HYPERLINK "" Srikanth Ramesh53 CommentsThis post will show you how to?hack Windows administrator password?at times when you forget it or when you want to gain access to a computer for which you do not know the password.Most of us have experienced a situation where in we need to gain access to?a computer which is password protected or at times we may forget the administrator password without which it becomes impossible to log in to the computer. So, if you are somewhat in a same kind of situation, here is an excellent hack?using which you can reset?the password or make the password?empty (remove the password) so that you can gain?administrator access to the?computer.Hacking the Windows Admin Password:You can do this with a small tool called ? HYPERLINK "" \t "_blank" Offline NT Password & Registry Editor. This utility works offline, that means you need to shut down your computer and boot off your using a floppy disk, CD or USB device (such as pen drive). The tool has the following features:You do not need to know the old password to set a new one.This tool can detect and?unlock?locked?or?disabled?out user accounts!There is also a registry editor and other registry utilities that works under linux/unix, and can be used for other things than password editing.How it Works?Most Windows operating systems stores the login passwords and other encrypted passwords in a file calledsam?(Security Accounts Manager). This file can be usually found in?\windows\system32\config. This file is a part of Windows registry and remains inaccessible as long as the OS is active.?Hence, it is necessary that you boot off?your computer and access this?sam?file via the boot menu. This tool intelligently?gains access to this file and will reset/remove the password?associated with administrator or any other account.The download link?for both CD and?floppy drives?along with the complete instructions is given below:Offline NT Password & Reg Editor DownloadIt is recommended that you download the CD version of the tool since the floppy drive is outdated or doesn’t exist in today’s computer. After the download, you’ll get a bootable image which you need to burn it onto a blank CD. Now, boot your computer from this CD and follow the screen instructions to reset the password.Another Simple Way to Reset Non-Administrator Account Passwords:Here is another simple way through which you can reset the password of any non-administrator accounts. The only requirement for this is that you need to have administrator privileges. Here is a step-by-step instruction to accomplish this task:Open?the command prompt (Start -> Run -> type?cmd?-> Enter)Now type?net user?and hit EnterNow the system will show you a list of user accounts on the computer. Say for example, you need to reset the password of the account by name?John, then do as follows:Type?net user John *?and hit Enter. Now, the system will ask you to enter the new password for the account. That’s it. Now you’ve successfully reset the password for John without knowing his old password.So, in this way you can reset the password of any Windows account at times when you forget it so that you need not re-install your OS for any reason. I hope this helps.How to Repair Windows Registry the Easy WayHOW-TO GUIDES,?WINDOWS HACKS| Posted by? HYPERLINK "" Srikanth Ramesh22 CommentsThis article?explains how to inspect and?repair the registry errors?in your Windows PC so as to?improve?its overall?performance.

HYPERLINK "" Srikanth Ramesh78 CommentsThe?hosts file?is one of the interesting and useful feature of both Windows and Linux operating systems that provides many handy options in addressing network nodes. For instance, you can use the?hosts?file to block?annoying ads, pop-ups, banners, porn sites, or even redirect one website to another.In this post I will show you how to play around with the?hosts?file to accomplish some of the above mentioned jobs.What is a hosts File?The?hosts?file is just like any other computer file that is used by the operating system to map hostnames and domain names on to their corresponding IP addresses.In other words, when you type “” on your browser’s address bar, your computer will look for thehosts?file to see if it contains the?corresponding?IP address for the domain name you typed (). In case if no entry is present in the?hosts?file, the request is then passed on to the DNS (Domain Name System) server to obtain the IP address.hosts File vs. DNSWhen it comes to resolving the hostnames, the?hosts?file is given the first priority over the Domain Name System.?In most cases, the?hosts?file remains unconfigured on the operating system and hence the DNS is used by the computer to resolve the domain names to their?corresponding?IP addresses.However, if the?hosts?file is found to contain a valid entry for a given hostname or domain name, then this is picked up and used by the operating system.Where is the hosts File Located?Windows:?In case of the Windows operating system, the?hosts?file is located at:%systemroot%\system32\drivers\etc\hostsNOTE:?In most cases this should be:?C:\Windows\System32\drivers\etc\hostsUnix/Linux:?In case of Linux it is located at:/etc/hostsHow to Block a Website?To block a specific website, all you have to do is just add a new entry for that site in the?hosts?file. I would prefer to backup the original file and create a new one instead of modifying it. So, if something goes wrong, you can just delete it and restore the original one! Well, here is a step-by-step procedure on how to create a new?hostsfile on Windows:Go to “My Computer” and you should see the “Menu bar” on top. In case of?Vista?and?Win 7, just click “Alt” to unhide the “Menu bar”.Now in the menu bar, click on “Tools -> Folder Options”. In the “View” tab?uncheck?the option that says: “Hide extensions for known file types” and click on “OK”.Open a new text pad (New Text Document.txt) and rename it to:?hosts. You will get a pop-up message with a warning. Just click on “Yes”.Please note that the renamed file?hosts?should not have any extension?such as?hosts.txt.Open the?hosts?file using the notepad. Now let us assume that you want to block the sites?Facebook?andYoutube?on your computer. For this all you have to do is add the following lines to your?hosts?file:127.0.0.1???????127.0.0.1???????127.0.0.1???????127.0.0.1???????Each entry should be placed on an individual line. The IP address and the hostname should be separated by a space or a tab. In this way, you can block any given website by just pointing it to the IP address 127.0.0.1.Navigate to?%systemroot%\system32\drivers\etc. Here you should see the original?hosts?file, rename it to?hosts_bak. Just copy and paste the new?hosts?file that you have created. That’s it. You’ve now successfully blocked those websites from loading on your computer.If you are using Vista/Win 7 you may have to?take ownership?of the original?hosts?file before renaming it.How to Redirect a Website?Suppose you want to redirect??to?, all you have to do is just add the following lines to your?hosts?file:74.125.236.72???????74.125.236.72???????Here?74.125.236.72?is the IP address of . To find out the IP address of any given website, just go to command prompt and ping it. For example:?ping . You should get a ping response that displays the IP address as shown below:From now on, whenever you type “” on your browser, you will be redirected to “”.How does a hosts File work?Whenever you block a website using the?hosts?file, you point it to the IP address?127.0.0.1?which in fact is the IP address of your own computer. In other words, the IP 127.0.0.1 points to your own computer and doesn’t exist outside.So, whenever you type the URL of a website for which an entry is present in the?hosts?file, your computer will load the IP as 127.0.0.1 instead of the actual one and tries to establish a connection with this IP address (127.0.0.1) but fails. As a result the website doesn’t load at all.The redirection of the website works by pointing the domain name of one website to the IP address of another website (as configured by the?hosts?file) instead of its original IP address. So, whenever you type , it is pointed to ’s IP address and thus, the Google page loads up instead of the actual page from .How to Block the Annoying Ads?I have found a great solution to keep all the annoying ads, banners, pop-ups and other parasites at bay by using a pre-configured?hosts?called?MVPS?hosts?file. This?hosts?file contains a long list of entries to block all those annoying ads and pop-ups that usually load while you are surfing the Internet. You can also receive regular updates on this to stay up-to-date. You can download MVPS hosts file from the link below:Download MVPS hostsIf you are playing around with the?hosts?file and something goes wrong, just delete the?hosts?file itself and rename the original file from?hosts_bak?to?hosts. This should bring back everything to normal. I hope this post on?hosts file?will help you block unwanted websites on your computer. How to Create a Virus to Block WebsitesHOW-TO GUIDES,?PROGRAMMING| Posted by? HYPERLINK "" Srikanth Ramesh65 CommentsMost of us are familiar with the virus that used to block Orkut and Youtube websites. If you are curious about creating such a virus on your own, here is how it can be done.As usual I am using my favorite programming language?‘C’?to create this?website blocking virus. I will give a brief introduction about this virus before I jump into the technical jargon.This virus has been exclusively created in?‘C’. So, anyone with a basic knowledge of ‘C’ will be able to understand the working of this virus program. When this program is executed, it will block all those websites that are listed in the source code. In the following example, the sites that are listed in the source code are Google, Yahoo and Youtube. When you download the source code of this program, you have a choice to include your own list of sites that you want this virus to block.I have just removed the source code of this program from this post as it is lengthy and makes the post look messy. You can still download the source code of this virus program from the following link:Download Block_Site.rarHow Virus Program Works?The Windows operating system maintains a special file called HOSTS which can be used to block any given hostname or domain name (website) by adding new entries onto it. This program works by modifying the HOSTS file by adding new entries of those sites that are intended to be blocked. The HOSTS file is located at:%windir%\system32\drivers\etc?(Usually: C:\windows\system32\drivers\etc)So, when you execute this program, all it does is add the entries of the list of those sites (mentioned in the source code) to this HOSTS file. Once this is done, the site will be blocked from your computer. So, none of the browsers would be able to load those sites on your computer.For more information on HOSTS file, I recommend reading my other post on?How to use HOSTS file to block websites.Now, as far as the technical part of this program is concerned, people who have a working knowledge of ‘C’ should be easily able to understand the working of this virus program. However, for those who are new to ‘C’ programming, here is the algorithm of this program:Determine the Root drive. ie: Find the drive (C:, D:, E: or F:) on which the Windows is installed.Navigate to: %windir%\system32\drivers\etcOpen/Load the HOSTS file.Copy a list of those websites that are mentioned in the ARRAY to the END of the file.Save the file and Exit.How to Compile the Source Code?For a step-by-step compilation?guide, refer my post:?How to compile C Programs?Testing the Virus:To test, run the compiled module. It will block the sites that are listed in the source code.Once you run the file?block_Site.exe, restart your browser program. Then, type the URL of the blocked site and you’ll see the browser showing error “Page cannot displayed“.To remove the virus type the following command in the?Run.%windir%\system32\drivers\etcThere, open the file named “hosts” using the notepad. At the bottom of the opened file you’ll see something like this:127.0.0.1 Delete all such entries which contain the names of blocked sites.How to Make An Invisible Password Protected FolderHOW-TO GUIDES,?WINDOWS HACKS| Posted by?

Now, the folder becomes invisible once again.I hope that you’ve now understood how to create an invisible password protected folder in Windows. If you like this post, pass your comments! Cheers?A Virus Program to Disable USB PortsPROGRAMMING,?WINDOWS HACKS| Posted by? HYPERLINK "" Srikanth Ramesh43 CommentsIn this post, I will show how to create a simple virus that?disables the?USB portson the computer (PC). As usual, I am using my favorite C programming language to create this virus. Anyone with a basic knowledge of C language?should be able to understand the working of this virus program.Once this virus is executed it will?immediately?disable all the USB ports on the computer. As a result you’ll will not be able to use?your pen drive or any other USB peripheral devices on?the computer. The source code for this virus is available for download. You can test this virus on your own computer without any worries since I have also given a program to re-enable all the USB ports.Download the source code of the virus program on to your computer from the following link:Download the USB_Block.rarThe download contains the following 2 files:block_usb.c (source code)unblock_usb.c (source code)You need to compile them before you can run it. A step-by-step procedure to compile C programs is given in my post -?How to Compile C Programs.3. Upon compilation of block_usb.c you get?block_usb.exe?which is?a simple?virus that will block (disable) all the USB ports on the computer upon execution (double click).To test this virus, just run the?block_usb.exe?file and insert a USB pen drive (thumb drive). Now you can see that your pen drive will never get detected. To re-enable the USB ports just run theunblock_usb.exe? (you need to compile unblock_usb.c) file. Now insert the pen drive and it should get detected.You can also change the icon of this file to make it look like a legitimate program. For more details on this refer my post –?How to Change the ICON of an EXE file?(This step is also optional).How it Works?The idea behind the working of this virus is pretty straightforward. It works by gaining access to the Windows registry and modifying its settings to disable the USB device support on the computer.On the other hand, the other program will re-set the registry settings back to the normal so that the support for USB devices is re-enabled.

HYPERLINK "" Srikanth Ramesh81 CommentsMost of you may be curious to know about?how to?make a Trojan?or Virus on your own. Well, here is an answer to your curiosity. In this, post I’ll show you?how to?make a simple trojan?on your own using the C programming language.This trojan when executed will eat up the hard disk space on the root drive (The drive on which the Windows is installed, usually C: Drive) of the computer on which it is run. Also, this trojan works pretty quickly and is capable of eating up approximately 1 GB of hard disk space for every minute it is run.So, I’ll call this as Space Eater Trojan. Since this program is written using?a high level programming language, it is often undetected by antivirus programs. The source code for this program is available for download?at the end of this post.?Let’s see how this trojan works:Before I move on to explain the working of this program, you need to know?what exactly is a Trojan horseand how?it works. Unlike what many of us think, a trojan horse is not a virus.?In simple words, it is just a program that appears to do a?favorable?task but in reality performs undisclosed malicious functions that allow the attacker to gain unauthorized access to the host machine or cause a damage to the computer.Now let’s move on to the working of our Trojan:The trojan horse which I have created appears itself as an antivirus program that scans the computer for malware programs. However, in reality it does nothing other than eating up the hard disk space on the root drive by filling it up with a huge junk file. The rate at which it fills up the hard disk space it too high. As a result, the the root drive gets filled up completely with in minutes of running this program.Once the disk space is full, the trojan reports that the scan is complete. The victim will not be able to clean up the hard disk space using any of the cleanup program. This is because, the trojan intelligently creates a huge file in the?Windows\System32?folder with the?.dll?extension. Since the junk file has the?.dll?extension it is often ignored by the disk cleanup software. Hence there is now way to recover the hard disk space other than reformatting the drive.The algorithm of the Trojan is as follows:Search for the?root drive.Navigate to?%systemroot%\Windows\System32?on the root drive.Create the file named “spceshot.dll“.Start?dumping the junk data?onto the above file and keep increasing its size until the drive is full.Once the drive is full,?stop the process.You can?download?the Trojan source code?HERE. Please note that I have not included the executable for security reasons. You need to compile it to obtain the executable.How to compile the program?For step-by-step compilation?guide, refer my post?How to compile C Programs.How to test this trojan horse?To test the trojan, just run the?SpaceEater.exe?file on your computer.

HYPERLINK "" Srikanth Ramesh79 CommentsIn this post, I will show you how to create a?virus to restart the computer?at every startup. That is, upon infection, the computer will get restarted every time the system is booted. As a result, the computer will become inoperable as it reboots again as soon as the desktop is loaded.For this, the virus needs to be executed only once and from then on, it will carry out rest of the operation on its own. I have programmed this virus using the C language. If you are familiar with the?C language?then it is too easy to understand the logic behind the coding. The code is not posted here in this article, but you can download it from the link piling the source code into an executable module:Download the?Source Code Here.UnRar the file and you should see the source code: Sysres.CFor a step-by-step compilation?guide, refer my post:?How to compile C Programs?Testing and removing the virus from your PC:You can compile and test this virus on your own PC without any fear. To test, just double-click the?sysres.exefile and restart the system manually. From now on, every time the PC is booted and the desktop is loaded, your PC will restart automatically again and again.It will not do any harm apart from automatically restarting your system. After testing it, you can remove the virus by following the below mentioned steps:Reboot your computer in the?safe mode.Go to:%systemroot%\Windows\System(%systemroot%?can be C,D,E or F)You will find a file by name?sysres.exe, delete it.Type?regedit?in?run. You will go to the registry editor. Here navigate to:HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\RunThere, on the right site you will see an entry by name “sres“. Delete this entry. That’s it. You have now removed this virus successfully.Logic Behind the working of this virus program:If I do not explain the logic(Algorithm) behind the working of the virus program, I think this post would become an incomplete one. So I’ll explain the logic in a simplified manner without getting much into the technical aspects of the program. If you have further doubts, you can pass your comments.LOGIC:First the virus will find the Root partition (Partition on which Windows is installed).Next, it will determine whether or not the virus file (sysres.exe) is already copied into%systemroot%\Windows\System.If not it will just place a copy of itself into?%systemroot%\Windows\System?and makes a registry entry to put this virus file into the Windows startup.Or else if the virus is already found in the?%systemroot%\Windows\System?directory (folder), then it just gives a command to?restart?the computer.This process is repeated every time the PC is restarted.NOTE:?The system will not be restarted as soon as you double click the?Sysres.exe?file.The restarting process will occur from the next boot of the system.How to change the icon of the executable module (This step is optional):After you compile, the?sysres.exe?file that you get will have a?default icon. If you send this file to your friends they may not execute it since it has a default ICON. So it is possible to change the ICON of this?Sysres.exe?file into any other ICON that is more trusted and looks attractive.For example, you can change the icon into?Norton antivirus?ICON itself so that the people seeing this file believes that it is?Norton antivirus. Or you can change its ICON into the ICON of any popular or trusted programs so that people will definitely click on it.How to Use Google for HackingGOOGLE HACKS,?HOW-TO GUIDES| Posted by? HYPERLINK "" Srikanth Ramesh78 CommentsGoogle serves almost 80 percent?of all the search queries on the Internet, proving itself as the most popular search engine. However, Google makes it possible to reach not only the publicly available information resources, but also gives access to some of the most confidential information that should never have been revealed.In this post, you will find the information on how to use Google for exploiting security vulnerabilities that exists within many websites.?The following are some of the?ways to use Google for hacking:1. Using Google to Hack Security Cameras:There exists many security cameras that are used for monitoring places like parking lots, college campus, road traffic?etc. With Google, it is possible to hack these cameras so that you can view the images captured by them in real time. For this, all you have to do is just use the following search query in Google. Type in the Google search box exactly as given below and hit enter:inurl:”viewerframe?mode=motion”Click on any of the search results (Top 5 recommended) and you will gain access to the live camera which has full controls. You will see something as follows:As you can see in the above screenshot, you now have access to the?Live cameras?which work in real-time. You can also move the cameras in all the four directions, perform actions such as zoom in and zoom out. This camera has really a?less refresh rate. But there are other search queries through which you can gain access to other cameras which have faster refresh rates. In order to access them, just use the following search query:intitle:”Live View / – AXIS”Now, click on any of the search results to access a different set of live cameras. Thus, you have hacked Security Cameras using Google.2. Using Google to Hack Personal and Confidential Documents:Using Google, it is possible to gain access to an email repository containing CV of hundreds of people which were created when applying for their jobs. The documents containing their?Address, Phone, DOB, Education, Work experience etc. can be found just in seconds.intitle:”curriculum vitae” “phone * * *” “address *” “e-mail”You can gain access to a list of .xls files (excel documents) which contains contact details including email addresses of large group of people. To do so, type the following search query and hit enter:filetype:xls inurl:”email.xls”Also, it is possible to?gain access to the documents potentially containing information on bank accounts, financial summaries and credit card numbers using the following search query:intitle:index.of finances.xls3. Hacking Google to Gain Access to Free Stuffs:Ever wondered how to hack Google for free music or eBooks. Well, here is a way to do that. To download free music, just enter the following query on Google search box and hit enter.“?intitle:index.of?mp3?eminem“Now, you’ll gain access to the whole index of Eminem album where in you can download the songs of your choice. Instead of eminem you can substitute the name of your favorite album. To search for the eBooks all you have to do is replace “eminem” with your favorite book name. Also replace “mp3″ with “pdf” or “zip” or “rar”.I hope you enjoy using Google for hacking stuffs on the Internet. If you’ve liked this post, please pass your comments. Cheers! ................
