Which of the following is a tool that assists ethical hackers according to the text?

In the context of tools that assist ethical hackers, it's essential to recognize the usefulness of various tools in penetration testing and security assessments. While BurpGPT is listed in the options, it is important to note that the correct tool typically associated with ethical hacking is SQLMap, Nmap, or Wireshark.

SQLMap is an automated tool designed specifically for detecting and exploiting SQL injection vulnerabilities. It allows ethical hackers to target databases and perform attacks in a controlled manner to understand potential risks.

Nmap is widely used for network discovery and security auditing. It assists in mapping out networks and identifying available hosts and services, vital for a comprehensive penetration test.

Wireshark is an open-source packet analyzer that allows users to capture and inspect data packets in real-time. It is invaluable for network troubleshooting, analysis, and security assessments.

While BurpGPT may have advanced capabilities in web application security testing as a tool, it does not hold a prominent position in the traditional toolset like the other three mentioned. Thus, focusing on tools like SQLMap, Nmap, and Wireshark offers a better understanding of the methodologies and protocols that ethical hackers utilize in their work.
