But you can detect serverside (at least probabilistically) if a user is abusing it to their advantage.

Some Valve guy gave a great talk about their cheating detection a while back; I found it incredibly impressive: https://youtu.be/ObhK8lUfIlc (can't comment on their effectiveness these days, haven't played CS in a long time)

The problem with building a secret profile on players based on undisclosed metrics is that could be flagging legitimate programming tools as "risk". What if a programmer who likes to hack and mod other games decides to play a Valve game? You don't know how their "risk" score is calculated.

For example, I've seen other programs refuse to run if you had Sysinternals Procmon running, or various standalone debuggers. Would you be deemed a "risky" user if you used tools like that?

Having watched that video, their newer ML-based anti-cheat does not seem to rely on inspecting running processes. It is based on data surrounding when a gun is fired in the game (a certain number of ticks before and after), and the classifier is initially trained on human-reviewed "killcams." But the classifier probably takes into account other data too, for example new Steam accounts with only CS in it would probably be classified as "high risk." On the other hand someone who has had their account for a long time and has paid games in it is far less likely too cheat.

That video is a fraud as far as I can tell. Playing cs in high elo's is more than 50% of the matches with cheaters. I played with a team of cheaters one time that was even blackmailing the opposing team for real money, and they got it, and blackmailed again, than they disabled cheats. This is a whole industry. That was one of the last times I played. I actually encountered the same cheaters a few days later.

As impressive as it sounds, the game is riddled with people cheating
