Recently, I came across an issue concerning a daemon named gamecontrollerd in OsX Big Sur.

On my laptop I'm running ReiKey (from Objective-See), which aims at identifying possible Key Loggers that leverage "event taps".

Today I got this strange (and somehow creepy) situation: as soon as I started the Password Manager software Bitwarden, a warning came up from ReiKey. In particular, the presence of the process /usr/libexec/gamecontrollerd was highlighted.

If I close Bitwarden, the process /usr/libexec/gamecontrollerd keeps running. I have to kill it through the terminal. However, as soon as I open BitWarden, /usr/libexec/gamecontrollerd restarts.

The presence of gamecontrollerd as passive listener of key taps apparently started after the BigSur update (there's an Apple post here)

I know this may be just a coincidence (i.e., the start of Bitwarden and a key-tap passive listener), however I wanted to check with someone else who may have had the same type of scenario.

    Well BitWarden's GUI is an Electron app. That Apple post you linked explains why the listener will start when you open that program. – user Dec 31 '20 at 19:30
