INFORMATION TECHNOLOGY

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

For this hack you will require the Ubuntu Live CD.

Steps involved :

1. Insert Ubuntu Live CD and boot from it.
2. Open terminal and install chntpw in Ubuntu. To do so use the following commands.

   sudo apt-get install chntpw

3. Now mount your Windows volume. In my case it was dev/sda1. Replace it with yours.

   sudo mkdir /media/WINDOWS
   sudo mount /dev/sda1 /media/WINDOWS

4. Now navigate to the Windows configuration folder.

   cd /media/WINDOWS/WINDOWS/system32/config/

5. To reset the administrator password enter

   sudo chntpw SAM

6. After completing this command you will see 5 different choices. Select the 1st one and press Enter and its done. 
7. Now restart your system, it will not ask any password.  

Almost all Newspaper and Journal started publishing a daily Sudoku puzzle in their comic or strip pages. And most of us, including me has nearly became addicted to solving these puzzles.

 I've zipped it at this link. For more about Mike, visit http://www.mikeoldroyd.com/.

If you have both programs, you can enter the puzzle in one form, then use Copy / Paste Special - Values to copy to the other program.

Microsoft Excel Work Book By Jerry:
Jerry from Erie, New York has created another workbook that is a Sudoku solver. This one is cool because it lets you see how to solve Sudoku iteratively. Enter the puzzle from the paper. Jerry's workbook shows you which squares can be solved right now. Click Solve to put those numbers in the grid. Then, new squares light up in yellow as being solvable.

Everyone wants web sites and web pages to load faster, there really isn’t anything more time wasting then waiting for a web site to load up, it really comes down to three main factors, your web browser, your internet connection and the server the website your trying to load. Obviously if you’ve got a crappy web browser, like IE6, then it’s going to take longer to load then say you were using Firefox, if you have a better internet connection, then you’ll be able to load websites better and if the website is hosted on a decent server, it’ll load faster.

Now I’ve always found Firefox is be pretty quick, but then I learnt you were able to modify some of the settings within Firefox to make it load websites even faster and in this how to, I’m going to show you exactly how you can boost the speed Firefox loads web pages at, plus explain what we’re changing and why, so instead of just following simple instructions, your learning what your changing and how it’s going to effect your website loading times.

If you really want too, you can use Addons for Firefox, which tell you how long it takes websites to load, one which I’m a fan of, is called Extended Statusbar, if you really want to work out how much you’ve increased your website loading times, you can use this sweet Firefox Addon to do so, so lets get started. But they won’t fix website loading time, but only show you info on this.

First off, we’re going to need to open up the config within Firefox, this is super easy to do, just open a new tab and type in the address bar, about:config – It’s that simple, you’ll then see some warning message because playing with the config settings can screw up your browser, so read carefully! Click “I’ll be careful, I promise” and lets get started!

At the top of the config, you’ll see a “Filter” bar, we’re going to be using this to find the fields we need to edit, which is going to save us a lot of time, the first thing we’re going to change, search for network.http.pipelining, it’ll be set to disabled by default, so change this to enabled. What pipelining is, in simple terms, it means you can send multiple requests to a server, before it has replied, not every server supports pipelining, but this is a decent way to speed up the load times on the websites which do support it, now find network.http.pipelining.maxrequests and set this to 8, this is the maximum number of pipelining requests Firefox will make, we’re also going to need to find network.http.proxy.pipelining and enable that too.


Now by default, if something was to pop up on your Firefox, it stops loading the webpage in the background, we are going to change this, so if a UI event does happen, the page will still load in the background, by default Firefox doesn’t have this one in the config, so right click (Anywhere white in the config) and click “New” and then “Boolean”, enter content.interrupt.parsing and set it to “True”, we’ve already made some changes to improve your speed, but there are still more we can make! If you’ve come this far, everything else is really simple to do.
For the rest of the tweaks, we’re going to need to add new data to our config, so instead of carrying on in a article format, I’ll leave it in a easier format for you to follow/read, there is a lot of copy/pasting involved as well, so this’ll make your life easier while following this article.

Create a new integer, name it content.max.tokenizing.time with a value of 2250000.
Create a new integer, name it content.switch.threshold with a value of 750000.
Create a new integer, name it content.notify.interval with a value of 750000.
Create a new integer, name it content.notify.backoffcount with a value of 5.
Create a new integer, name it nglayout.initialpaint.delay with a value of 0.
Create a new boolean, name it content.notify.ontimer and then set it to True.

Once you’ve done all of this, restart your Firefox (Close all Firefox windows, like you’ve just added a new add-on/updated your Firefox) and you’ll hopefully notice a huge increase in load times, I sure did!
