brainstorming

No explicit signs of stealth, process execution, reverse shells, or network exfiltration are evident in this module alone. However, the code creates a high-impact client-side execution surface: it directly serves HTML originating from a watched directory (defaulting to /tmp/brainstorm) and injects helper.js verbatim into an inline <script> tag. If attackers can influence SCREEN_DIR contents or helper.js in the runtime supply chain/build, they can execute arbitrary JavaScript in clients’ browsers. Separately, the unauthenticated WebSocket JSON parsing lacks error handling (availability risk) and can persist client-supplied data to disk (.events), increasing local data retention risk.
