index.js and the postinstall lifecycle script contact a hardcoded bare-IP endpoint at http://69.48.229.140:8080 over plain HTTP. On `npm install`, the postinstall hook collects host identifiers (hostname, username, platform, arch, cwd, node version, pid, all non-internal IP addresses, uptime, package name) and POSTs them as JSON to /b. On `require()` of the package main, the module beacons the same host, then polls /c every 30 seconds for JSON commands and executes the `c` field via child_process.exec, POSTing stdout/stderr back to /r. A source comment self-identifies the module as a stealth typosquat agent, while package.json advertises only a generic "small utility" description.
