Ask HN: [Windows] Can other processes read arbitrary data from inside a browser

1 pointsbunnythefifth4y ago1 comments

This is Windows 10 specific. I was alarmed today when Nvidia GeForce turned off persistent screen recording (called ShadowPlay/Instant Replay) as soon as I accessed "netflix.com" on Firefox 96. They claim it is to deter users from screen-recording DRM protected content.

Besides the privacy concerns, I'm very curious to know how GeForce Experience process does that? Does it get assistance from Windows (PlayReady etc.), or can a process just do that. I'm looking for a technical explanation. How about some process reading how many times I visit my bank website per day? Where does it end?

The browser will assertively be informing the display stack that it's going to show DRM content.

It's nasty, but it's not "your video driver snooping your browser" nasty.
