11/29/2022 0 Comments Unity3d obfuscator keygen crackAn obfuscated or encrypted metadata file.If the file fails to load with errors such as An item with the same key has already been added, Sequence contains no matching element or Index was outside the bounds of the array, there are a few possibilities, in this order of likelihood: Assuming you’ve found a metadata file with a valid header, try to load it into Il2CppInspector.If you don’t, the metadata file is likely – but not guaranteed – to be embedded within the game binary itself or another file, or it may be encrypted and stored as one of the other files. If you find one, it’s probably a renamed global-metadata.dat. If you can’t find global-metadata.dat in its usual location (Android: assets/bin/Data/Managed/Metadata/global-metadata.dat, PC: _Data/il2cpp_data/Metadata), scan all of the game files for any starting with the above magic bytes.If it doesn’t look similar to this, it’s probably obfuscated or encrypted. The start of an unobfuscated global-metadata.dat looks as follows – four magic bytes, a 4-byte version number and a list of file offsets and lengths for each table in the file – generally in sequential order. Are the first four bytes AF 1B B1 FA? If so, this is a good sign that the file is not obfuscated – but not a guarantee. Open global-metadata.dat in a hex editor.How do I know if global-metadata.dat is obfuscated? I’ll also throw in a couple of examples to whet your appetite. This will include obfuscated metadata, encrypted metadata, and metadata embedded in the binary itself, plus light obfuscation of the code path to the loader. In this tutorial, I’ll walk (swim?) you through how to find the loader for global-metadata.dat in almost any IL2CPP application so that you can reverse engineer it yourself. At least I think that’s how the adage goes… or was it fish something? Either way, we all started off as plankton hopefully you are thirsty to become a shark! The old adage of giving a person a tool and they’ll hack for a day, but teach a person to write tools and they’ll hopefully stop spamming your social media seems pertinent here. While it’s quite amusing to see narrowly targeted attacks percolate, it does make the support tickets pile up on the issue tracker, and I unfortunately have neither the time nor the desire to sit and pick apart every file thrown at me. Over the last few months I’m starting to see all kinds of weird and wacky obfuscation schemes designed to prevent Il2CppInspector from loading IL2CPP games.
