Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Unknown - **Selected version:** 0.3.488 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. Source inspection supports a warning for unresolved executable behavior in heavily obfuscated bundles, with the main entrypoint exceeding the inspection tool's size limit. The inspected functionality and manifest do not establish a block-eligible attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 70.0% - **Started:** 2026-10-02T22:41:57.574Z - **Finished:** 2026-10-02T22:42:55.944Z - **Download time:** 1284 ms - **Static scan time:** 1505 ms - **AI review time:** 55580 ms - **Total time:** 58370 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:** Obfuscated runtime execution remains unresolved. Inspection did not establish exfiltration, malicious installation behavior, or another confirmed attack. - **Trigger:** Launching the CLI or loading its runtime entrypoint. - **Impact:** Potential runtime effects remain uncertain; no concrete malicious impact was demonstrated. - **Evidence paths:** dist/index.cjs, dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-02T22:42:55.944Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Encoded string lookup and obscured process calls prevent confidently tracing the executable bundle's behavior. - **Rationale:** Source inspection supports a warning for unresolved executable behavior in heavily obfuscated bundles, with the main entrypoint exceeding the inspection tool's size limit. The inspected functionality and manifest do not establish a block-eligible attack. ### Review decision - **Verdict:** Suspicious - **Confidence:** 70.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for warning:** The executable bundles obscure identifiers and strings, leaving runtime behavior unresolved after bounded inspection., dist/index.cjs contains obfuscated child-process calls; its size exceeds the source tool's inspection and citation verification limit. - **Evidence against:** package.json has no lifecycle scripts or runtime self-dependency., The inspected dynamic function construction belongs to bundled schema compilation, not a demonstrated hidden payload loader., The MCP startup accepts command-line configuration and a token; no covert credential export was established. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.488. - Review the evidence and your use of @whalent/agent-core@0.3.488 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.
