Hack Computers Inside 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 Nmap.



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.



You now need to create a null session to the target computer.



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.



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.

Create a text file called user.txt and the content will be the username of the Admin account.



Prepare yourself a good wordlist.



Now put both of them in the same directory with the NetBios Auditing Tool.



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.



Press on enter and the tool will run through the passlist.



In this case,I have get the password.

In order to proof that I can get access to the target computer using this password.



After you press enter,it will prompt you for the username and password.



Therefore,just input them inside the prompt and continue.



Target C drive will be on your screen.



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.

The download link of the tools will be:
Download Tools.rar

How to Trace an IP Address

Whenever you get online,your computer is assigned an IP address. If you connect through the router, all of the computers on that network will share a similar Internet Protocol address; though each computer on the network will have a unique Internet address. An IP address is the Internet Protocol (IP) address given to every computer connected to the Internet. An IP address is needed to send information, much like a street address or P.O. box is needed to receive regular mail. Tracing an IP address is actually pretty straightforward, and even though it's not always possible to track down a specific individual, you can get enough information to take action and file a complaint.
For example, if there was some guy claiming to be Chuck Norris, and tried to get personal information from your Gmail account, you could view his IP address, and then track him. Here's how:

STEP:

Click on Start>Accessories>Command Prompt.

Type PING [URL] or TRACERT [URL] - example: PING http://www.facebook.com/.

The IP address should appear beside the website name. The format of an IP address is numeric, written as four numbers separated by periods. The format of an IP address is numeric, written as four numbers separated by periods. It looks like 71.238.34.104 or similar.
<br

To find the IP of an e-mail sent to you, investigate the message's "headers." The steps to finding message headers depend on your email client.

Gmail for example:

• Log in to Gmail.
  
  
  
• Open the message you'd like to view headers for.
  
  
• Click the down arrow next to Reply, at the top of the message pane.
  
  
• Select Show Original.
  
  

Use the methods described above to obtain the IP number you wish to check.

Go to a website that will allow you to look up IP address information. Google "IP Lookup" or "IP Geolcation" for a large list of sites that will freely offer this service.

3

Understand what you can and cannot learn from the IP address:

• Which internet service provider (ISP) the user is using. In some cases this may be the user's company (e.g. Ford.com). In other cases it may be just one of the large ISPs such as ATT or Comcast.
• The approximate physical location of the user (e.g. Palo Alto, California.)
• Recognize that usually you will not learn the actual name of the person doing at that IP address (e.g. Joe Smith). ISPs will typically only release such information under a court order.

How To Get Data Off A Dead Hard Drive

 our computer and *BAM* that’s it. Bluescreen of death (BSOD). The hard drive has failed. But the baby shower pictures are on there! But my doctoral thesis is on there! But my fan fiction of Harry Potter Meets Captain Kirk is on there! But you’ve been making regular backups, right?
Fear not. You may be able to learn how to get data off a dead hard drive, all by yourself. Now a word of warning, if the hard drive has already physically failed and the disks in it won’t spin, then there isn’t much you can do but contact a data recovery specialist. I suppose you could order an identical hard drive via eBay and carefully take the platters out and put them into the new hard drive. However, if you are that technically inclined, this article is waybeneath you!
If you get a BSOD  then something may have happened to make your hard drive not boot, or start the operating system. This could be because of a faulty hard drive driver (the software that tells the computer how to use the hard drive) or it could be because of a loose connection. If you feel adventurous, you could check to make sure the connection is good inside the computer.

With some luck, that won’t be the case. If your computer continues on to give you some start up options in white text on a black screen, try choosing Last Known Good Configuration. That will start the computer into a backed-up version of Windows when life was good. It may be missing some recently added files and settings, but at least you’ll get the majority of your work back. At this point, it would be a good idea to perform a ScanDisk or CheckDisk task.

Your computer doesn’t take you to the start-up options page? Hmmm. Well, what you can do is try booting your computer from the Windows disk that came with your computer. Hopefully you have that still.
You may need to go into your BIOS settings and change the start-up disk setting to CD-ROM Drive.
Once your computer boots into the Windows disk,you’ll have some options. One of them will be the Recovery Console. Choose that by pressing the R key.

Chances are you only have one installation of Windows on your computer, so that’s the installation you’ll choose to work with.
When asked for your Administrator’s password, enter it and continue. If you didn’t set up an Administrator’s password, just hit enter to continue.
Now, you’ll be presented with a black screen with white text. At the prompt, type chkdsk /r. What this does is run the Check Disk utility on the hard drive and repairs any problems it might find. If this does the trick, your computer will reboot and work fine. Note, however, that now would be a VERY good time to make a back up of your hard drive and look into buying a new one. If this happens again, you’ll be very lucky to recover it once more.
If that doesn’t work, boot into the Recovery console again. There are two other commands you may want to try: Fixboot,which rewrites the startup sector on your hard drive, andFixmbr, which repairs the Master Boot Record.
Those are pretty advanced commands to use, so you may not want to run them. Run at your own risk, is all I can say.
There is also a device you can buy, which is pretty inexpensive, that allows you take your hard drive, connect it to this device, and then plug it into the USB port of another computer.This does require you to remove your hard drive from its current computer.

What happens is that the computer you plugged it into, treats it as a slave drive. That means that it doesn’t need to access the operating system, so you should be able to transfer over your files from the failing hard drive. The defunct hard drive shows up as an external USB drive in Window’s Explorer so you can simply drag and drop from it.
I have used one of these many times. What I have found is that as long as the platters spin, I’m able to recover the data.
Do you know of any other simple ways how to get data off a dead hard drive? Know of any good freeware? Has this article helped you? Help your Internet friends out and let us know about it in the comments.
