By the way if you don't already know. By Linux defines. What lots anti-cheat things do are root-kits. Anything third party reaching into the kernel to alter its operation by intercepting functions or adding functions by Linux define is a rootkit. Taking over control of the SSDT alterations does alter the way the kernel operates . So it is a rootkit. If game developers want features like this they would have been designed into the kernel. What happens when user installs two games that do SSDT monitoring. Possibly OS death. This stuff is highly unhealthy. Rootkits allow applications to interface with more than what they normally would be able to. Yes userspace interfacing with SSDT is normally impossible by windows NT design. We are better if users boycott games like that fernandocarvalho.
