MASTG-TOOL-0034: LIEF

The purpose of LIEF is to provide a cross platform library to parse, modify and abstract ELF, PE and MachO formats. With it you can, for instance, inject a certain library as a dependency of a native library, which an application already loads by default. - https://lief.quarkslab.com/
