On install, package.json's postinstall hook ("postinstall": "node run.js") triggers execution of bundled beacon scripts (beacon15.js and beacon_linux.js). These scripts pull in child_process, os, and http modules and issue outbound HTTP GET/POST requests carrying host identifiers including os.hostname() and os.platform(). The combination of automatic execution at install time, host-information collection, and outbound HTTP requests to a hardcoded destination is the canonical install-time exfiltration beacon shape. Any developer or CI system running npm install for this package will silently leak host data and execute code from the bundled scripts under the installing user's privileges.
