What is your BEST assessment regarding ARP poisoning after examining the results in the following case?
As the cybersecurity specialist for your organization, you suspect a hacker is accessing your network via ARP poisoning. You used Wireshark to collect packets and then filtered the results to test your hypothesis.

Examining the captured packets in Wireshark and identifying duplicate response IP addresses is a strong indication of ARP poisoning. ARP poisoning occurs when a malicious actor sends out spoofed ARP replies, associating their MAC address with a legitimate IP address. This effectively tricks network devices into sending traffic to the attacker instead of the intended destination.
The presence of duplicate response IP addresses suggests that multiple systems on the network are receiving conflicting ARP replies, causing them to send traffic to the wrong destination. This is a hallmark of ARP poisoning attacks.
