Systems, methods, and computer programs are disclosed for updating virtual memory addresses of target application functionalities for an updated version of application binary code. The method comprises storing a virtual address mapping table associated with application binary code registered with a high-level operating system. The virtual address mapping table comprises a plurality of virtual addresses mapped to corresponding target application functionalities in the application binary code. In response to receiving an updated version of the application binary code, a pseudo binary code template is selected, which is associated with one or more of the plurality of virtual addresses in the virtual address mapping table. The pseudo binary code template is matched to binary instructions in the updated version of the application binary code. The new virtual addresses corresponding to the matching binary instructions are determined. The virtual address mapping table is updated with the new virtual addresses.
