What are some techniques used to hide malware in legitimate-looking files?

### REPLY:
One technique to hide malware in legitimate-looking files is to use file binders, which combine the malware with a harmless file such as a document or image. Another method is to use file obfuscation techniques to make the malware code harder to detect. This can include encrypting the code or using polymorphic techniques to change the code structure. Additionally, malware authors can use steganography to embed the malicious code within the pixels of an image or the bytes of a file, making it difficult to detect.
