Keyloggers for example.

Linux always has been a system were the existence of malware was ignored, specially Desktop, contrary to other OSes (tooling included). But since a couple of years ago can be observed (I observe) slooow movements trying to correct this colossal mistake.

If this is the best way to do it or not, I do not enter. I particularly just welcome most of the advancements about this matter in Linux due such absence of worrying, keeping my fingers crossed that the needed tooling arrives on time (ten years behind Windows, I think).
