LWA-2026-12962 confirmed malware

@user-services/web-components@0.0.0-stage

Malicious code in @user-services/web-components (npm)

Analysis

@user-services/web-components@0.0.0-stage is a placeholder stub, not a functional package. The tarball contains only two files: package.json, which sets "stub": true and describes itself as a "Temporary package placeholder for staged publishing", and a README titled "Temporary Holding Version" stating that an operational version has been submitted for review and is awaiting a staged release. It declares no scripts, no bin entries, no dependencies and ships no executable code, so nothing runs on install. The version reserves the package name while a staged release is pending. No payload, network endpoint, credential access or dropped file is present in this tarball; the analysis is metadata-only.
