This analytic rule detects attempts by processes to duplicate handles that target the winlogon.exe executable, which is a critical component of Windows operating systems. Utilizing Sysmon Event ID 10, the rule specifically identifies processes that engage with winlogon.exe while attempting to obtain particular access rights (0x1040). Such interactions are noteworthy as they may indicate malicious actors attempting to escalate privileges by leveraging the elevated security tokens typically associated with winlogon.exe. If the detection indicates confirmed malicious intent, it could signify that an attacker has gained elevated system privileges, posing a grave risk of full system compromise and potential unauthorized access to sensitive information. This rule serves as a proactive measure to monitor and mitigate potential threats emanating from privileged access abuse, aligning with broader cybersecurity defense strategies.
