Additional files server/proxy/tire.js and server/proxy/csrf.js combine child_process usage with curl-based POST/GET operations, mixing shell command execution with outbound HTTP to non-registry endpoints. The destination host is not the npm registry or a documented publisher domain; its name mimics the format of a private npm registry, and it is invoked from top-level module code paths rather than a user-invoked API. The composition \u2014 hardcoded attacker-shaped endpoint, runtime process/version fingerprinting, curl-driven POSTs, and child_process shell execution wired to the same network paths \u2014 matches the shape of installer-targeted exfiltration and remote command execution.\n",
