What are some common techniques used to disguise malware as legitimate files or applications?

### REPLY:
One common technique to disguise malware as legitimate files or applications is to use file extensions that are commonly associated with trusted files, such as .doc, .pdf, or .exe. Another method is to use techniques like file or code obfuscation to make the malware's code difficult to detect or analyze. Additionally, attackers may use social engineering tactics to trick users into downloading or executing the malware, such as disguising it as a software update or a popular game.
