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.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.433Z","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"}
