## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 19 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Staged Payload Carrier
- **Selected version:** 0.4.1
- **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.

The package is not shown to be malicious, but its automatic lifecycle delivery of executable native payloads is a concrete supply-chain risk. Hash pinning and temporary Codex-auth isolation reduce, but do not remove, that risk.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 83.0%
- **Started:** 2026-08-13T04:40:04.510Z
- **Finished:** 2026-08-13T04:42:02.896Z
- **Download time:** 504 ms
- **Static scan time:** 17422 ms
- **AI review time:** 100458 ms
- **Total time:** 118386 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:** Installation downloads two hashed native binaries into package-owned ~/.negotium state. Runtime can later execute bash-rs for background shell capability.

- **Trigger:** npm postinstall; later Negotium runtime use

- **Impact:** Automatic native payload installation expands supply-chain risk.

- **Evidence paths:** package.json, install-browser-rs.mjs, install-bash-rs.mjs, dist/runtime/src/platform/background-bash/manager.ts, dist/runtime/src/agents/codex-native-multi-agent.ts

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T04:42:02.896Z

### AI review details

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

- **Mechanism:** verified remote native-binary download and execution

- **Rationale:** The package is not shown to be malicious, but its automatic lifecycle delivery of executable native payloads is a concrete supply-chain risk. Hash pinning and temporary Codex-auth isolation reduce, but do not remove, that risk.

- **Files touched:** install-browser-rs.mjs, install-bash-rs.mjs, ~/.negotium/binaries/browser-rs/v0.1.21/browser-rs, ~/.negotium/binaries/bash-rs/v0.1.7/bash-rs

- **Network endpoints:** github.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 83.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** postinstall automatically runs two downloader scripts., Install scripts fetch platform-native executables from GitHub releases., Downloaded binaries are SHA-256 checked then stored executable under ~/.negotium and later used by runtime.

- **Evidence against:** No fixed unofficial credential gateway or exfiltration endpoint found., Codex auth is copied only into a temporary isolated home for cache generation, then removed., No install-time foreign AI-agent configuration mutation found.
