This paper describes a method of shared library call redirection using ELF infection that redirects the Procedure Linkage Table (PLT) of an executeable. Thus, redirection is not resident outside of the infected executeable. This has the advantage over the LD_PRELOAD redirection technique in that no environment variables are modified, thus remaining more hidden than previous techniques. An implementation is provided for x86/Linux.
