The rule 'Werfault ReflectDebugger Persistence' is crafted to detect changes in registry keys associated with the Windows Error Reporting service, specifically designed to identify malicious activity that may exploit the 'ReflectDebugger' setting. This detection rule targets scenarios where an attacker manipulates the Werfault utility to execute harmful payloads whenever the utility is invoked with the '-pr' parameter. The EQL query looks for modifications in certain registry paths relevant to the ReflectDebugger in a Windows environment. Given that attackers may utilize this method for persistence, the rule not only monitors for unauthorized changes but also provides steps for investigation and remediation in case of alerts. The primary focus of the rule is to enhance security by alerting administrators about potentially exploitative modifications while also offering insights into investigative measures that can help in understanding the context of suspicious changes.
