There was an attempted burglary on my house last week, and I'm confident they knew I had Sonos equipment and cased my house specifically to steal it. I have a ring doorbell video of a guy come up to my front porch with a crowbar at 1:40PM in broad daylight, with two guys in the background -- one small enough to fit through my small windows and another to stay on the lookout.
The windows were locked and apparently the burglars were not able to pry them open and not willing to break them in broad daylight. I posted the video on Ring and did contact the police. I am in the process of beefing up security at my house.
My Sonos speakers are the only high value items in the house that a thief could easily use/sell after stealing. Sonos items could fit through a small window after simply unplugging them from the wall. I purchased them within the last year. I used the Enjoy service and I am suspicious someone who had access to their records tipped off the burglar.
Sonos -- you need to fix this problem, and you need to do it yesterday. No one would break in to steal my Macbook or iphone because they wouldn't be able to use them without the password and two factor authentication. You need to add a software update that requires two factor authentication if someone tries to setup the equipment on a different Wifi network. A simple software update like this would take your equipment from causing danger to those who own it from thieves trying to break into their houses, to keeping it enjoyable without anyone wanting to steal it in the first place.
Also -- I think you need to look at the Enjoy service in Denver, and consider shutting it down. I don't know how else the burglars would have been tipped off to my house specifically. They were casing my house and did this while I was on vacation so they obviously had a tip off somehow.
