Roku activated itself and someone is trying to send a message
Bought a Roku for my parents. They just called me, rather upset...they were watching regular cable on HDMI 1, all of a sudden the TV changes itself to HDMI 2, which is their Roku, and a message popped up on the screen that their next door neighbor is trying to send them a message. What could possibly be going on? I have my own Roku and nothing like this has ever happened to me. They now want to disconnect and pitch their Roku...
Re: Roku activated itself and someone is trying to send a message
Several possibilities come to mind:
1) Roku was compromised prior to purchase, have device details, allowing access/onscreen messages
2) Roku was activated through scam/fraud site/service, have device details, allowing access/onscreen messages.
3) Parents WiFi/Home Network has no/weak password and/or is compromised, allowing access/onscreen messages.
4) Screen sharing was used by someone nearby, doesnt require network access, allowing onscreen messages.
Roku devices (and other streamers/CE, to be fair) have little to no (and broken) device security, so once someone has access to the network all sorts of mischief and shenanigans can be had. WiFi Direct functionality allows non-network access, making it even easier.
They should check/change their WiFi password(s), and disable any screen sharing/Miracast/WiFi Direct functionality and limit network access (somewhat broken):
