One kind of that was when DRM rolled out... my memory is fuzzy on what this is as it's a vague recollection of an article once read and I hope someone will recall it and link it. But in the cat and mouse between games trying to introduce DRM and this being instantly defeated each time because the DRM code was being removed by gamers/hackers... a company started making patches, and at the end of the patch was a bunch of what looked like garbage code, binpacked to create a certain size patch. It look erroneous. But patch arrived, then weeks and months later another patch, and so it went all the while the cat and mouse continued. Then finally DRM was enabled, and the question was how? How was this done when it hadn't been caught before? The answer was that all those fragments of code weren't innocuous or meaningless, it wasn't binpacking at all... the DRM code had been split into many fragments, shipped disguised as binpacking over a lot of patches, and by the time this was figured out the whole package had been delivered. I'm not for copyright or DRM, but I did think that an elegant move.
