The rule detects the execution of the Windows utility 'Ldifde.exe' when it is run with the import flag '-i'. This command can be exploited to download arbitrary files from remote servers, posing a significant security risk if an attacker utilizes this method to infiltrate or manipulate the system. The detection mechanism focuses on process creation events within the Windows operating environment, specifically looking for instances where 'Ldifde.exe' is called with specific command-line arguments indicative of an import operation. Given the potential misuse of this functionality, it is essential to monitor its usage to prevent unauthorized data import and malicious file downloads.
