Scheduled Tasks

Theory

In Windows, the Task Scheduler service allows to run automated tasks on a chosen computer. The tasks are used to run programms when a specific trigger occurs. Triggers work like conditions, triggering the execution of one or more actions when they are met. For example, a trigger can be temporal, linked to a particular date, launched when the system starts up, when the user logs on or in response to a Windows event.

If its misconfigured, it can be an interesting vector for privilege escalation. At the enumeration stage we are interested into following Scheduled Tasks parameters:

  • The "Run As User" (i.e under which user the task will run)

  • The Trigger (i.e when the task will be run)

  • The task to be run (i.e what will be executed by this task)

Practice

To enumerate scheduled tasks, we may use following PowerShell commands.

Get-ScheduledTask
