4. Password Cracking Tools:

Password cracking tools are used by ethical hackers to test the strength of passwords and assess the security of user credentials. By simulating password attacks, ethical hackers can identify weak passwords and advise organizations on implementing stronger authentication measures. Two common password-cracking tools are:

a. John the Ripper: John the Ripper is a fast and versatile password-cracking tool. It uses various techniques, such as dictionary attacks and brute force attacks, to crack password hashes and reveal weak credentials.

b. Hashcat: Hashcat is a powerful password recovery tool that supports various hashing algorithms and attack modes, making it efficient in cracking passwords for both online and offline attacks.

5. Web Application Scanners:

Web application scanners are indispensable tools for ethical hackers to assess the security of web applications. They identify vulnerabilities like SQL injection, cross-site scripting (XSS), and security misconfigurations, enabling organizations to secure their web assets effectively. Two widely used web application scanners are:

a. Burp Suite: Burp Suite is a comprehensive web vulnerability scanner and security testing platform. Ethical hackers use it to identify and validate web application vulnerabilities, along with its suite of other security testing tools.

b. OWASP ZAP (Zed Attack Proxy): OWASP ZAP is an open-source web application security scanner. It provides automated scanning and helps ethical hackers generate detailed reports for remediation.

6. Wireless Network Tools:

Wireless network tools play a crucial role in assessing the security of Wi-Fi networks. By identifying vulnerabilities in wireless protocols and configurations, ethical hackers aid organizations in securing their wireless infrastructure. Two essential wireless network tools are:

a. Aircrack-ng: Aircrack-ng is a popular suite of tools used for auditing wireless networks. It includes utilities for packet capturing, password cracking, and analyzing WEP and WPA/WPA2-PSK security.

b. Kismet: Kismet is a wireless network detector, sniffer, and intrusion detection system. It helps detect and analyze wireless networks, including hidden SSIDs and potential rogue access points.

7. Forensic Tools:

Forensic tools are vital for ethical hackers to investigate and analyze digital evidence in the event of a security incident. These tools enable them to understand the scope and impact of a breach and support organizations in responding appropriately. Two significant forensic tools are:

a. The Sleuth Kit (TSK): The Sleuth Kit is an open-source forensic toolkit that assists in digital investigation and analysis of file systems. It includes tools for file system analysis, data carving, and timeline generation.

b. Autopsy: Autopsy is a graphical user interface for The Sleuth Kit, making it more user-friendly for digital forensics investigations. It helps ethical hackers navigate through the investigation process efficiently.

8. Social Engineering Tools:

Social engineering is a technique that exploits human psychology to manipulate individuals into divulging sensitive information or performing certain actions. Ethical hackers use social engineering toolkits to simulate social engineering attacks and assess an organization’s susceptibility to such tactics. These tools assist in raising awareness about the risks of human vulnerabilities. One well-known social engineering toolkit is:

• Social-Engineer Toolkit (SET): The Social-Engineer Toolkit is a comprehensive and open-source tool that helps ethical hackers conduct various social engineering attacks, such as phishing, spear-phishing, and credential harvesting. It enables testers to understand the human element in cybersecurity and educate users to recognize and avoid social engineering threats.

9. Reverse Engineering Tools:

Reverse engineering involves analyzing and understanding the inner workings of software, firmware, or hardware to uncover vulnerabilities or extract valuable information. Ethical hackers leverage reverse engineering toolkits to inspect binary code, identify security flaws, and enhance overall system security. A prominent reverse engineering toolkit is:

• Ghidra: Developed by the National Security Agency (NSA), Ghidra is a powerful open-source reverse engineering tool that assists ethical hackers in decompiling and analyzing software binaries. It aids in identifying potential vulnerabilities and understanding malware behavior.

10. Exploit Development Frameworks:
