One common technique to hide malware in legitimate-looking files is to use file binders or packers. These tools can combine the malicious code with a legitimate file, such as a PDF or a Word document, making it difficult for antivirus software to detect the malware. Another method is to use steganography, which involves embedding the malicious code within an image or audio file. This way, the file appears normal to the user, but the malware can still be executed when the file is opened.
