The following modal dialog prompting for a software update password has been popping up a few times and I really do not know what to make of it:
- it seems to be controlled by the Finder (not a browser or any particular app)
- it does not seem to be part of the standard macOS update workflow, but coincidentally, there is an update available (as seen in my System Preferences)
- I cannot find a single hit on Google for the exact wording in that modal
- It seems plausible that it could come from one of the (very few) system extensions I have installed, but no indication of which.
Any idea how I could confirm whether this is legit (although horrible UX) or Malware. And if the latter: how could I go about finding the source (the fact that this pops-up would indicate that the system is already partly compromised).
