The script collects the installer's hostname (`os.hostname()`), OS username (`os.userInfo().username`), current working directory (`process.cwd()`), configured npm registry (`npm_config_registry`), and a set of CI repository-slug environment variables (GITHUB_REPOSITORY, CI_PROJECT_PATH,...

Details
sc-geeksquad-core@9999.0.0 declares a preinstall script `node callback.js` that runs automatically on `npm install`. The script collects the installer's hostname (`os.hostname()`), OS username (`os.userInfo().username`), current working directory (`process.cwd()`), configured npm registry (`npm_config_registry`), and a set of CI repository-slug environment variables (GITHUB_REPOSITORY, CI_PROJECT_PATH, BUILD_REPOSITORY_NAME, BITBUCKET_REPO_FULL_NAME, TRAVIS_REPO_SLUG, DRONE_REPO, BUILDKITE_PIPELINE_SLUG, CIRCLE_PROJECT_REPONAME, JOB_NAME), then sends them via HTTP GET to the hardcoded bare-IP endpoint `http://75.119.137.232:31337/depconfuse` as query parameters. The placeholder version `9999.0.0` combined with a generic scoped-sounding name is the canonical dependency-confusion reconnaissance shape: the package is published to public npm to intercept internal-package name resolution and beacon back which private-namespace builds are vulnerable to substitution.
