This technique will be taking advantage of Port 139.Most of the time,Port 139 will be opened.But if unfortunately your victim's Port 139 is filtered or closed then you can't hack him by this method .So guys follow these steps carefully and at the end you will be able to hack Lan computers.
NOTE : All the tools used in this tutorial have already been sent to all the Email subscribers to their emails,but if someone didn't got it then post your email in the
comments and if we find that email in subscription list we will send you
all the tools.
Steps to Follow
- First of all,I will do a port scanning at the target computer which is 192.168.40.128.This computer is inside my LAN network.
- Scan it using Nmap, this is actually for checking either its port is opened or closed.
- I get the result and it shows Port 139 is opened up for me.
- Now we will need both of these tools:
- USER2SID & SID2USER
- NetBios Auditing Tool
- I have already sent these tools to all the Email Subscribers.
- After you get both of them,put them in the C: directory.
- Now you need to create a null session to the target computer.For this open cmd prompt and write this below command as it is as shown in image below :
- Now open the Command Prompt and browse to the USER2SID & SID2USER folder.There will be 2 tools inside it,one will be USER2SID and another one will be SID2USER.
- We will first using USER2SID to get the ID.Just follow all the codes same as shown in below image ,just replace the IP Address of victim
- We will test against the Guest account because Guest account is a built in account.
- After we get the ID,we need to do some modification on the ID.
- We take the ID we get from the guest account and modified it become "5 21 861567501 1383384898 839522115 500".
- Please leave out the S-1-,leave out all the - too.
- Now you will see that you get the username of the Administrator account.
- In this case,the Administrator account is Administrator.
