-description: The following analytic identifies a process that loads the credui.dll module. 
-  This legitimate module is typically abused by adversaries, threat actors and red teamers to create a credential UI prompt 
-  dialog box to lure users for possible credential theft or can be used to dump the credentials of a targeted host. 
-  This hunting query is a good pivot to check why the process loaded this dll and if it is a legitimate file. 
-  This hunting query may hit false positive for a third party application that uses a credential login UI for user login.
-search: '`sysmon` EventCode=7  (ImageLoaded = "*\\credui.dll" AND OriginalFileName = "credui.dll") OR (ImageLoaded = "*\\wincredui.dll" AND OriginalFileName = "wincredui.dll")
-  AND NOT(Image IN("*\\windows\\explorer.exe", "*\\windows\\system32\\*", "*\\windows\\sysWow64\\*", "*:\\program files*"))
-  | stats count min(_time) as firstTime max(_time) as lastTime by Image ImageLoaded OriginalFileName Computer EventCode Signed ProcessId ProcessGuid
-  | `security_content_ctime(firstTime)` 
-  | `security_content_ctime(lastTime)`
-  | `windows_input_capture_using_credential_ui_dll_filter`'
-how_to_implement: The latest Sysmon TA 3.0 https://splunkbase.splunk.com/app/5709 will 
-  add the ImageLoaded name to the process_name field, allowing this query to work. Use as an example and implement for other products.
-known_false_positives: this module can be loaded by a third party application. Filter is needed.
