Vanguard, the controversial anti-cheat software initially attached to Valorant, is now also coming to League of Legends.
Summary:
The article discusses Riot Games’ requirement for players to install their Vanguard anti-cheat software, which runs at the kernel level, in order to play their games such as League of Legends and Valorant. The software aims to combat cheating by scanning for known vulnerabilities and blocking them, as well as monitoring for suspicious activity while the game is being played. However, the use of kernel-level software raises concerns about privacy and security, as it grants the company complete access to users’ devices.
The article highlights that Riot Games is owned by Tencent, a Chinese tech giant that has been involved in censorship and surveillance activities in China. This raises concerns that Vanguard could potentially be used for similar purposes, such as monitoring players’ activity and restricting free speech in-game.
Ultimately, the decision to install Vanguard rests with players, but the article urges caution and encourages players to consider the potential risks and implications before doing so.
Oh yeah, and for behaviour detection of this, it’s kinda annoying they don’t detect it because I don’t think it would be difficult to do this (either from a problem solving perspective or the amount of computational power that would be required).
Just track the x and y deltas and their derivative over time (in this case, the derivative is just the difference between the current sample and the previous one, so no calculus required, just a subtraction per sample). Then check if they are continuous. X and y deltas are velocity, which must be continuous because the mouse is a physical object and subject to inertia. Acceleration should also be continuous because of the limitations of our muscles (though if your mouse bumps your keyboard or your hand is moving and bumps your mouse, you can see natural acceleration that isn’t continuous, but these wouldn’t directly preceed a successful shot at a target).
Then just watch for spikes in either of those. A better cheat program could smooth the spikes, but it slows down the capability of the aim bot.
