Which technique involves impersonating another device by altering the MAC address to bypass access controls?

• A. War driving
• B. MAC spoofing
• C. Rogue access points
• D. Client mis-association

Answer: (B)

MAC spoofing is the act of changing a device’s MAC address to imitate another device. Many wireless networks rely on MAC addresses for access controls, so by altering their own MAC to match a trusted or whitelisted one, an attacker can bypass those controls and gain access as if they were the legitimate device. This technique is specifically about modifying the hardware address to spoof identity, which is different from war driving (scanning networks), rogue access points (deploying an unauthorized AP), or client mis-association (connecting to the wrong AP).
