## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 5 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 11.59.0
- **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 malware: the inspected package contains no payload execution, persistence, credential access, or destructive behavior. However, it performs automatic network telemetry at install time, so it warrants a non-blocking warning.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 86.0%
- **Started:** 2026-09-12T23:49:18.358Z
- **Finished:** 2026-09-12T23:50:00.588Z
- **Download time:** 753 ms
- **Static scan time:** 36 ms
- **AI review time:** 41440 ms
- **Total time:** 42230 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:** The postinstall hook invokes a telemetry client with a shipped configuration. The package does not contain the telemetry client's implementation, so its exact collected fields cannot be verified from this snapshot.

- **Trigger:** Installing the package with lifecycle scripts enabled.

- **Impact:** May transmit dependency-related installation metrics to IBM; no credential theft, destructive action, or remote code execution is established.

- **Evidence paths:** package.json, telemetry.yml

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T23:50:00.588Z

### AI review details

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

- **Mechanism:** Automatic telemetry submission during postinstall.

- **Rationale:** This is not malware: the inspected package contains no payload execution, persistence, credential access, or destructive behavior. However, it performs automatic network telemetry at install time, so it warrants a non-blocking warning.

- **Files touched:** telemetry.yml

- **Network endpoints:** https://www-api.ibm.com/ibm-telemetry/v1/metrics

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 86.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** Installation automatically runs an IBM telemetry command., Telemetry is configured to send metrics to an IBM endpoint and includes npm dependency collection settings.

- **Evidence against:** The shipped JavaScript entrypoints contain layout constants and unit-conversion helpers only., No package source invokes shells, evaluates code, harvests credentials, writes files, or loads remote payloads., There is no self-dependency or AI-agent control-surface behavior.
