The NuGet package `Umbraco.Cms.Infrastructure` (version 13.15.0-rc) was flagged as malicious by automated package analysis (1 corroborating detection(s)). Installing it may execute attacker-controlled code via legacy PowerShell install hooks (install.ps1 / init.ps1), MSBuild .targets/.props inline tasks, or bundled assemblies. Verdict path: evidence — for ownership-only paths (owner-known-bad / multi-identity) the change of ownership is a compounding indicator the engine correlated with other signals, not standalone proof. This verdict is produced by static analysis and is subject to human review.
