## Verdict summary
**Blocked & quarantined** — User-level AI-agent behavior and configuration can be changed without an explicit setup command; existing assets may be overwritten.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 0.9.0
- **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: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

Installing globally runs an opaque native executable and automatically changes global Claude Code and AI configuration. It can overwrite command assets and leave a global Stop hook affecting every Claude Code session.

## Security analysis

### Published attack-surface review

- **Summary:** Installing globally runs an opaque native executable and automatically changes global Claude Code and AI configuration. It can overwrite command assets and leave a global Stop hook affecting every Claude Code session.

- **Trigger:** npm global installation runs postinstall as a non-root user.

- **Impact:** User-level AI-agent behavior and configuration can be changed without an explicit setup command; existing assets may be overwritten.

- **Evidence paths:** package.json, scripts/postinstall.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-09-12T19:04:52.912Z

### AI review details

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

- **Mechanism:** Postinstall executes a bundled binary to synchronize global agent assets and hooks.

- **Attack narrative:** A global npm install invokes postinstall. That script executes the opaque bundled native binary for preflight and asset synchronization, which targets shared user agent directories. The package declares that it registers global Claude commands, overwrites existing copies, and installs a global Stop hook. This is an automatic mutation of a broad foreign AI-agent control surface rather than an explicit user-invoked setup step.

- **Rationale:** The automatic lifecycle hook executes an opaque binary that modifies shared AI-agent configuration and can overwrite user assets. This meets the install-hook abuse boundary even without evidence of network exfiltration.

- **Files touched:** scripts/postinstall.js, libexec/claudespace.dist/claudespace-bin, ~/.claude, ~/.claude/commands, ~/.ai/prompts, ~/.config/claudespace

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The package automatically runs a postinstall script., Postinstall invokes an opaque bundled native executable twice, including a sync-assets command., The automatic asset sync targets the user's global Claude and AI configuration directories., The package states that its global Claude commands overwrite existing user copies and that it installs a global Stop hook., Postinstall also removes an existing pipx installation without an explicit user command.

- **Evidence against:** No network endpoint or credential-exfiltration code was found in the readable JavaScript and shell sources., No runtime dependency on another release of this package is declared.

## Affected versions and remediation

This report applies to @ayorcodes/claudespace@0.9.0.

- Avoid installing @ayorcodes/claudespace@0.9.0. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.

L11: * `sudo npm i -g` those either resolve to `/var/root` (silently the wrong
