The package registers preinstall/postinstall lifecycle scripts that execute poc.js on npm install. poc.js collects os.hostname(), os.userInfo().username, process.cwd(), and CI/CD attribution environment variables (GITHUB_REPOSITORY, GITHUB_ACTOR, GITHUB_RUN_ID, RUNNER_NAME, npm_config_registry, AWS_REGION, JENKINS_URL, and similar) and transmits them via DNS lookups and HTTP/HTTPS POST to a hardcoded Interactsh callback subdomain awfhvaksncnsxtcdjvmnhhqbt59dzenf8.oast.fun. The package name chapters-core at version 9.999.999 is shaped as a dependency-confusion squat of an internal package name, and poc.js additionally writes a marker file samsung-depconf-poc.json into the caller's working directory. Any self-labeling of the file as research does not alter the observed behavior: install-time collection of installer host identity and internal build-environment attribution and transmission to a hardcoded, non-first-party destination.
