The exhibit reveals duplicate IP addresses detected for 10.1.140.6, associated with two different MAC addresses:
88:56:56:ab:c6:89
88:13:30:a3:02:00
Key observations:
Duplicate IP Address Detection:
The message " Duplicate IP address detected for 10.1.140.6 " clearly indicates two devices claiming the same IP address.
This typically occurs when one device spoofs the MAC address of another device to intercept or disrupt traffic.
MAC Spoofing Context:
MAC spoofing is a tactic used to impersonate another device ' s hardware address to gain unauthorized access to a network.
By spoofing a legitimate IP-MAC pairing, an attacker can bypass security mechanisms or cause denial-of-service conditions.
Why the Other Options are Incorrect:
Option B (Mirroring Misconfigured): While mirroring misconfiguration can duplicate traffic, it does not lead to a " duplicate IP detected " alert.
Option C (Misconfigured DHCP): Misconfigurations usually result in DHCP conflicts, but they do not typically involve two different MAC addresses for the same IP.
Option D (ARP Poisoning/MITM): ARP poisoning involves falsified ARP tables, but it does not directly trigger duplicate IP address detection. Instead, ARP packets flood the network.
Conclusion:
The evidence strongly suggests MAC spoofing, as two different MAC addresses are claiming the same IP address (10.1.140.6). This behavior is typical of attempts to gain unauthorized access or disrupt network operations.
