System Randomly Disarmed Itself

I just randomly heard my base station saying that my alarm was disarmed which is pretty creepy (especially at night). I checked the app timeline, and it said it was disarmed by "remote". What would cause this to happen? I was just a few feet away from the key fob at the time, and I did no touch it. Also, it looks like it says "key fob" in the timeline when the key fob is used. I seems like this could have only been done by Simplisafe which is pretty concerning.
