## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 19 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 1.6.6
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection shows package-aligned WhatsApp media, networking, and optional VoIP functionality rather than a concrete attack chain. The lifecycle scripts are transparent and non-mutating.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 95.0%
- **Started:** 2026-08-30T01:19:03.747Z

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:** No confirmed malicious attack surface was established. Installation only performs a local runtime-version check and prints a banner.

- **Trigger:** Package installation runs the declared lifecycle scripts; VoIP and network helpers require explicit runtime use.

- **Impact:** No unconsented file mutation, credential collection, persistence, or exfiltration was found.

- **Evidence paths:** package.json, engine-requirements.js, postinstall-banner.js, lib/Utils/generics.js, lib/Utils/messages-media.js, lib/VoIP/wasm-engine.js, lib/VoIP/worker-bootstrap.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-30T01:20:40.363Z

### AI review details

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

- **Mechanism:** Local compatibility check, banner output, and user-invoked WhatsApp client functionality.

- **Rationale:** Source inspection shows package-aligned WhatsApp media, networking, and optional VoIP functionality rather than a concrete attack chain. The lifecycle scripts are transparent and non-mutating.

- **Files touched:** engine-requirements.js, postinstall-banner.js, package.json

### Review decision

- **Verdict:** Clean

- **Confidence:** 95.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** Install hooks only check the local Node version and print a banner., The optional VoIP runtime evaluates bundled local WASM support code when the VoIP client is initialized., Version helpers make explicit runtime requests to the package repository and WhatsApp.

- **Evidence against:** No install hook writes files, invokes a shell command, or contacts a network endpoint., No self-dependency or nested lifecycle dependency is declared., No credential harvesting, AI-agent configuration mutation, persistence, or destructive project mutation was found., The flagged child-process use is constrained ffmpeg media processing with argument arrays.
