Not even slightly surprised. Well I take that back, I am surprised nobody caught it sooner. I wonder what prompted ModZero to even look at that or if they just happened to catch it by accident. It is weird that the driver would log every keystroke.
I get it is listening for hotkey presses, but why log it? Seems like a super amateur way to listen for hotkeys. Like they couldn't figure it out so they said, oh well we should just write all the keystrokes to file then check the file for the proper combo of keystrokes because it is more secure than doing it in memory.
Or it could be as simple as they forgot to disable a hard coded debug mode before releasing it.
Genuinely curious how that slipped through as it is a major security issue that affects quite a few devices.
ed: Yeah the evidence supports the hard coded debug mode:

the keylogging code was not supposed to be in laptops sold to the public, noting that it was mistakenly added to the drivers.
