This could go very bad for Sonos. Imagine a virus that looks for Sonos devices on a network and bricks them all via "recycle mode"! The API probably isn't even locked down. I think it's unauthenticated SOAP/UPnP. An even dumber attack: guests with your wifi credentials can download the Sonos app and break your gear. It's entirely unauthenticated.
Im in the market for sound equipment. I just crossed these guys off my list.
But then they started removing functionality from their app, and the Play 1s don’t even work with the iPhone anymore unless you have a streaming service or you set up a music service. The ability to just play music and then play it on your speakers is gone. And they don’t give a fuck. They are completely unapologetic and they just forget about their older speakers like a bad habit and that’s why I will never buy another one again.
And their app is getting worse, they are forcing logging in to monitor your usage, etc. It’s infuriating. Their technology was amazing 5 years ago but now it’s annoying.
