My mistake, I just assumed their Byfron anti-cheat is kernel level because that's the most common reason why anticheats take issue with Wine. If their anti-cheat operates entirely in usermode, then their decision to block Wine is even more baffling to me.
- vablings 2mo agoIt is not kernel level, they use a number of pretty fancy user mode tricks to prevent people messing with the game. They encrypt every page and register an exception handler that decrypts the page when a fault is reached to keep memory secure. They do cache timing checks to see if a page was recently in the working set outside of the expected control flow and will flag you if you fail the check too many times because it indicates tampering.
- not_a9 2mo agoWhile the page decryption trick should work in Wine just fine (ZeroIT Lab Theia does that too, right?), I don’t remember if Wine provides workingset info like Windows.
- vablings 2mo agoYes, it does. Wine lets you register a VEH. They do other stuff to prevent Wine and virtual machines in general that I am not fully aware of. Even then it's just a fancy party trick, you can suspend the process call the decryption function enumerating all the pages and take a full dump to get the binary FYI; Theia is a very bad product. It absolutely tanks binary performance and does little to prevent a moderately competent engineer from cheating in your game.
- not_a9 2mo agoAre the other Zero IT Lab products like their code virtualizer of similar quality to Theia? My only exposure has been that one RE//verse presentation and shitposts on UC.
- vablings 2mo agoI can't speak for all the products, but from what I have heard it's pretty bad. Pay close attention to the shitposts on UC, they regularly get taken down but have some interesting information in them.
- nekitamo 2mo agoI personally liked their Code virtualizer. And it's under active development. Sorry to hear about Theia, I haven't run into it yet.
- nekitamo 2mo agoYes, Wine was (EDIT: partially) compatible with the Roblox anti-cheat, and there was a period in time where Roblox with its anti-cheat ran on Wine. Eventually, however, a decision was made to block Wine. EDIT It looks like the Roblox anti-cheat devs themselves explained why Wine was blocked: https://devforum.roblox.com/t/roblox-on-linux-everything-summarized-in-1-post-updated/3236696/42 https://devforum.roblox.com/t/roblox-on-linux-everything-sum...
