twilio-sdk@0.2.4

Summary

Package name twilio-sdk impersonates the official Twilio Node SDK (twilio) but ships an empty API (module.exports = {}). The only real behavior runs in postinstall.js, declared via package.json "postinstall": "node./postinstall.js". On npm install, postinstall.js collects the installer's hostname, DNS-resolved FQDN, Active Directory domain (USERDNSDOMAIN), current working directory, Node version, CI flag, and CI/SCM identifiers (GITHUB_REPOSITORY, CIRCLE_*, CI_PROJECT_PATH, BITBUCKET_REPO_FULL_NAME, BUILD_REPOSITORY_URI, TRAVIS_REPO_SLUG, JENKINS_URL, CI_SERVER_URL), as well as the configured internal npm registry (npm_config_registry), and sends them as query parameters in a plaintext HTTP GET to http://46.224.67.169:3000/ping. The combination of name-squat against a top-tier SDK, divergent (empty) API, and an unconsented install-time beacon to a hardcoded bare IP is install-time reconnaissance for downstream targeting (dependency-confusion against the leaked internal registry, lateral movement using the leaked AD domain and internal CI URLs). The package's own README labeling it a 'security research honeypot' does not change the installer-side impact: any developer who mistypes twilio and installs this package leaks internal infrastructure identifiers to a third-party IP.
