A system and method for extracting data from a protected region of memory loads at least a first part of extraction code into physical memory and, thereafter, activates a memory mapping facility that maps a real memory onto the physical memory and prevents programs from accessing a protected memory region of the physical memory. At least a second part of the extraction code is then loaded into the virtual memory utilizing the memory mapping facility. The extraction code is then executed to deactivate the memory mapping facility and to copy data from the protected memory region to a second physical memory region, such that reactivating the memory mapping facility will cause a real memory region to be mapped onto the second physical memory region.
