Abstract

A DLL that includes an API hook is injected into the address space of a target computer process called by an application program. Upon termination of the application program, computer-readable instructions describing a process for filtering exceptions returned from the target computer process are stored in memory locations accessible to the target computer process and the DLL is ejected from the address space.
