RFID cards which a guest can get access to the allocated hotel room. Keeping an eye on the RFID technology and with an objective of exploiting it, John, a penetration tester, exploited a vulnerability in the hotel's RFID system and gained unauthorized access. John created a duplicate RFID card and then he identified the master key card code in several tries using an RFID card reading and writing tool. Then, he created its clone using a new RFID card. He used the card to roam in any hotel room in the building, identify the RFID attack John has performed on the target hotel?
