Description
This module will create a permanent WMI event subscription to achieve file-less persistence using an event filter that will query the event log for an EVENT_ID_TRIGGER (default: failed logon request id 4625) that also contains a specified USERNAME_TRIGGER (note: failed logon auditing must be enabled on the target for this method to work, this can be enabled using "auditpol.exe /set /subcategory:Logon /failure:Enable"). When these criteria are met a command line event consumer will trigger an encoded powershell payload.
Additionally a custom command can be specified to run once the trigger is activated using the advanced option CustomPsCommand. This module requires administrator level privileges as well as a high integrity process. It is also recommended to use staged payloads due to powershell script length limitations.
