What it detects

This rule detects a process running from the OneNote exported attachment or temp directory loading the VBE7.dll VBA runtime, indicating macro or script execution from a weaponised OneNote embedded file. Legitimate applications rarely execute from the OneNote Exported path, so loading the VBA engine from there signals malicious code launched via a OneNote phishing lure.
