Abstract
A system for stealing interrupt vectors from an operating system. Custom interrupt handler extensions are copied into an allocated block of memory from a kernel module. Also, operating system interrupt handlers are copied into a reserved space in the allocated block of memory from an interrupt vector memory location. In response to copying the operating system interrupt handlers into the reserved space in the allocated block of memory, custom interrupt handlers from the kernel module are copied over the operating system interrupt handlers in the interrupt vector memory location. The custom interrupt handlers after being copied into the interrupt vector memory location handle all interrupts received by the operating system.
