UAC Bypass Using EventVwr

Sigma Rules

View Source
Summary
This detection rule identifies the use of Windows Event Viewer as a method to bypass User Account Control (UAC). UAC is a security feature in Windows designed to prevent unauthorized changes to the operating system, and attackers often seek to bypass it to gain higher privileges. The rule monitors for the creation of files that match specific patterns associated with Event Viewer and checks if the originating process is from a legitimate Windows directory, filtering out normal operations from potential malicious activity. By specifically looking for files like 'RecentViews' within the Event Viewer directories and ensuring they originate from trusted locations, the detection logic delineates between standard and suspicious behavior, thus flagging potential privilege escalation attempts.
