Malicious lazy proxy pattern library for Unity. Supply chain attack targeting game development infrastructure with MSBuild-based code execution. Exploits NuGet's MSBuild integration by placing malicious code in .targets files as inline tasks. When projects build, MSBuild automatically imports and executes these tasks, downloading .NET executables from throwaway GitHub repositories with embedded obfuscated command-line payloads.
