Sicherheitsforscher von Quarkslab haben in RFID-Schl\u00fcsselkarten des Herstellers Fudan Microelectronics eine Backdoor entdeckt. Diese Schwachstelle erm\u00f6glicht das einfache Klonen von Schl\u00fcsselkarten, die in vielen Hotels und B\u00fcros weltweit verwendet werden. Die betroffenen Karten sind mit Mifare-Classic-Karten von NXP Semiconductors kompatibel, die bereits in der Vergangenheit anf\u00e4llig f\u00fcr Angriffe waren.<\/p>\n

Die Forscher fanden heraus, dass der auf den Karten verwendete geheime Schl\u00fcssel identisch ist, wodurch alle Karten schnell kompromittiert werden k\u00f6nnen. \u00c4ltere Modelle von NXP und Infineon zeigen \u00e4hnliche Schwachstellen. Ein Umstieg auf sicherere Systeme wird dringend empfohlen.<\/p>\n
