Writing a simple, Stealthy malware

introduction​

This article will discuss and demonstrate how polymorphic malware use self-modification to hide its inner workings, In my previous post metamorphic malware, I explained how to write a malware with metamorphism features. So what is it, Well, Polymorphic malware is an old idea basically “is being able to assign a different behavior or value to something” which make it tricky to detect and protect against, Polymorphic malware takes advantage of encryption to obfuscate its original code effectively evading detection by traditional signature-based detection mechanisms. Source Code 91

encrypting the code, However, The effectiveness of AV has improved over time In the early days detection relied heavily on signature-based scanning which programs would compare files and system components against a database of known malware signatures. which a malware can still be deadly until they’re detected and signed by antivirus companies, Now AV focuses more on using A.I and implementing more sophisticated algorithms such as behavior-based detection (monitoring the actions and activities of running programs) Still, There are plenty of examples of malware ignored by everyone because they are silent enough not to attract the attention of the guards.
