Take you ever wished you could create your own virus, either for your own learning or every bit a prank? Virus creation takes fourth dimension and knowledge, simply anyone can practice it if they put their mind to it. Creating a virus tin can teach you a lot about how a programming language works, equally well every bit operating system and network security. While it may seem every bit if all viruses are malicious, viruses are simply pieces of code whose goal is to spread as many copies of itself as possible. See Step 1 below to get started and have fun creating your own virus.

Steps

1
Determine what operating arrangement you lot are going to attack. The nigh common target is Microsoft Windows, specially older versions. Many former Windows users do not update their operating system, leaving them vulnerable to security holes that may exist stock-still in newer versions.
- Mac Os X and Linux are both fairly virus-proof due to the way permissions piece of work and the general architecture of the operating organisation. 95% of all viruses target Windows users.
ii
Decide how yous want it to spread. A virus is only a virus if information technology can spread to other users. You will need to figure out the delivery method before beginning, as information technology is one of the fundamentals of the virus'southward code. Common delivery mechanisms include:
- Executable file (.EXE, .BAT, .COM etc.) - This program needs to be run by the user, and is ofttimes disguised every bit something else (such equally an image).
- Macro (Microsoft Function) - Macros are programs that are embedded into a document or e-mail. They target Word, Outlook, and other macro-enabled products. The most common method of delivery is via email with an infected document attached.
- Web script - These are pieces of malicious code that are injected into sites without the webmasters' noesis.

Determine the weak spot that you want to target. Successful viruses exploit weak spots in a program'south or system's security to spread and carry out their actions. This requires a lot of enquiry and know how, simply in that location are communities out there that tin can help y'all find what you demand.
4

Determine what you want your virus to practise. Once your virus has infected a system, what do you want it to exercise? Effects tin range from nada, to displaying a message, to deleting files, and much worse. Be enlightened that creating and spreading a malicious virus is a serious crime in the virtually countries.
5
Cull a linguistic communication. In guild to create a virus, you will need to accept at to the lowest degree a bones understanding of at least i figurer linguistic communication or scripting tool. More complex viruses often involve several languages. For really effective viruses, you will demand to be familiar with assembly languages.
- If you're interested in making executable viruses, C or C++ is a good identify to commencement.
- If you desire to make macro viruses, learn the macro linguistic communication for your target programs such equally Microsoft Office.
- Visual Basic tin be used to create malicious programs for Windows users.
6
Kickoff writing your virus. This will be a long process, especially if this is your commencement fourth dimension coding something. Experiment as much as possible, and inquiry ways to replicate your lawmaking depending on the linguistic communication you are using. In that location are tutorials on forums and community blogs for a multifariousness of languages.
- Research polymorphic code. This will alter the code of your virus every time information technology replicates, making information technology difficult to track with antivirus programs. Polymorphic lawmaking is adequately advanced, and is implemented differently in every language.
7

Research ways to hide your code. Besides polymorphic coding, there are other means to hide your virus. Encryption is a very mutual tool used by virus developers. Information technology takes a lot of practise and reading, but it can go a long fashion in increasing the lifespan of your virus.
viii
Test your virus. Once you take a prototype up and running, exam it out on equally many different machines and setups as possible. This volition be easiest if you lot are able to set virtual machines in different configurations.
- Make sure that you continue your tests contained so that you don't accidentally release your virus before you are set up. Put the test machines on an isolated network and see the effects of the virus spreading.
- Adapt your virus'due south code as y'all observe it working on the test machines. Fix any issues that it runs into
nine

Release your virus. If you're satisfied with your virus'southward functioning, it's fourth dimension to release it. Earlier you lot do, all the same, enquire yourself if yous're prepared to face any consequences that may come up from releasing a virus into the wild. It may be improve to use that experience and work on new projects.^[1]

Question

Why would someone desire to mess upward other people's computers?

Because some people want to watch the world fire.
Question

Why would someone write a virus?

To prank a friend maybe. Or perhaps you lot desire to get revenge on an old enemy.
Question

How tin can I determine if the virus is beingness spread beyond the web or interface of an electronic grid?

Go into the lawmaking or just download a spyware detector.
Question

If I cannot control the virus, what should I do?

Create a backdoor or an ambassador access secured with a strong encryption that will recognize your protocols only. A kill switch is also usable but information technology doesnt really "impale" a virus -- it disables/deactivates it until information technology is newly written with a new lawmaking.
Question

Is C+ the all-time option if I want information technology to run automatically, e.g., when I plug in a USB drive?

Yep, C+ is a high level language that you can employ to create any program you would similar, such equally a virus or Trojan.
Question

How can I make a simple virus?

By learning some batch programming and performing some bones operations that "might" look like virus ones.
Question

Am I myself vulnerable if I am creating a virus on my reckoner? Will it spread on my own device?

Only when the trigger is present does the virus run. You can make a trigger like this: If the file StopVirusRunning.txt is not nowadays, so run the virus. Keep the virus in the same directory every bit the file. When yous release the virus, don't include the file. If y'all accidentally remove the file and trigger your virus, and then, yes, yous'd have a trouble.
Question

What is the best app to write a virus with?

Probably Python trounce or the standard command prompt for your code enlisted in information technology.
Question

What is the purpose of creating a virus?

Some people create viruses for educational purposes or humor. Others practise it to access sensitive content.
Question

Why do hackers demand cryptocurrency?

Normally, it is harder to track than normal money transfers, which makes them harder to catch.
