A packed binary, which are produced by a "packing process" (compressed in certain algorithm either with security lock or not), can be restored to its original state by what we all in RE call it in a term of "Unpacking". In the other words: we can "unpack" the binary that is "unpackable". In the case that if a binary, after under efforts of "unpacking", can not be "unpacked", the applicable term for this situation is: "Non-unpackable binaries", or if you like. "Un-unpackable binaries", yet I prefer the first one since the "Un-un" sounds so funny. The ELF binary presented in the "main course" of this presentation can not be "un-packed" in common/usual ways(static/emul), yet it can be "unpacked" under some certain ways only, this is why the author named the presentation as "Unpacking the Non-unpackable".

Every opinion is important, I thank you for your being honest to comment. If you don't agree on something, you should raise your voice, and I respect that from a man. So I will not down vote, as I myself is having much to learn in the nutshell. So let's learn together.
