Kinetik engine and project initializer for Three.js games

AI Security Review

scanned 3h ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. The package has a lifecycle hook that refreshes a package-aligned editor HTML file in a consuming project and runtime game networking/script-loading features that are user/application invoked.

Static reason
One or more suspicious static signals were detected.
Trigger
npm install for editor HTML sync; runtime calls for networking and script loading
Impact
May update src/editor.html during install when a consuming project has src/, but no evidence of credential theft, exfiltration, persistence, or agent hijack.
Mechanism
project scaffold/update plus browser game engine modules
Rationale
Source inspection shows suspicious primitives are package-aligned game engine behavior: scaffold file generation, an editor-template postinstall refresh, browser dynamic module loading for level scripts, and user-configured networking. No concrete malicious behavior, exfiltration, persistence, or AI-agent control hijack was found.

Decision evidence

public snapshot
AI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for block
  • package.json defines postinstall: node sync-generated-editor-html.js
  • sync-generated-editor-html.js can overwrite INIT_CWD/src/editor.html from scaffold template when src/ exists
  • scriptManager.js dynamically imports level/object script paths from gameState/userData at runtime
  • networking.js implements user-configured WebRTC signaling and STUN usage
Evidence against
  • No credential, env, home-directory, npmrc, SSH, or secret harvesting found by source search
  • No hardcoded exfiltration endpoint; networking apiBase is caller configured
  • No AI-agent control-surface writes, MCP/Claude/Codex/Cursor config mutation, persistence, or shell startup hooks found
  • bin/create-kinetik-app.js and init.js only scaffold package-aligned game project files
  • child_process usage is only in scaffold/scripts/run-electron.js to launch Electron for generated app
  • Dynamic imports are browser game scripts from level/editor metadata, not install-time remote code
