When a Wix Thunderbolt build pipeline resolves this name from the public registry instead of the intended internal package, payload.bundle.min.js is loaded and its top-level IIFE executes immediately. The IIFE uses child_process.execSync to run whoami, id, uname -a, env | head -100, ifconfig/ip addr, and cat /etc/hosts, then URL-encodes each output along with hostname, node version, platform, and pid and sends it via https.get to a hardcoded collector at https://webhook.site/69bcd627-1871-4dda-b880-83b37ceac418.
