ABSTRACT:
A method of enhancing the functionality of operating systems by providing an interface between the operating system and new, enhanced functions is described. This is done by intercepting calls to global functions. The first few instructions of a global function are overwritten with an instruction to jump to an interceptor function. When jumped to the interceptor function which calls a monitoring function, which performs some analysis and enhances the functionality of the operating system. Afterward, the interceptor function returns to the global function.
