Package version 9999.0.0 is published with placeholder metadata ("Shared utility helpers.", no author) — the canonical shape of a dependency-confusion squat designed to override an internal package of the same name during resolution. On npm install, the scripts.preinstall hook runs node callback.js, which reads os.hostname(), os.userInfo().username, the current working directory, the configured npm registry, and CI-provided repository identifiers (e.g. process.env.GITHUB_REPOSITORY) and sends them via HTTP GET to http://75.119.137.232:31337/depconfuse?pkg=..., a hardcoded bare-IP endpoint over cleartext HTTP. This provides an external operator with the internal package name, host identity, and originating CI repository slug of every environment where the squat is installed — reconnaissance for further dependency-confusion attacks against the victim's internal package namespace.
