In a recent audit of a secure facility, it was noted that the employee access system employs badges that are not programmed to confirm the identity of the badge reader before transmitting data. Which specific vulnerability are these badges most at risk of?
The badges in question are at risk of Radio-Frequency Identification (RFID) cloning. The lack of a mutual authentication process in the badge system permits an attacker to capture the badge's signal and create a duplicate without being verified by the reader. This can allow unauthorized individuals to gain access to secured areas. Mutual authentication requires a badge and its reader to verify each other before any data is exchanged. The other options do not specifically relate to this radio-frequency vulnerability: email compromise and social-engineering tactics involve different threat vectors, while encryption breaking addresses cryptographic weaknesses rather than the duplication of RFID credentials.
