| Rulename | [Deprecated] - Known Diamond Sleet related maldoc hash |
| Description | This query has been deprecated as the associated IoCs (Indicators of Compromise) are outdated and no longer relevant. To ensure effective threat detection, it is recommended to implement Microsoft’s Threat Intelligence solution, which enables matching your log data with the most up-to-date IoCs generated by Microsoft. This solution can be installed from the Microsoft Sentinel Content Hub if not currently deployed.
