You have gained hands-on experience and practical knowledge in ethical hacking and penetration testing. Key lessons include setting up a lab environment with tools like VirtualBox and Kali Linux, conducting comprehensive enumeration using tools such as Nmap, RustScan, and Gobuster, and exploiting vulnerabilities with Metasploit and Exploit-DB.
Additionally, you have learned essential skills like file transfer using a Python server, local enumeration with linPEAS, and privilege escalation through GTFOBins. These skills are crucial for identifying and mitigating security vulnerabilities effectively.
