What it detects

This rule detects csvde.exe exporting directory data to a file, a bulk LDAP account-enumeration technique observed following MSIX malware delivery by Red Canary. Adversaries use csvde to dump the entire directory for reconnaissance and targeting, so its use outside routine administration warrants review.
