  • Intercepting subroutine return in unmodified binaries
    Patent number: 9129062
    Abstract: Systems and methods for instrumenting code are disclosed. The entry to a subroutine is trapped and the subroutine's return address is mutated to create an invalid instruction pointer. The mutated return address is stored in the architecture reserved space for the return address. An exception handler is executed that has been instrumented to handle the fault caused by the mutated return address such that the exit from the subroutine is instrumented.
