The exfiltration fires on any import of the package. Additionally, the module exports factories named after Wix Thunderbolt internal registries (thunderboltRegistry, siteAssetsRegistry, editorRegistry, corvidRegistry) and ships a registry-manifest.min.json pointing at static.parastorage.com/unpkg/minimal-a11y-contrast-check@1.0.0, impersonating internal Wix build infrastructure to be resolved via dependency confusion. A hardcoded 'internetbrands' tag embedded in the exfiltration payload indicates targeted reconnaissance.\n\n---\n\nCredit: OpenSSF ([source](https://github.com/ossf/malicious-packages/blob/ae1e","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T23:18:22.416Z","source_updated_at":"2026-10-05T00:30:39.000Z","source_disclosed_at":"2026-10-05T00:30:38.000Z","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"}
