steam does not verify much by itself, its not made to be a strong security system. look up goldberg emu, cream api, etc. they work if the DLC content is not really downloadable, but already baked in just locked away behind a check
and if the content is something to download, most of the time you can grab the clean steam files from a website of a russian counterstrike community and drop the files into your game install folder and then use the aforementioned tools.
