Abstract
A method and system are provided that override constructors such that the constructors not only initialize objects but also provide notification about virtual pointers of the objects. This notification is provided to a list that stores which virtual pointers are created and where they are supposed to be pointing. By knowing the address of the virtual tables that the virtual pointers are supposed to be pointing to, a determination can be made whether the virtual tables are the correct virtual tables or whether they may be different virtual tables that have been substituted in by a hacker and that contain pointers to foreign code.
