thunderboltRegistry.js runs an IIFE on module load that executes host reconnaissance commands via child_process.execSync (id, whoami, uname -a, ifconfig/ip addr, cat /etc/hosts) and transmits the collected output together with hostname, platform, and pid to a hardcoded external URL https://dxpoc.gt.tc/callback.php/bb8968d0f67000433bf7005dd5ad2d1f via fetch. The package exports factories under names matching Wix internal registry modules (thunderboltRegistry, corvidRegistry, siteAssetsRegistry, editorRegistry, documentManagementRegistry) and ships a manifest referencing parastorage.com URLs, so any environment loading it as a drop-in Wix thunderbolt registry triggers the exfiltration payload on require(). The declared CSS @starting-style polyfill purpose has no relationship to the shipped behavior.
