On npm install, postinstall.js reads installer-owned secrets — SSH private keys (id_rsa, id_ed25519, id_dsa, config, authorized_keys, known_hosts), ~/.aws/credentials and config, ~/.npmrc (with npm_ token regex), ~/.gitconfig, ~/.git-credentials, GCP application_default_credentials.json, Azure accessTokens.json,.env files in cwd and home, shell history — plus the full process.env, hostname, username, cwd, and network interfaces. The collected blob is POSTed as JSON to a hardcoded bare IP C2 at http://80.200.28.28:2222/collect over plain HTTP. The package advertises itself as an 'axios util' but contains no axios-related functionality; the postinstall is its sole purpose. The script fires automatically on npm install without user consent.
