Microsoft responds to LG monitors installing McAfee ads on Windows (arstechnica.com)

Most "Smart" TVs use Automatic Content Recognition (ACR), essentially taking snapshots every 10+ms of what you watch and hear, then forwarding & selling that data to companies for ads, etc. I now feel it's only a matter of time before this "feature" finds its way to our ever "smarter" PC monitors.

LG with the help of Windows is already installing adware when the right Device ID is detected.

What is the symptom of a Linux machine being attacked by this? What can even happen? Doesn't the operating system need to support whatever is being installed, and also allow it to happen?

    To play devils advocate for them, if whoever is packaging fwup for the monitor either doesnt catch LG packaging malicious shit with it, or is for some reason allowing it to happen, it could happen.

    but then you'd have the wrath of at least a thousand enraged linux nerds on your ass and their stock would probably get tanked for a day.

    But I'm saying, what path does the installation take in order to even end up on disk? How would it get permission to run sudo/doas or gain root access in order to install shit, without my user/admin input?

    Most linux distros have a program called fwupd that installs hardware related updates. That was my example of the way in because most hardware updates are proprietary.

    Discover has shown me a UEFI update before in the list of updates its wants to do and ive confirmed it. If people aren't paying attention to updates and just updating its very much possible they could get something like that accidentally

    For example, AMD recently removed RAM encryption without telling anyone via an update.

    Technically, Ubuntu counts as they have had some ads for commercial (even closed) services. Assuming you wanted to set up your system as pure as possible.

    The OS itself doesn't generally know if the upstream organization pushing updates has broken their promises or not.

    Did those ads show up because of something a monitor chose to install?

    Not that time, but some Linux distros can also pull additional software automatically for connected hardware

    The whole point of this comment thread is that Linux is or isn't supposedly immune to this type of attack. Has this ever happened to a Linux machine that anyone knows of, that a monitor has installed software like this? If not, I think it's safe to say we can recommend Linux over others.

    I don't get it, what does the xz lib being attacked have to do with delivering and installing software on Linux, by the command of a connected monitor? Feels like a different kind of attack surface, or? Pardon my ignorance.
