As is the case with fake codecs these days, the binaries are hidden and getting them depends on where the developer hides them. With certain sites, you can often get a sample through /download/(sitename).exe (there are always more binaries in the same directory as well, each numbered for affiliates). For other codec sites, /download.php?id=4082 will get a binary (that number is just an affiliate ID — other numbers work as well). If you are hunting for Mac fake codecs, remember to change your user agent to a Mac. And please — don’t touch these binaries unless you know what you’re doing, as they are live Trojans.
