Fsutil Suspicious Invocation for Defense Evasion or Data Destruction
This rule detects suspicious invocations of the `fsutil.exe` utility, specifically when it's used to delete the USN journal, create a USN journal with a small size, or set zero data to a file. These actions are often associated with ransomware or other malicious activity aimed at defense evasion and data destruction, as seen in campaigns like NotPetya and Lockbit.
