Malicious code in @uwr/colors (npm)
--- _-= Per source details.

The package's advertised functionality is a trivial 5-entry frozen color constants map under the unscoped-looking @uwr scope ("colors for the unified workflow runtime") with an empty author field, consistent with a dependency-confusion / reconnaissance probe staged against an internal namespace rather than a legitimate library.
