The rule identifies the use of 'fsutil.exe' to delete the USN Journal volume in Windows systems. This technique is often employed by attackers to eliminate traces of actions taken during a breach, particularly in post-exploitation scenarios where the attacker seeks to cover their tracks. The USN Journal tracks changes to files and directories and is an important part of forensic analysis. By monitoring for the execution of 'fsutil.exe' with arguments specifying the deletion of the USN Journal, this rule enables detection of potential malicious activity that could lead to data compromise. Investigation should include analyzing the process execution chain, identifying user accounts involved, and reviewing logs for further suspicious activity.
