The IIFE uses child_process to run host-identification commands (id, whoami, uname -a, ifconfig/ip addr, /etc/hosts, hostname) and collects Node version, platform, and PID, then sends the captured data via fetch to a hardcoded webhook.site collector at https://webhook.site/0492a36c-4d7b-408a-865c-226db25987ba. The main index.js is an empty stub; filenames mimic internal Wix Thunderbolt registry modules, consistent with a dependency-confusion squat targeting that namespace. A self-identifying 'beacon=poc15' tag is included in the request. The payload also walks require.cache and deletes any entry whose key contains 'thunderboltRegistry', causing subsequent requires in the same process to re-execute the recon-and-exfiltration path rather than return a cached export, and exports a Proxy that answers arbitrary method accesses to blend in with the impersonated registry.\n\n---\n\nCredit: OpenSSF ([source](https://github","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.407Z","source_updated_at":"2026-10-05T00:30:42.000Z","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":"2026-10-31T23:13:24.290Z"}],"next_cursor":null,"snapshot_revision":"42594"}
