My brother claims that Vanguard for League can do the same to gaming PCs that install it as CrowdStrike did to businesses who installed that, is this true? Does Vanguard have as much access/power?
Helldivers 2 does the same thing. If this continues it will be extremely advisable to move any non-gaming use-cases to a different computer as you have no idea what the "anti-cheat" is doing with that level of authority over your computer.
That works until all* games come with root level anti cheat. It was the same with micro transactions which people still defend despite being utter shit.
Realistically this will never be 100% but it will be enough of the mass market AAA games like CoD etc to mean that if you functionally want to play a game made in the last X number of years you will need to accept this or stop playing games altogether. I think most people will continue to play games. Most people will continue to install root level anti cheat, knowingly or otherwise, and all of them will get fucked by an exploit of that software. They may never even know about it.
This is pretty much what I’m afraid of. Even my knowledgeable friends dismissed the implications of a root kit so they could play Helldivers. Like 2 months later and they’re sick of it, and the damage is done. That game was a massive success despite what should have stopped everyone in their tracks.
Proton is not actually sandboxed the way an actual container is.
A) if the program running in proton was given root access in some way, say by tricking people into entering their root password for a claimed update, it would have complete normal control of your entire system just like normal.
B)apps running in proton still have access to the regular file system.
