Generating a Multi-OS Fully Undetectable Malware(FUD) and Analyzing it Afore and After Steganography

Malwares are the most potent and subtle methods to assault a victim's machine in the field of cyber security. Malware is defined by its intent and capabilities, and it is always evolving, making it tough to track. We can obtain a better grasp of malware and its structure by developing our own malware. Malware does pass through antivirus software on many systems, it is designed to bring down the system. It's more difficult to detect unknown malware than it is to detect recognised malware. By generating our own malware, we intend to increase the effectiveness of OSINTS, this could be achieved by creating a FUD malware, this can be done on multiple OS, and then the hidden data in steganography is embedded in the carrier file, such as a video, audio, or image, and then extracted later.
