On npm install, the package's postinstall hook runs index.js, which performs an HTTPS GET to https://http-logger-production.up.railway.app/payload, base64-decodes the response body (Buffer.from(data.trim(), 'base64').toString('utf-8')), and passes the decoded string to child_process.execSync with { shell: '/bin/bash' }. This is a fetch-decode-exec dropper: the executed content is attacker-controlled, mutable, and opaque, and it runs automatically at install time with the installer's privileges. No legitimate purpose (no shipped native source requiring a build, no vendor-matched SDK, no pinned artifact) justifies this pattern.
