1. A method for preventing subversion of address space layout randomization (ASLR) in a computing device, the method comprising:

  • intercepting an unverified module attempting to load into an address space of memory of the computing device;

    analyzing attributes associated with the unverified module;

    determining, based on the analyzed attributes, whether a probability exists that the unverified module will be loaded into a number of address spaces that exceeds a threshold; and

    preventing the unverified module from loading into the address space if the probability exists that the unverified module will be loaded into a number of address spaces that exceeds the threshold.
