## Security analysis

### Published attack-surface review

- **Summary:** The launched Electron agent can execute arbitrary PowerShell and Python commands selected by an LLM. It also persists itself at user login after runtime launch.

- **Trigger:** A user launches the global CLI/app and submits work that causes the model to call command or Python tools.

- **Impact:** A prompt-injected or otherwise compromised model session could run commands with the user's privileges and persist the app at login.

- **Evidence paths:** src/agent/tools.js, src/main.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-31T17:25:22.807Z

### AI review details

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

- **Mechanism:** LLM-directed shell execution, automatic runtime download, and login-startup registration.

- **Rationale:** This is a dangerous desktop-agent capability with runtime persistence, so it warrants a warning. Static inspection did not establish malicious install-time behavior or concrete exfiltration.

- **Files touched:** %APPDATA%\\beast\\py, %TEMP%\\beast-py-embed.zip, src/agent/tools.js, src/main.js

- **Network endpoints:** https://www.python.org/ftp/python/3.12.8/python-3.12.8-embed-amd64.zip

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for:** The agent exposes arbitrary PowerShell command execution to its model tool layer., A Python runtime is downloaded from python.org, extracted, and then used to execute agent-supplied Python., When launched from a global npm installation, the app enables login startup and creates a desktop shortcut.

- **Evidence against:** The manifest has no install, preinstall, or postinstall hook; its only lifecycle hook is prepublishOnly., The runtime download URL is a fixed python.org release URL, not an opaque attacker-controlled endpoint., No self-dependency, credential exfiltration path, or hidden install-time execution was found.
