What it detects

This rule detects creation of google_cache.db under a macOS temp directory such as private tmp, the collection store used by the BlueNoroff keylogger and screen capture module analyzed by Huntress. The implant records keystrokes and screenshots into this disguised database before exfiltration. A capture database with a browser-cache-like name in a temp path is a strong collection indicator.
