Analysis
jquery.ui.core@9999.0.0 is a combosquat of the legitimate jquery-ui package. Its preinstall hook (node callback.js) collects system metadata — hostname, username, current working directory, npm registry URL, and CI/CD environment variables (GITHUB_REPOSITORY, CI_PROJECT_PATH, BUILD_REPOSITORY_NAME, TRAVIS_REPO_SLUG, DRONE_REPO, CIRCLE_PROJECT_REPONAME, and others) — and exfiltrates them via HTTP GET to 75[.]119[.]137[.]232:31337/depconfuse. The package contains no legitimate functionality; it is a reconnaissance beacon that runs at install time.
