## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 17 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:** 0.3.77
- **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 confirms automatic, opt-out-free installation telemetry linked to a persistent device identifier. The destination is package-aligned and the observed installation event contains environment metadata, so this supports a warning for privacy exposure rather than a malicious verdict.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious

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:** Installation automatically reports identifying installation metadata to the package’s telemetry service. This creates a privacy risk, but the inspected source does not establish a concrete attack.

- **Trigger:** Package installation runs the postinstall hook.

- **Impact:** The publisher can associate installation and environment metadata with a persistent device identifier.

- **Evidence paths:** package.json, bin/install.mjs, lib/telemetry/client/index.js, lib/telemetry/client/identity.js, lib/telemetry/client/environment.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-29T03:49:55.421Z

### AI review details

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

- **Mechanism:** The installer emits an installation event containing environment details; telemetry adds persistent device and session identifiers and posts queued events to its configured destination.

- **Rationale:** Source inspection confirms automatic, opt-out-free installation telemetry linked to a persistent device identifier. The destination is package-aligned and the observed installation event contains environment metadata, so this supports a warning for privacy exposure rather than a malicious verdict.

- **Files touched:** package.json, bin/install.mjs, lib/telemetry/client/index.js, lib/telemetry/client/identity.js, lib/telemetry/client/environment.js

- **Network endpoints:** https://telemetry.portomatic.com/v1/events

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 83.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** The postinstall hook automatically runs an installer that sends installation metadata without an affirmative opt-in., The telemetry payload includes a persistent device ID and session ID; the installer also supplies operating system, architecture, Node version, CI status, and package manager., The default recipient is the package’s Portomatic telemetry service. The inspected install flow does not include credentials or project content.

- **Evidence against:** The destination is package-aligned telemetry, and the installer describes its reporting as best effort., The inspected installer reports environment and installation metadata, not saved credentials or project files.
