Summary
This detection rule identifies instances where a DHCP server fails to load a specified Callout Dynamic Link Library (DLL). The issue is primarily linked to errors occurring during the execution of the DHCP server service in Windows. Specifically, the rule monitors for specific Event IDs (1031, 1032, and 1034) that are logged when there is an error in the DHCP server's operation, particularly concerning Callout DLLs. These events indicate that the DHCP server service is unable to initialize or utilize certain components that might often be exploited for defense evasion techniques. The detection is implemented by correlating the events from the DHCP server and identifying potential anomalies that could signify an attempted manipulation of the DHCP configuration or an exploit attempt related to DLL injection, which falls under the techniques classified in attack frameworks. The high severity of the detection emphasizes the potential risks associated with these errors, including unauthorized access or service disruption.
