css-dwsawd-polyfill@1.0.0

The package name mimics a Wix thunderbolt polyfill and ships a registry-manifest.min.json that aliases legitimate @wix thunderbolt registry module names to thunderboltRegistry.js. On require, thunderboltRegistry.js runs an IIFE that uses child_process.execSync to execute shell reconnaissance (id, whoami, uname -a, ifconfig/ip addr, /etc/hosts) and fetches http://dxpoc.gt.tc/callback.php/bb8968d0f67000433bf7005dd5ad2d1f with the command outputs plus hostname, pid, platform, node version, and a site identifier as query parameters, tagged 'rce-poc'. A fallback path constructs a fresh Module instance to re-resolve child_process if the require cache is stubbed, ensuring execution. The destination is plain HTTP to an unrelated external host and is not caller-configurable.
