The exhibit shows multiple ARP reply packets with the same IP addresses (192.168.51.105 and 192.168.51.201) being mapped to different MAC addresses, which triggers the message: "duplicate use of [IP] detected". This is a strong indicator of an ARP spoofing (or poisoning) attack.

ARP spoofing occurs when a malicious actor sends falsified ARP messages to associate their MAC address with the IP address of another host. This misleads other devices on the network and allows interception or redirection of traffic.

The Cisco CyberOps Associate guide specifically recommends configuring port security on switches as a method to mitigate ARP spoofing, by limiting the number of MAC addresses allowed per port or statically assigning legitimate MAC addresses to switch ports.

The XML structure shows that:

The file name starts with: "Final Report"

The file extension equals: "doc.exe"

Together, this forms "Final Report.doc.exe" — a known double-extension technique used to disguise executables as benign documents. This is a red flag in email forensics, commonly linked to malware distribution, and explicitly covered in the Cisco CyberOps study material as a typical evasion method for malicious attachments.

The -h option in the objdump command displays section headers of an object file. According to general usage and command-line documentation, and also explained in digital forensics tools discussions in the CyberOps course, the header information includes details about the name, size, VMA, LMA, file offset, and alignment of each section in the object file. This helps analysts understand how data is stored and organized within compiled files during forensic examinations.

The goal of an incident response plan (IRP) is to provide structured procedures for responding to cybersecurity incidents in a way that limits damage, contains the threat, and ensures business continuity. As outlined in the NIST SP 800-61 and Cisco CyberOps Associate study guide, containment and minimizing the impact of incidents is the primary goal of an IRP.
