Hacking is the practice of modifying the features of a system, in order to accomplish a goal outside of the creator's original purpose. The person who is consistently engaging in hacking activities, and has accepted hacking as a lifestyle and philosophy of their choice, is called a hacker.

Computer hacking is the most popular form of hacking nowadays, especially in the field of computer security, but hacking exists in many other forms, such as phone hacking, brain hacking, etc. and it's not limited to either of them. Find out more here...

How to Compile C Programs


In my previous post especially in the Trojan Creation section, I have used C as the programming language for writing the programs. If you’re new to C programming and find it difficult to compile the C source codes then this post is for you.
Here is a step-by-step procedure to install Borland C++ compiler 5.5 on your PC and compile the C programs.

How to Install Borland C++ compiler?

Follow the below steps to install Borland C++ compiler 5.5 on your PC:
  1. Download Borland C++ compiler 5.5 (for Windows platform) from the following link:
  2. After you download, run the file C++5.51.exe. The default installation path would be:
    C:\Borland\BCC55

How to configure Borland C++ compiler?

Here is a step-by-step instruction on how to configure the compiler:
  1. After you install Borland C++ compier, create two new Text Documents.
  2. Open the first New Text Document.txt file and add the following two lines into it:
    -I”c:\Borland\Bcc55\include”
    -L”c:\Borland\Bcc55\lib”
    Save changes and close the file. Now rename the file from New Text Document.txt to bcc32.cfg.
  3. Open the second New Text Document (2).txt file and add the following line into it:
    -L”c:\Borland\Bcc55\lib”
    Save changes and close the file. Rename the file from New Text Document (2).txt to ilink32.cfg.
  4. Now copy the two files bcc32.cfg and ilink32.cfg, navigate to C:\Borland\BCC55\Bin and paste them.

How to Compile the C Source Code (.C files)?

Here is a detailed instruction on how to compile C source codes:
  1. You need to place the .C (example.c) file to be compiled in the following location:
  2. C:\Borland\BCC55\Bin
  3. Now go to the command prompt (Start->Run->type cmd->Enter)
  4. Make the following path as the present working directory (use the CD command):
  5. C:\Borland\BCC55\Bin
  6. To compile the file (example.c) use the following command:
  7. bcc32 example.c
  8. Now if there exists no error in the source code, you’ll get a compiled executable module (example.exe) in the same location (C:\Borland\BCC55\Bin).
  9. Now you have successfully compiled the source code into an executable file(.exe file).
    NOTE: The above tutorial assumes that you’ve installed the compiler onto the C: drive (by default).

How to Make a TROJAN HORSE


Most of you may be curious to know about how to make a Trojan or Virus on your own. Here is an answer for your curiosity. In this post I’ll show you how to make a simple Trojan on your own using C programming language. This Trojan when executed will eat up the hard disk space on the root drive (The drive on which 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 Trojan is written using a high level programming language it is often undetected by antivirus. The source code for this Trojan is available for download at the end of this post. Let’s see how this Trojan works…
Before I move to explain the features of this Trojan you need to know what exactly is a Trojan horse and how it works. As most of us think a Trojan or a Trojan horse is not a virus. In simple words a Trojan horse is a program that appears to perform a desirable function but in fact performs undisclosed malicious functions that allow unauthorized access to the host machine or create a damage to the computer.
Now lets move to the working of our Trojan
The Trojan horse which I have made appears itself as an antivirus program that scans the computer and removes the threats. But in reality it does nothing but occupy the hard disk space on the root drive by just 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 disk gets filled up to 100% with in minutes of running this Trojan. 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 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 extention it is often ignored by disk cleanup softwares. So for the victim, there is now way to recover the hard disk space unless reformatting his drive.
The algorithm of the Trojan is as follows
1. Search for the root drive
2. Navigate to WindowsSystem32 on the root drive
3. Create the file named “spceshot.dll
4. Start dumping the junk data onto the above file and keep increasing it’s size until the drive is full
5. Once the drive is full, stop the process.
You can download the Trojan source code HERE. Please note that I have not included the executabe for security reasons. You need to compile it to obtain the executable.
How to Compile, Test & Remove the Damage
Compilation:
For step-by-step compilation guide, refer my post How to compile C Programs.
Testing:
To test the Trojan,  just run the SpaceEater.exe file on your computer. It’ll generate a warning message at the beginning. Once you accept it, the Trojan runs and eats up hard disk space.
NOTE: To remove the warning message you’ve to edit the source code and then re-compile it.
How to remove the Damage and free up the space?
To remove the damage and free up the space, just type the following in the “run” dialog box.
%systemroot%\system32
Now search for the file “spceshot.dll“. Just delete it and you’re done. No need to re-format the hard disk.
Please pass your comments and tell me your opinion. I am just waiting for your comments…

Hacking Yahoo Messengar

                                      
  This tutorial will tell you how to hack yahoo messengar while you are engaged in chatting with some person. While you are chatting through yahoo messenger, Yahoo will hide the IP addresses of all the computers that are connected  through the yahoo messenger application to the chat room. So it is not possible to directly find out the IP of the person you want to hack. Then how to get  the IP address? Yes it is still possible to hack the IP address during the Yahoo messenger chat. The Procedure to Hack Yahoo messenger is discussed in detail below.            

While you are chatting via yahoo messenger the communication between you and the person you want to hack, takes place indirectly via Yahoo server and not directly. It is not possible to hack Yahoo messenger directly to get the IP address. So to hack his IP, you must establish a direct communication with him. So ,how to do this? It’s easy. Just start chatting with some one via Yahoo messenger. During the process of chatting send him a big file. Now the file transfer takes place directly between your computer and the victim’s computer(via yahoo messenger application). So now, you are ready to go. Here’s the step-by-step process to hack Yahoo messenger and get the IP address of the person .
  • Goto the COMMAND PROMPT (START>>>RUN>>>Type CMD).
  • Here Type “netstat -n” (without quotes).
NOTE: If you are new to “netstat” and other IP related commands refer this tutorial: Windows XP IP Utilities

  • The pic given below shows netstat results of my computer. I was not chatting when i took this pic and hence it looks modified.
  
  • Here local address is your own IP and the foreign address is the IP address of the recipient with whom you are connected via yahoo messenger (There may be multiple recipients and hence multiple foreign addresses).
  • Now send him the file.
  • Check the output by typing the command “netstat -n” (without quotes).
  • Assume the output is something like this.
  • TCP 127.0.0.10:5101 124.55.23.11:1246 ESTABLISHED
    Here 124.55.23.11 is the IP address of the person with whom you are chatting and 1246 is the port number where connection is established. That’s It! You have now hacked Yahoo messenger to get his IP address.
    Once you hack Yahoo messenger and get his IP address you can use any of the Remote Administration tools or perform NETBIOS HACKING.
    NOTE: Some times there are chances where in the file transfer gets encrypted (takes place via yahoo server itself). So in this case the above hack may fail to work.

PHISHING TUTORIAL:STEP BY STEP EXPLAINED





What is Phishing ?

In the field of computer security, phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication. Communications purporting to be from popular social web sites
, auction sites, online payment processors or IT Administrators are commonly used to lure the unsuspecting. Phishing is typically carried out by e-mail or instant messaging, and it often directs users to enter details at a fake website whose look and feel are almost identical to the legitimate one. Even when using server authentication, it may require tremendous skill to detect that the website is fake.



How To Do Phishing ?


STEP 1: Firstly U Must Signup For A Free Web Hosting Service Like:

  1.  freehostia.com
  2.  000webhost.com (recommended)
STEP 2: Now Goto your email account that you gave and confirm your account with confirmation link


STEP 3 : Now Login To Your freehostia Account And Go To "File Manager" In The Freehostia Control Panel.

                                                                                         OR

 Goto  http://members.000webhost.com/ and Log into your account and go to file manager in files

STEP 3:Now what you have to do is, go to your domain folder like "yourname.freehostia.com" and create a seperate folder in that directory.with the name of the site, for eg. Gmail , if you want to phish a gmail account!

For FB Phishing :-  
Step 4 : Now Download this FILE (http://www.mediafire.com/?klq1vak76bouzrw )

Step 5 : Now Click on the Public_html.(000webhost.com>files>file manager)

Step 6: Now click on the Upload button, choose the file under the Archives that you have downloaded, to be uploaded.

Step 7: Now any one who visits your site would be taken to the Fake Facebook Login Page. After they enter their Username and Password, they will be taken to another page that will show them error. So there is less chance that it will be detected.
 

 For Gmail Phishing:- 
STEP 4 :
Now click here to Download and extract the file "phishers created by jafar.rar" to your desktop. And then open your "gmail" folder. You'll find two files there viz. "jafar.php" & "index.htm" (each phisher folder contains same files)

STEP 5:
Now upload "jafar.php" & "index.htm" to the "gmail" folder you created inside "yourname.freehostia.com"


So when you're done with the uploading part, the link to your gmail phisher is "www.yourname.freehostia.com/gmail/index.htm".

STEP 6:
Congrats!! That is your gmail phisher!! Now all you have to do is copy the link to the phisher file i.e. "www.yourname.freehostia.com/gmail/index.htm"

And send it to the victim you want to hack! When he/she'll open that link, it'll be directed to your gmail phisher and when he/she logins that page
He/she'll be redirected to the original "gmail" website and you'll get the password in the "jafar.txt" file which will be created in the gmail folder. You created in your freehostia domain and the path to that file will be "www.yourname.freehostia.com/gmail/jafar.txt" !


IMPORTANT NOTE:
CHANGE YOUR FREEHOSTIA DIRECTORY PERMISSION TO 755 SO THAT NO ONE CAN VIEW YOUR PERSONAL FILES EXCEPT THE PHISHER!!

**HAPPY PHISHING**.
