When processing the result of "unzip" in CyberChef, for example with YARA rules, all files contained inside the ZIP file, are concatenated together.

This is not a problem when dealing with a single file inside a ZIP container. But it can be for multiple files. If you want to know more, I recorded a video with more details:
