How to Find the IP Address of a Remote Computer

 

Most of you may be curious to know how to find the IP address of your friend’s computer or to find the IP address of the person with whom you are chatting in Yahoo messenger or Gtalk. In this post I’ll show you how to find the IP address of a remote computer in simple steps.

I have created a PHP script to make it easier for you to find the IP address of the remote computer of your choice. Here is a step-by-step process to find out the IP address.

1. Download the IP Finder script (IP_Finder.ZIP) that I have created.

2. Open a new account in X10Hosting (or any free host that supports PHP).

3. Extract the IP_Finder.ZIP file and upload the two files ip.php and ip_log.txt into the root folder of your hosting account using the File Manager.

4. You can rename the ip.php to any name of your choice.

5. Set the permission to 777 on ip_log.txt.

Now you are all set to find the IP address of your friend or any remote computer of your choice. All you have to do is send the link of ip.php to your friend or the person with whom you’re chatting. Once the person click’s on the link, his/her IP address is recorded in the file ip_log.txt.

For your better understanding let’s take up the following example.

Suppose you open a new account in X10hosting.com with the subdomain as abc, then your IP Finder link would be

http://abc.x10hosting.com/ip.php

You have to send the above link to you friend via email or while chatting and ask him to visit that link. Once your friend clicks on the link, his IP address will be recorded along with the Date and Time in the ip_log.txt file. After recording the IP address, the script will redirect the person to google.com so as to avoid any suspicion.

To find the recorded IP address check the logs using the following link.

http://abc.x10hosting.com/ip_log.php

The sample log will be in the following format

79.92.144.237 Thursday 07th of May 2009 05:31:27 PM
59.45.144.237 Thursday 07th of May 2009 05:31:28 PM
123.92.144.237 Thursday 07th of May 2009 05:31:31 PM

NOTE: You have to replace abc with your subdomain name. 

I hope this helps. Express your opinion and suggestions through comments.

 

How To Hack Orkut ???

 

Google uses a 4 Level Orkut login which makes it difficult to hack Orkut using brute force attack. Hence it’s almost impossible to use the brute force approach to hack Orkut account. Before we discuss how to hack Orkut lets take a look into the 4 level secure login feature of Orkut account.

First Level – Security-SSL or 128 bit secured connection

Second Level – Orkut account checks for cookie in the sytem of user

Third Level – Orkut provides a redirection to the entered User information

Fourth Level – Orkut doesn’t use conventional php/aspx/asp coding. So it is impossible to hack Orkut using input validation attack!!!

It is not an easy task to hack Orkut by breaking this security! However still some people manages to get access to other’s Orkut accounts. The question concerned is How they do it? Many of them just use simple tricks that fool users and then they themself leak out their password. Here are some points you need to take care of, to protect your Orkut account being hacked.



Ways to Hack Orkut Account

 

1. Using Keyloggers is one of the Easiest Way to Hack Orkut password. Keylogger programs can spy on what the user types from the keyboard. If you think that you can just uninstall such programs, you are wrong as they are completely hidden.

A keylogger, sometimes called a keystroke logger, key logger, or system monitor, is a hardware device or small program that monitors each keystroke a user types on a specific computer’s keyboard. Keylogger is the easiest way to hack an Orkut account.

A keylogger program is widely available on the internet. Some of the best ones are listed below

SniperSpy

Win-Spy

A detailed information on Keylogger Hack can be found in my post Hacking an Email Account.

2. Phishing Attack is the most popular way of hacking/stealing other’s password. This attact works by using fake login pages to fool innocent Orkut users to enter their Orkut username and password in these fake login pages instead of the real ones. When the users land on these page they enter their Orkut username and password thinking it to be the real page but actually it is other way round. It submits all the entered details to the creator of the fake login page. In this way it’s obvious for many people to lose their Orkut account password.

3. Orkut New Features: Some sites on internet may claim to offer many additional features for Orkut users. Also these sites will offer a login page from their own website and force users to login to their Orkut account from this page itself inorder to gain access to the additional features. In fact these sites are acam and they take away your password when you enter your Orkut username and password on their pages. This is similar to that of phishing attack.

4. Community Links: Many times you are provided with a link to a community in a scrap. Read the link carefully, It may be something like http://www.okrut.com/Community.aspx?cmm=22910233 OKRUT not ORKUT. This is definitely a trap created by the hacker to hack your Orkut password. Clicking on this link will take you to a fake login page and there you loose up your password.

5. Java script: You must have seen the circulating scraps that asks you to paste this code in your address bar and see what happens! Well sometimes they also leak out your information. Check the code and if you are unsure of what to do, then I recommend not to use it. So be careful, javascripts can even be used to hack Orkut!

6. Primary mail address: If by some means a hacker came to know the password of your Yahoo mail or Gmail, which users normally keeps as their primary mail address in their Orkut account, then hacker can hack Orkut account by simply using USER ID and clicking on ‘forget password’. This way Google will send link to the already hacked primary email ID to change the password of the Orkut account. Hence the email hacker will change your Orkut account’s password. Hence your, Orkut account is hacked too.

So a better thing would be to keep a very unknown or useless email ID of yours as primary email id so that if the hacker clicks on ‘Forgot password’ the password changing link goes to an unknown email id i.e. not known to the hacker. Hence your Orkut account saved.

So, I hope that this post not only teaches you to hack Orkut account but also to hack protect your Orkut account.

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 theWindowsSystem32 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 and 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.

 NOTE: You can also change the ICON of the virus to make it look like a legitimate program. This method is described in the post: How to Change the ICON of an EXE file ?

Please pass your comments and tell me your opinion. I am waiting just for your comments…

 

A Virus Program to Disable USB Ports

In this post I will show how to create a simple virus that disables/blocks the USB ports on the computer (PC). As usual I use 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 the you’ll will not be able to use your pen drive or any other USB peripheral 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.

1. Download the USB_Block.rar file on to your computer.

2. It contains the following 4 files.

• block_usb.c (source code)
• unblock_usb.c (source code)

3. 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).

4. 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 the unblock_usb.exe  (you need to compile unblock_usb.c) file. Now insert the pen drive and it should get detected.

5. 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).

I hope you like this post. Please pass your comments.
