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:** 2026-09-01T16:16:28.736Z - **Finished:** 2026-09-01T16:18:23.454Z - **Download time:** 506 ms - **Static scan time:** 2668 ms - **AI review time:** 111543 ms - **Total time:** 114718 ms ## Security analysis ### Published attack-surface review - **Summary:** This is a high-privilege AI-agent application that can run shell commands and modify files. Its optional components can download and execute external software after a user action. - **Trigger:** A user or connected agent interaction invokes command, file, Python, skill-install, or Obscura-install functionality. - **Impact:** A prompt injection or unauthorized connected-agent request could lead to arbitrary local commands, file changes, or execution of downloaded software. - **Evidence paths:** src/agent/tools.js, src/main.js, src/agent/obscura.js, src/agent/store.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T16:18:23.454Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** AI-directed shell execution, file writes, and unsigned component installation. - **Rationale:** The code presents substantial agent-control and downloaded-executable risk, but the dangerous operations are application features rather than a confirmed covert install-time attack. Classify as a warning for dangerous capability exposure. - **Files touched:** %APPDATA%\\beast\\skills\\\, %APPDATA%\\beast\\py, %APPDATA%\\beast\\obscura - **Network endpoints:** github.com, raw.githubusercontent.com, www.python.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The agent exposes unrestricted PowerShell command execution., Risky agent tools are disabled only by an optional approval setting, which defaults off., A user-invoked installer downloads, extracts, and runs an unsigned external browser executable., The skill store writes remotely supplied skill files into the application's skill directory. - **Evidence against:** The external browser installer is reached through an explicit application IPC action, not automatically at npm install., No credential harvesting, secret exfiltration, or covert install-time payload execution was confirmed., The declared postinstall script points to a file absent from this package snapshot, so it cannot establish install-time behavior here. ## Public findings ### 1.
