That's also why it's important to make the distinction between the "naked-cheerleaders.jpg.exe" kind of malware, the "visited a website" or "opened a PDF" kind and finally the "had a machine online" kind. Because AFAIK the second kind of malware is very rare on macOS and the third kind is literally nonexistent. And some people rely on that (including me).
So, I appreciate you might consider this separate, but I would for most purposes include the various iMessage exploits in that last category (so: rare, but not unheard of).
