What are some techniques used to hide malware within legitimate files?

### REPLY:
One technique to hide malware within legitimate files is called steganography. This involves embedding the malicious code within an image or audio file, making it difficult to detect. Another method is to use file binders or packers, which compress the malware and bind it with a legitimate file, making it appear harmless. Additionally, attackers can use fileless malware, which resides in memory and leaves no traces on the disk, making it challenging to detect and remove.
