This video shows how to escalate privileges in the Lumen Industries AD lab by using BloodHound to find high-value targets and NetExec to retrieve LAPS credentials, achieving full RDP and SMB access to the internet server 2:03.
Key Takeaways:
• BloodHound reveals the compromised "internet service" user has Force Change Password rights over several domain users 4:00
• Mark S and Peter K are identified as high-value targets due to membership in the LAPS Admins group 6:50
• Using net rpc password, the presenter changes Mark S's password and authenticates as that user 10:00
• NetExec with --laps retrieves the internet server's local admin password, which LAPS rotates automatically 13:50
• The presenter gains RDP access via Remmina and captures the first flag on Mark S's desktop 17:50
The video closes by challenging viewers to independently perform post-exploitation and find a path to the domain controller, stressing that getting stuck is essential to learning 21:18.
