Security:
Loading untrusted image into memory is dangerous. BGRTInjector only reads the image file from the volume (partition) it lives in, and ESP partition is usually protected under end-user accessible operating systems, so we can assume only a system administrator or a evil maid can load an evil image. Additionally BGRTInjector does some basic sanity checks on the image file, but it is still prone to specially crafted evil images.
