    Unfortunately, it's macOS's built-in decompression/unarchiving code that is automatically invoked when you double-click on a .zip file (or other archive file) in the macOS Finder (filesystem browser). That code is probably also used in iOS and iPadOS, so decompressing zip files in the Files app in iOS and iPadOS probably doesn't check checksums either.
