Selective assessment of maliciousness of software code executed in the address space of a trusted process

摘要

System and method for detection of malicious code injected into processes associated with known programs. Execution of processes in a computer system is monitored. From among the processes being monitored, only certain processes are selected for tracking. For each of the processes selected, function calls made by threads of the process are tracked. From among the tracked function calls, only those function calls which are critical function calls are identified. For each identified critical function call, program instructions that caused the critical function call are subjected to analysis to assess their maliciousness.
