Which tool is used to capture and inspect network packets during a pentest?

• A. Nmap
• B. Metasploit
• C. Tcpdump
• D. Wireshark

Answer: (D)

Capturing and inspecting network traffic is about listening to the data moving over a network and parsing it to understand what’s being communicated. The best tool for this in a pentest context is Wireshark because it not only captures packets in real time, but also provides deep, human-readable analysis of all sorts of protocols. It decodes protocol fields, shows you headers and payloads, lets you reconstruct sessions, and you can filter precisely what you want to inspect. This makes it possible to spot sensitive data, misconfigurations, or unusual traffic patterns quickly, and you can save and later review captures. Nmap focuses on discovering hosts and services, not on analyzing the contents of individual packets. Metasploit is an exploitation framework, not a packet analyzer. Tcpdump can capture packets, but it’s command-line oriented and offers less in-depth, user-friendly inspection of protocol details compared to Wireshark’s rich dissectors and visualization.
