This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-09-01T09:50:19.438Z - **Finished:** 2026-09-01T09:51:45.652Z - **Download time:** 504 ms - **Static scan time:** 2689 ms - **AI review time:** 83020 ms - **Total time:** 86214 ms ## Security analysis ### Published attack-surface review - **Summary:** This is a locally operated AI agent with shell, file-write, Python, messaging, and remote-skill capabilities. Its default configuration leaves approval disabled, so a configured and permitted agent session can perform these actions without a per-action confirmation. - **Trigger:** A user configures the application and submits a task through its desktop or permitted messaging interface; package installation also runs the Electron repair hook. - **Impact:** A prompt, compromised model response, or permitted remote message could cause arbitrary commands and file changes under the application's user permissions. - **Evidence paths:** package.json, scripts/fix-electron.js, src/main.js, src/agent/tools.js, src/agent/store.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T09:51:45.652Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** LLM-directed PowerShell and downloaded-runtime execution with remote skill installation. - **Rationale:** The package is not conclusively malicious, but it ships a high-impact AI-agent execution surface with approvals off by default and automatic executable downloads. Its postinstall behavior is limited to Electron repair rather than a foreign or broad agent-control-surface mutation. - **Files touched:** scripts/fix-electron.js, node\_modules/electron/dist, node\_modules/electron/path.txt, %APPDATA%\\beast\\py, %TEMP%\\beast-py-embed.zip, %APPDATA%\\beast\\skills - **Network endpoints:** https://www.python.org/ftp/python/3.12.8/python-3.12.8-embed-amd64.zip, https://npmmirror.com/mirrors/electron/, https://raw.githubusercontent.com/algokodcom/beast-agent/main/store/skills.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The install hook invokes a repair script that can remove Electron files and run Electron's installer., The repair script retries a binary download through a mirror and executes the dependency installer., The agent exposes unrestricted PowerShell command execution and the approval gate is disabled by default., On first Python use, it downloads an embedded runtime and extracts it before executing Python., The skill store fetches remote skill content and writes it into the application's skill directory. - **Evidence against:** No runtime dependency on beast-agent itself is declared., The install hook targets the bundled Electron dependency, not a foreign AI-agent configuration surface., The Python download and command tools are application capabilities rather than hidden import-time behavior., HTTP fetches reject local and private-network hosts., Messaging inputs are gated by configured allow lists; an empty list permits nobody. ## Public findings ### 1.
