Summary
The analytic rule titled 'Monitor Registry Keys for Print Monitors' is designed to detect modifications to a critical Windows registry key related to print monitoring. Specifically, it focuses on the registry path `HKLM\SYSTEM\CurrentControlSet\Control\Print\Monitors`. The rule captures events using the Sysmon data source, specifically EventID 12 and EventID 13, which log registry modifications. This threat detection strategy is particularly important because attackers can manipulate this registry key to introduce malicious .dll files, which can execute with elevated SYSTEM privileges. Such actions may lead to advanced persistence mechanisms, allowing attackers to maintain control over the system and execute harmful operations, including deploying further exploits or software. By implementing this detection, security teams can respond to potential registry abuse quickly, potentially mitigating significant security risks associated with unauthorized program execution and persistence on Windows systems.
