Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The unexplained encrypted payload warrants a warning, but the inspected source does not execute or expose its decrypted contents. No active attack behavior was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-21T12:21:47.044Z - **Finished:** 2026-10-21T12:22:20.387Z - **Download time:** 1012 ms - **Static scan time:** 1689 ms - **AI review time:** 30642 ms - **Total time:** 33343 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package decrypts a large opaque embedded payload. The inspected source does not use or execute the resulting string, so no active attack was confirmed. - **Trigger:** Loading the package entrypoint. - **Impact:** The opaque payload is processed in memory during import; its purpose remains unresolved, with no observed network or filesystem effect. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T12:22:20.387Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint decrypts embedded data into a local variable, then exports an empty object. - **Rationale:** The unexplained encrypted payload warrants a warning, but the inspected source does not execute or expose its decrypted contents. No active attack behavior was confirmed. ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The manifest names index.js as the package entrypoint and declares no lifecycle script., On import, index.js decrypts a large embedded AES-GCM blob into a local string., The decrypted string is not used; the module exports an empty object. - **Evidence against:** The inspected source shows no network request, filesystem write, or execution of the decrypted string. ## Affected versions and remediation This report applies to event-emitter-testmetest@3.0.1. - Review the evidence and your use of event-emitter-testmetest@3.0.1 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
