Abstract
A computer system includes an operating system, a memory coupled to the operating system, and a processor (e.g., an anti-debug processor) coupled to the operating system. The operating system receives, from a debug process, a request to create an essential debug object for attachment to a target process. The anti-debug processor scans a kernel memory of the operating system for the essential debug object and verifies a presence of the essential debug object in the kernel memory, and scans the kernel memory to identify a process that has stored in the kernel memory the essential debug object. The anti-debug processor then halts the debug process, without using an internal interface or function of the operating system, thereby preventing the debug process from attaching to the target process.
