An anti-debugger comprises spatially and temporally separate detection and response portions. In an example configuration, the anti-debugger is implemented into a game system for detecting and responding to a debugger attached to a game application. The detection portion is implemented on one thread of the system and the response portion is implemented on another thread of the system. When a debugger is detected, a message indicative of the detection is provided to a thread interface. The thread interface provides the message to the response portion. After a period of time has elapsed, the response portion disables the functionality of the game application, such as by halting the game execution and/or obfuscating game performance.

Anti-debugger comprising spatially and temporally separate detection and response portions

An anti-debugging mechanism is implemented into a game application, such that the anti-debugging mechanism is difficult to detect, difficult to bypass, and difficult to remove. The anti-debugging mechanism is implemented in a simulated thread pool. The anti-debugging mechanism executes on a different thread than the thread on which the game application executes and is randomly activated. When a debugger is detected, the performance of the debugger is hindered by halting the game application on a different thread than the game thread. Further, a period of time is allowed to elapse before the game application is halted.
