Advisory PublishedCVSS 5.4/10

Vulnetix · Advisory published April 1, 2026

Installs a macOS LaunchAgent (com.advanced-feature-juggler.daemon) via postinstall that persists across reboots and causes the computer to whisper random messages ('I can see your screen', 'Behind you') through the macOS say command every 15-60 seconds. Completely unrelated to its stated description of 'feature flag management utilities'. install.js writes a plist to ~/Library/LaunchAgents/com.advanced-feature-juggler.daemon.plist with RunAtLoad=true and KeepAlive=true, then calls launchctl load. The LaunchAgent continuously runs whisper.js which calls execSync('say -v Whisper -r 130 "<message>"') on a random 15-60 second timer. No network activity or data exfiltration observed.
