Abstract
An example method includes modifying, prior to run time, an executable file of an application to cause an operating system loader to load additional code using a dynamically-linked library. Modifying the executable file includes determining whether the executable file includes sufficient unused space to accommodate a load command, and adding the load command to the executable file when the executable file includes sufficient unused space by: shifting, in the executable file, an existing load command that does not contain dependency information to make space for the load command; or identifying unused space outside of a data portion of the executable file that can be removed to accommodate the load command. The additional code, when executed by a processor, causes the processor to change a pointer in a table that indicates an address of an imported function implementing a system call so the pointer indicates an address of a customized function.
