It started with an icon which appeared in my Safari browser which was that of Dropbox Dash (the blue squares).
When clicking it, it brings you to this page: https://app.getcommande.com/install which when visiting CLEARLY is a clone of Dropbox's look.
I downloaded the app and very quickly stopped myself from dragging the .app file within the downloaded .dmg into my Applications folder because it is very obviously not Dropbox.
Upon investigating how in the world this malware trap made it into my Safari browser, I noticed it was implanted by this .app called Dropbox Dash which looked like a legitimate Dropbox app. Naturally I removed any trace of it.
