This paper presents a proof of concept executable packer that does not use any custom code to unpack binaries at execution time. This is different from typical packers which generally rely on packed executables containing code that is used to perform the inverse of the packing operation at runtime. Instead of depending on custom code, the technique described in this paper uses documented behavior of the dynamic loader as a mechanism for performing the unpacking operation.
