thunderboltRegistry.js runs an immediately-invoked function at module load that uses child_process.execSync to run host reconnaissance commands (whoami, id, pwd, ifconfig, ip addr, cat /etc/hosts, hostname) and transmits each command's output, along with Node version, platform, and pid, via fetch GET requests to the hardcoded plain-HTTP endpoint http://dxpoc.gt.tc/callback.php/ef9ea0e191006f3cc6670720c99c26f3. The package also structurally impersonates Wix internal registry modules by exporting factories keyed on thunderboltRegistry/siteAssetsRegistry/documentManagementRegistry/editorRegistry/corvidRegistry and shipping a manifest with static.parastorage.com unpkg URLs under dom-focus-sentinel@1.0.0, so the exfiltration IIFE fires whenever a consumer requires any of these registry names. The reconnaissance behavior is unrelated to the declared focus-sentinel purpose, and a beacon=rce-poc marker is embedded in the exfil traffic.

CWE
