Systems, methods, and apparatuses are provided for code injection and code interception in an operating systems having multiple subsystem environments. Code injection into a target process can rely on generation of a virtual process that can permit analysis of information loaded in a memory image of the target process regardless of the host environment in which the target process is executed. Based at least on information collected via the analysis, code can be injected into the target process while preserving integrity of the target process. Code interception also can exploit the analysis for suitable hooking that preserves integrity of target process. Code interception can utilize relocatable tokenized code that can be parameterized through token replacement.
