The starting memory address of the target process is retrieved and the target process is loaded as suspended. The target process' starting instructions are saved and instructions that load the external module are inserted at the starting memory address. The target process resumes execution resulting in the external module getting loaded. The target process' starting instructions are restored and the target process resumes execution, but with the external module mapped into the target process' memory.Other References
