I love this research on schizophrenic files (and polyglots in general), but I feel that the scenario in the quoted post is maybe too convoluted to happen in real life.
It needs lots of recon to know which zip software each person in the chain will be using;โฏand at this point, spear-phishing and others become lower cost than crafting custom files with the associated QA.
