What technique is used by an attacker in MAC spoofing?

• A. Phishing for user’s credentials
• B. Sniffing the network for legitimate MAC addresses
• C. Brute forcing password hashes
• D. Accessing the network via unsecured Wi-Fi

Answer: (B)

In the context of MAC spoofing, the technique that involves sniffing the network for legitimate MAC addresses is particularly crucial. When an attacker performs MAC spoofing, they aim to impersonate another device by using its MAC address. To do this effectively, the attacker first needs to identify a legitimate MAC address that is currently in use on the network. This is typically achieved through network sniffing, where the attacker uses tools to capture the traffic on the network and extract the MAC addresses of devices that are communicating. By knowing which MAC addresses are valid on the network, the attacker can choose one to spoof, thereby gaining unauthorized access or impersonating a device that is allowed on that network. The other options do not relate directly to the specific technique of MAC spoofing. Phishing is more about stealing user credentials, while brute forcing relates to cracking passwords. Accessing unsecured Wi-Fi does not necessarily involve MAC addresses but rather potential vulnerabilities in the network itself. Thus, sniffing for MAC addresses is the fundamental action that enables the attacker to carry out the spoofing successfully.
