Research direction
Review the false-positive details for the NtOpenFile access to the Windows WinSxS security-vaultcmd path, then inspect the associated capa rule and the linked CAPE report. Done means the rule no longer incorrectly identifies this legitimate Windows credential-manager behavior while still matching its intended capability.
