Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.3.406 - **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. No automatic lifecycle hook or concrete theft, destructive action, or foreign control-surface mutation was found. The deliberately opaque executable runtime combined with agent, process, and code-execution capability warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-07T16:52:06.392Z - **Finished:** 2026-09-07T16:53:06.256Z - **Download time:** 1040 ms - **Static scan time:** 231 ms - **AI review time:** 58592 ms - **Total time:** 59864 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:** Running the whalent command launches an opaque agent runtime with local process and code-execution capability. No install-time attack surface was found. - **Trigger:** A user runs the whalent CLI or sends an execute request to its Jupyter sidecar. - **Impact:** A user who runs and connects the agent may expose local execution capability to its configured control plane; the obfuscation prevents verifying its safeguards. - **Evidence paths:** dist/index.cjs, dist/core.cjs, dist/jupyter\_sidecar.py - **Review source:** ai\_review - **Reviewed:** 2026-09-07T16:53:06.256Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Opaque agent runtime with child-process, remote-agent, and local kernel execution capability. - **Rationale:** No automatic lifecycle hook or concrete theft, destructive action, or foreign control-surface mutation was found. The deliberately opaque executable runtime combined with agent, process, and code-execution capability warrants a warning. - **Files touched:** dist/index.cjs, dist/core.cjs, dist/jupyter\_sidecar.py ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The CLI entry point and its 15 MB core runtime are heavily obfuscated, preventing meaningful auditing of its process-spawning, updater, and persistence paths., The included Jupyter sidecar accepts an execute request and starts a Python worker with supplied code., The package is an agent wrapper that ships a separate optional core runtime and declares SSH, WebSocket, proxy, and terminal dependencies. - **Evidence against:** The manifest has no preinstall, install, postinstall, or prepare hook; installation alone does not run the executable., The visible Python sidecar is a bounded local NDJSON kernel bridge and contains no outbound-network code. ## Affected versions and remediation This report applies to @whalent/agent@0.3.406. - Review the evidence and your use of @whalent/agent@0.3.406 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.
