I once inherited a compiled executable. And source code that was demonstrably older than the binary. It was written by a contractor, who was blackmailing us for the up-to-date source code. In an FDA-regulated industry. How did we deal with it? We pretending nothing was wrong, and prayed that no show-stoppers would happen. We begged for permission to rewrite, but it was deemed to be too expensive. And I left that company as soon as I could.
