HOW TO H!CK COMPUTER ON A LAN NETWORK


Today,I will write about hacking computer inside
the LAN network.
This technique will be taking advantage of Port
139.
Most of the time, Port 139 will be opened.
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.
I will scan it using ZeNmap.
Image
I get the result and it shows Port 139 is opened
up for me.
Now you will need both of these tools:
** USER2SID & SID2USER
** NetBios Auditing Tool
You can get both of them on the Internet.
After you get both of them,put them in the C:\
directory.
Image
You now need to create a null session to the
target computer.
Image
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.
Image
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.
Image
Now you will see that you get the username of
the Administrator account.
In this case,the Administrator account is
Administrator.
Create a text file called user.txt and the
content will be the username of the Admin
account.
Image
Prepare yourself a good wordlist.
Image
Now put both of them in the same directory
with the NetBios Auditing Tool.
Image
Now we are going to crack the Admin account
for the password in order to access to the
target computer.
Browse to the NetBios Auditing Tool directory.
Image
Press on enter and the tool will run through the
passlist.
Image
In this case,I have get the password.
In order to proof that I can get access to the
target computer using this password.
Image
After you press enter,it will prompt you for the
username and password.
Image
Therefore,just input them inside the prompt and
continue.
Image
Target C drive will be on your screen.
Image
In order to prevent from this attack,close down
port that you do not want to use such as Port
135,Port 136,Port 137,Port 138 and Port 139.
