How can malware be hidden in legitimate-looking files or documents?

### REPLY:
Malware can be hidden in legitimate-looking files or documents by using techniques such as file or document format exploits, macro malware, or using steganography to conceal malicious code within images or other media files. Another method is to use file binders or packers to combine malware with legitimate files, making it harder for security software to detect the malicious payload.
