| Rulename | M365D Alerts Correlation to non-Microsoft Network device network activity involved in successful sign-in Activity |
| Description | This content is employed to correlate with Microsoft Defender XDR phishing-related alerts. It focuses on instances where a user successfully connects to a phishing URL from a non-Microsoft network device and subsequently makes successful sign-in attempts from the phishing IP address. |
