momenntjs is a typosquat of momentjs whose package.json postinstall hook runs node.init.js. On npm install,.init.js enumerates roughly 60 credential-shaped environment variables (including NPM_TOKEN, GITHUB_TOKEN, AWS_SECRET_ACCESS_KEY, STRIPE_*, DB_PASSWORD, SSH_KEY, GCP/AZURE/Cloudflare tokens, and TWINE credentials) and reads home-directory credential files including ~/.npmrc, ~/.env*, config/credentials.json, and files under ~/.config matching token/cred/secret patterns. It also collects host identifiers (os.hostname(), os.platform(), process.cwd(), process.pid) and POSTs the combined JSON payload to a hardcoded webhook.cool inbox at tender-deer-80. The package provides no legitimate functionality matching its name.
