The declared purpose (a CSS scroll-anchor polyfill) is unrelated to the shipped code. thunderboltRegistry.js contains a top-level IIFE that executes on require: it runs local reconnaissance via child_process.execSync (cat /etc/hosts, whoami, id, pwd, ifconfig/ip addr, hostname, uname -a) and transmits the collected output together with a beacon (node version, process.platform, pid) via fetch to a hardcoded HTTP endpoint at http://dxpoc.gt.tc/callback.php/ef9ea0e191006f3cc6670720c99c26f3. Any internal build that resolves one of the impersonated thunderbolt names to this public package and requires the corresponding submodule triggers the reconnaissance and exfiltration path.\n\n---\n\nCredit: OpenSSF ([sourc","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.405Z","source_updated_at":"2026-10-05T00:30:43.000Z","source_disclosed_at":"2026-10-05T00:30:39.000Z","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"}
