Which tool is known for its capability to capture traffic from various networks, including Bluetooth and Ethernet?

  1. bettercap

  2. Wireshark

  3. hping3

  4. Nbtstat

The correct answer is: Wireshark

Wireshark is recognized for its powerful packet analysis capabilities, allowing users to capture and display network traffic in real-time. It is versatile, supporting a wide range of protocols across different types of networks, including Ethernet, Wi-Fi, and even Bluetooth under certain configurations. The reason Wireshark stands out is due to its extensive protocol dissectors, which enable it to decode a multitude of protocols as they traverse the network. This functionality is critical for network administrators and security professionals to analyze communications and diagnose network issues, as well as for ethical hackers conducting assessments of system vulnerabilities. Other tools mentioned, while useful, have more specific functions. Bettercap is generally used for network attacks and penetration testing rather than a broad approach to traffic capturing. Hping3 is primarily a packet crafting tool and is utilized for creating custom TCP/IP packets for testing network security rather than passive traffic capture. Nbtstat, on the other hand, is specifically geared towards NetBIOS over TCP/IP, allowing users to troubleshoot and enjoy limited functionality in terms of network traffic analysis. Thus, Wireshark is the preferred tool for comprehensive traffic capture across diverse network types.
