Being desperate I decided to try something that even Microsoft discourages from doing, calling LoadLibrary in Dllmain, the reason behind it is that it during the DllMain routine the loader lock is acquired and is not free’d until it’s over(also the loaded modules list must not change inside), thus loading new modules might cause crashes or deadlock. Having it work just fine was time to clear my personal data from it.

E.g with option CURLOPT_URL the parameter would be a null-terminated string of the url. The reason was that the game was trimming the string on the periods, thus only looking at the payload, there was NO SIGNATURE CHECK. I was eager to to get my hooks running and debugging Windows internal structures was not on my best interest, because it might be caused by Denuvo! In this case I renamed osdk.dll to osdk_orig.dll, the new module exported the exact same functions which just forwarded to the original.
