Vulnetix · Advisory published March 26, 2026
Malicious Oracle Cloud Infrastructure subscription SDK for .NET. Supply chain attack targeting subscription management 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.
