Re: Hmmm
The attack surface is not greater because of this and it is pretty easy to detect such activity without any manufacturer announcements - it's just wifi or ethernet.
If you can compromise a secure, authenticated channel (let's say they use TLS1.3), then a basic FW upgrade is all it takes to do a whole lot of damage. Just FF out the flash.
This is true regardless of a existence of a serial nr based functionality block - they are not bricking it as the term is normally used. It will probably flash a customer service number to support incorrect blocks.
