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 package has no automatic npm install hook, so the evidence does not establish an install-time attack. Its opaque, automatic global self-update capability is nevertheless a meaningful supply-chain risk that warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-22T06:42:17.374Z - **Finished:** 2026-09-22T06:52:18.289Z - **Download time:** 1530 ms - **Static scan time:** 189 ms - **AI review time:** 599195 ms - **Total time:** 600915 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:** The executable performs an automatic self-update check and can globally install another wrapper release. No confirmed credential theft, destructive action, or foreign agent-control-surface mutation was identified. - **Trigger:** Running the whalent executable or importing its main entrypoint. - **Impact:** A later package release selected by the updater can replace the global executable; opaque update logic makes that supply-chain behavior difficult to independently verify. - **Evidence paths:** dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T06:52:18.289Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The obfuscated entrypoint calls its update routine, selects a wrapper version, and invokes a global package installation through a child process. - **Rationale:** The package has no automatic npm install hook, so the evidence does not establish an install-time attack. Its opaque, automatic global self-update capability is nevertheless a meaningful supply-chain risk that warrants a warning. ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Package metadata exposes the bundled wrapper as both the main module and the whalent executable., The executable unconditionally invokes its wrapper update check before supervising the core runtime., The update path installs a selected version of the wrapper package globally through a child-process call., The distributed entry bundle is deliberately obfuscated, preventing transparent auditing of the update and execution path. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The update behavior is activated when the wrapper runs, rather than during npm installation. ## Affected versions and remediation This report applies to @whalent/agent@0.3.439. - Review the evidence and your use of @whalent/agent@0.3.439 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.
