This exists for CSGO. I know several people in the CSGO cheating scene that do this. (Note that it is OVERKILL for regular competitive matches, since VAC sucks, there are open source cheats that have been undetected for years. it's only worth it on third party anti cheat platforms like Faceit or ESEA).

However, a direct memory access (DMA) card that reads player positions from the RAM is more popular as it just requires an arduino between the mouse to overwrite some of the mouse movements to aim towards a head (in addition to the DMA card). it requires a few hundred bucks in hardware and skill in firmware to make sure the DMA card cannot be detected. But in exchange you play on a semipro level mostly undetected. Search "Project EPO" and "Lohouse" on youtube for more info; he's a real skilled programmer who even sent a build to a famous youtuber in order to bring awareness to it.

I was deep into the CSGO cheating scene, and yes, it is just as toxic and cringe as it sounds, 99% 14 y/o toxic skids.

No judging, but why?

I was a kid who always would try to break every system I came across, no matter what it was. I disassembled our FiOS fiber box when I was 11 just to see if I could get us onto the 1Gb plan somehow. I bypassed the "free beta over" modal on a major photo retouching program to get myself free $99 license keys when I was 12 (inspect elem ftw). I was just always in this mindset of "how do I get around this" even if there was literally nothing of desire behind it.

So naturally when it came to anti cheats, I spent a lot of time reverse engineering and had the same mindset. I never cheated against others in a way to benefit; sometimes to just troll, sometimes to joke around with friends, and occasionally I would be a dick to others who were being a dick as well. I started developing and contributing to other cheats and talking to other programmers as well. I still have a lot of the contacts, especially the people that sell thousands/$ cheats that get used by top 100 in country players (not pro, but tournament players)...

But I will be honest. It got really painful when I realized cheats that I contributed to were being used against my favorite youtubers. I know it sounds stupid, almost like doublethink, to watch and enjoy famous youtubers who vehemently attack cheaters while cheating myself. But in Tom Scott's words [0], "everyone draws the moral line of what's acceptable just slightly below what they're actually doing". But I've nearly entirely given up with playing the game because I have found far more enriching uses of my time, than doing something that actively harms so many people.

If you develop cheats, it's a challenging problem that you can make a good bit of money if you are successful. As for the users, some do it to win money in competitions, some just like to play on god-mode. It's definitely more prevalent in free games since there's no financial disincentive when you get banned. There are also other ways to cheat that aren't actually cheating, like smurfing where a good player just makes new accounts to play against low level players or intentionally loses higher level games to bring them back down to low-level games.
