Advisory PublishedCVSS 9.6/10
Obfuscated malicious NuGet package with no obvious purpose. Supply chain attack using intentionally obscured naming 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.
