## Security analysis

### Published attack-surface review

- **Summary:** A global npm install automatically installs a remote Codex build and registers a GitHub Codex plugin. At runtime, relay messages can resume a local agent, with an automatic retry that disables Codex approval and sandbox protections.

- **Trigger:** npm install -g activates the postinstall hook; incoming relay messages activate agent resumption.

- **Impact:** It changes a broad AI-agent control surface and can cause network-delivered messages to run through a local agent with protections bypassed.

- **Evidence paths:** package.json, scripts/postinstall-global.mjs, dist/services/auto-relay.js, dist/services/codex-cli.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-31T17:06:13.924Z

### AI review details

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

- **Mechanism:** Install-hook mutation of Codex plus relay-driven unsandboxed agent execution.

- **Attack narrative:** The package's automatic postinstall hook runs during global installation, downloads and executes a remote installer, and registers an external marketplace and plugin in Codex. The package also turns relay messages into local agent resume commands and retries failed jobs with Codex approvals and sandboxing disabled. This creates an unconsented persistent expansion of the user's AI-agent execution surface.

- **Rationale:** This is concrete install-hook abuse: an npm postinstall mutates the foreign Codex control surface and executes remote shell content. The relay-driven bypass retry materially increases the resulting execution risk.

- **Files touched:** scripts/postinstall-global.mjs, ~/.codex/packages/standalone

- **Network endpoints:** https://chatgpt.com/codex/install.sh, https://github.com/eaisdevelopment/cogent.git

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** The manifest runs a postinstall script automatically., On global installation, the script pipes a remote Codex installer directly into sh., The postinstall adds a GitHub marketplace and installs a Codex plugin without an interactive consent step., Received relay messages are used to start local Codex or Claude resume commands., A failed sandbox can cause a retry with Codex approvals and sandboxing bypassed.

- **Evidence against:** The installer is guarded to run only for global npm installs and skips CI, Windows, and dependency installs., No direct credential harvesting or secret exfiltration was found in the inspected install hook.
