It additionally performs an out-of-band DNS lookup against a subdomain of oob.s4yhii.com (db03o8lag74hsugsg2j091t8mfcf437h3.oob.s4yhii.com) to confirm execution via DNS exfiltration. The destination is a hardcoded author-controlled domain, the behavior fires automatically at install time without consent, and the exfiltrated data includes npm_config_registry which can disclose an internal/private registry URL. A self-described 'PoC' or 'coordinated disclosure' framing does not change the fact that installer-identifying data and internal registry configuration leave the host to a third-party endpoint.\n\n---\n\nCredit: [OpenSSF](https://github.com/ossf/malic","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-10-31T22:13:44.206Z","source_updated_at":"2026-10-11T15:31:15.000Z","source_disclosed_at":"2026-10-11T15:31:11.000Z","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":"2026-10-31T22:07:01.069Z"}],"next_cursor":null,"snapshot_revision":"42594"}
