To start out, let’s run a nmap scan to see what ports are open on the box.
Port 80 is open and running Microsoft IIS 7.5, a webserver. To do this, you will need to leverage methods like bruteforce, phishing, and exploits to gather passwords so you can identify the weak passwords, common passwords, and top base passwords used by an organization. From given you can observe port 3389 and port 445 are open and we know that 3389 is used for RDP and 445 is used for SMB.. cp /usr/share/windows-binaries/nc.exe smb. Since we are attempting to exploit a Windows target, we will want a Meterpreter payload type. Be thoughtful on the network you are taking this action on. Based on this assumption, Metasploit created a login for the credential and the SMB service. Now let’s find the Windows binary for Netcat and copy it to this directory we just made. Dismiss Join GitHub today. Looks like we’ve got everything in place!
