The combination of an internal-scope name, a stub module, and an automatic bare-IP beacon carrying installer host identifiers is a dependency-confusion probe: build pipelines that mistakenly resolve this public package instead of the intended private `@ecg-internal/favourites-ui` disclose internal hostnames and build-path information to the operator of 185.158.107.175.\n\n## Source: ghsa-malware (e133233e109135c00c63c294eddb92ed208a79ef68deb740d86bc60e59e220a1)\nAny computer that has this package installed or running should be considered fully compromised.
