speichern.
