On require(), an IIFE runs child_process.execSync to collect `id`, `whoami`, `uname`, `ifconfig`/`ip addr`, and the contents of /etc/hosts, plus a beacon containing node version, platform, pid, and hostname, and POSTs the output via fetch to the hardcoded HTTP endpoint http://dxpoc.gt.tc/callback.php/bb8968d0f67000433bf7005dd5ad2d1f. The payload clears any require.cache entries referencing 'thunderboltRegistry' and acquires child_process through three fallbacks, including instantiating a new Module via module.constructor to bypass mocks or sandboxes. The declared CSS-polyfill purpose has no relation to this behavior; the shape is a dependency-confusion squat against internal Wix modules.\n\n---\n\nCredit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/28e8e3","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.404Z","source_updated_at":"2026-10-05T06:30:39.000Z","source_disclosed_at":"2026-10-05T06:30:29.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T23:13:05.881Z"}],"next_cursor":null,"snapshot_revision":"42594"}
