## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 12 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:** 0.3.421
- **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.

This is not proven malware, but the obfuscated executable runtime and code-execution capability leave a material unresolved risk. The absence of install hooks and a concrete attack chain supports warning rather than blocking publication.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 82.0%
- **Started:** 2026-09-12T17:00:58.391Z

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 user-invoked CLI contains heavily obfuscated runtime code. A bundled sidecar can execute code supplied through its local protocol in a Jupyter kernel; no unconsented install-time attack was confirmed.

- **Trigger:** A user runs the whalent CLI or sends an execute request to the Jupyter sidecar.

- **Impact:** The opaque runtime and code-execution interface warrant caution, but static inspection found no confirmed exfiltration or install-time compromise.

- **Evidence paths:** dist/index.cjs, dist/core.cjs, dist/jupyter\_sidecar.py

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T17:02:02.640Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Opaque agent runtime with local Jupyter code execution capability.

- **Rationale:** This is not proven malware, but the obfuscated executable runtime and code-execution capability leave a material unresolved risk. The absence of install hooks and a concrete attack chain supports warning rather than blocking publication.

- **Files touched:** dist/index.cjs, dist/jupyter\_sidecar.py

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 82.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The published CLI is deliberately obfuscated; its build configuration includes an unobfuscated fast mode and a JavaScript obfuscator., The package exposes an executable entry point whose opaque bundled runtime cannot be meaningfully audited., Its Jupyter sidecar accepts supplied code and forwards it to a kernel for execution.

- **Evidence against:** The manifest has no preinstall, install, or postinstall lifecycle hook; prepublishOnly is not run when consumers install the package., It does not declare a runtime dependency on its own package name., No concrete credential theft, destructive action, or hard-coded network endpoint was established from the inspected files.

## Affected versions and remediation
