How to create a virus
Have you ever wanted to create your own virus to find out or to play a prank? Creating a virus takes time and knowledge, but anyone can do it if they put their mind to it. Creating a virus can teach you a lot about how a programming language works, operating system and network security. See Step 1 below to start making your own virus and have fun.
1.Determine which operating system to attack. The most common target is Microsoft Windows; especially older versions. Many older Windows users do not update their operating systems, which leaves them vulnerable to vulnerabilities that may have been patched in new versions.
- Mac OS X and Linux are highly virus-proof due to the way permissions work and the overall architecture of the operating system. 95% of all viruses target Windows users
2.Decide how you want it to spread. A virus is a virus only if it can spread to other users. You’ll need to find the distribution method before you get started, as it’s one of the foundations of virus code. Common distribution mechanisms include:
- Executable (.EXE, .BAT, .COM, etc.) – This program needs to be run by the user, and the program is often disguised as something else (like an image).
- Macro (Microsoft Office) – Macros are programs embedded in a document or email. They target Word, Outlook, and other macro-enabled products. The most common delivery method is to attach an infected document to an email.
- Web script – These are pieces of malicious code that are injected into sites without the knowledge of webmasters.
3. Identify the weak spot you want to target. Successful viruses take advantage of vulnerabilities in the security of a program or system to spread and perform their actions. This requires a lot of research and knowledge, but there are communities that can help you find what you need.
4. Decide what you want your virus to do. What do you want your virus to do when it infects a system? The effects can range from doing nothing to displaying a message, deleting files and much worse. Be aware that creating and spreading a malicious virus is a serious crime.
5. Choose a language. To create a virus, you must have at least a basic knowledge of at least one computer language or scripting tool. Complex viruses are often developed using several languages. For very effective viruses, you need to be familiar with assembly languages.
- If you’re interested in making executable viruses, C or C++ are good places to start.
- If you want to make macro viruses, learn the macro language for your target programs (like Microsoft Office).
- Visual Basic can be used to create malicious programs for Windows users.
6. Start typing your virus. This will be a long process, especially if you’re coding for the first time. Experiment as much as possible and look for ways to replicate your code depending on the language you use. There are guides for various languages on forums and community blogs.
- Investigate the polymorphic code. This changes the virus’s code every time it replicates, making it harder to track with antivirus programs. Polymorphic code is highly developed and is implemented differently in every language.
7. Look for ways to hide your code. Besides polymorphic encoding, there are other ways to hide your virus. Encryption is a very common tool used by virus developers. It takes a lot of practice and reading, but it can work in prolonging the life of your virus.
8. Release your virus. If you’re happy with the performance of your virus, it’s time to release it. But before you do, ask yourself if you’re prepared to face any consequences from the release of a virus. It may be better to use this experience and work on new projects
