## 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:** Remote Code Execution
- **Selected version:** 1.3.3
- **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 exposes concrete remote command execution and credential-upload capabilities, creating meaningful abuse risk. The install hook is transparent package-local archive extraction, and the credential flow is explicitly user-invoked, so static source does not establish malicious install-time behavior.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-09-12T17:47:14.816Z

- **Static scan time:** 4426 ms

- **Total time:** 82293 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:** A started Thalamus session maintains a remote RPC channel that can execute shell commands in its current project directory. An explicit credential-connect command also uploads Anthropic authentication material to the service.

- **Trigger:** Running a Thalamus session connected to its service, or explicitly running thalamus connect claude.

- **Impact:** A compromised or abusive service account could run commands within the active project session; users who invoke credential connection disclose tokens to the service.

- **Evidence paths:** dist/types-BwfyJoJS.cjs, dist/index.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T17:48:37.109Z

### AI review details

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

- **Mechanism:** Remote RPC shell execution and user-invoked vendor-token upload.

- **Rationale:** The package exposes concrete remote command execution and credential-upload capabilities, creating meaningful abuse risk. The install hook is transparent package-local archive extraction, and the credential flow is explicitly user-invoked, so static source does not establish malicious install-time behavior.

- **Files touched:** process.cwd()

- **Network endpoints:** https://thalamus.etai.app

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** A runtime WebSocket session registers RPC handlers and accepts remote RPC requests from the configured service., The remote "bash" handler passes a received command string to a shell executor in the active session directory., The explicit connect command obtains Anthropic authentication tokens and sends them to the Thalamus service.

- **Evidence against:** The postinstall hook only unpacks bundled tools under the package's own tools directory., Token registration is reached through the explicit "thalamus connect claude" command, not during installation., The shell handler restricts its working directory to the session directory and caps execution time.

## Affected versions and remediation

This report applies to thalamus@1.3.3.

- Review the evidence and your use of thalamus@1.3.3 before allowing it. Restrict the permissions described in this report.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
