Repository Structure

ctf/
  tryhackme/
    pickle_rick/
      nmap/
        ...

• ctf/: Contains CTF challenge writeups and resources.
• tryhackme/: Subdirectory for TryHackMe rooms and walkthroughs.
• pickle_rick/: Example room with enumeration and exploitation artifacts.
• nmap/: Network scan outputs and enumeration results.

CTF Challenges

This repository includes detailed writeups and artifacts for various CTF challenges. Each challenge directory may contain:

• Reconnaissance and enumeration results (e.g., Nmap, Gobuster, Nikto outputs)
• Exploitation scripts and payloads
• Post-exploitation notes
• Flag locations and extraction methods

Penetration Testing Methodologies

The repository follows standard penetration testing phases:

1. Reconnaissance: Passive and active information gathering (WHOIS, DNS, OSINT).
2. Scanning & Enumeration: Network mapping (Nmap), service enumeration, vulnerability scanning.
3. Exploitation: Gaining access using exploits, custom payloads, or misconfigurations.
4. Post-Exploitation: Privilege escalation, persistence, data exfiltration.
5. Reporting: Documentation of findings, vulnerabilities, and remediation steps.

Tools & Techniques

• Nmap: Network discovery and vulnerability scanning.
• Gobuster/Dirbuster: Directory and file brute-forcing.
• Hydra/Medusa: Brute-force attacks on authentication services.
• Metasploit: Exploit development and execution.
• Burp Suite: Web application security testing.
• Custom Scripts: Python, Bash, and PowerShell scripts for automation.

Sample Nmap Command

nmap -sC -sV -oA nmap/initial <target-ip>
