A file in my dropbox account was edited apparently my me, at 3am (while I was asleep). How can I look into this and get information on what happened here?
You can review the activity on your Events page, and you can check the devices and web sessions linked to your account on your Security page. If you believe your account was compromised, you should (obviously) change your password as well, before removing any linked devices from your account. Also, you can look at the version history for the edited file to see what device the edit occurred on.
