Abstract
Methods and system for dynamically injecting execution logic into shared memory spaces of a windowed operating system. An injection dynamic link library is loaded from an injection application into a pre-determined memory location within an area of shared memory within the windowed operating system. A main dynamic link library function within an original kernel dynamic link library including kernel functions for the windowed operating system is located from the injection dynamic link library. A jump command is inserted from injection dynamic link library within the main dynamic link library function in the kernel dynamic link library to create a modified kernel dynamic link library. The jump command jumps to an injection hook function within the injection dynamic link library whenever a new windowed operating system process is created. The injection hook function within the injection dynamic link library includes multiple injection functions that are executed by the windowed operating system prior to executing any other software applications whenever a new process is created in a windowed operating system. The methods and system of the present invention allow execution logic to be …
