Adam's organization has deployed RFID badges as part of their access control system. Adam is required to enter a 6-digit PIN when he uses his RFID badge and dislikes the additional step. What type of attack is the PIN intended to stop?

Radio frequency identification (RFID) badges can be cloned, but adding an additional factor like a PIN means the badge alone is not sufficient to gain access. Piggybacking involves following an authorized user through a security door or gate. On-path attacks inject an attacker into the middle of a transaction or network connection, allowing them to view and potentially modify traffic. Concurrent session usage or access is an indicator of compromise (IoC) that focuses on multiple systems or users using the same credentials.
