Purpose

Scheduled Task Jobs are a way for adversaries to set up executable, or malicious code, to be run at different times. This technique can apply to all major operating systems because they all have the functionality to schedule these programs to run at a certain time and with certain prerequisites. Anytime an executable is run that is not transparent to the user can cause disruptions to the business.

These detections help your SOC understand what steps and events occurred before the program was run. Even better, it can help notify the SOC when an adversary has attempted some of these steps and can help provide real-time information for the SOC to thwart those attempts.

Security Operations application

SecOps users can obtain detailed information if they install these alerts using the Content Manager instead.

More information about MITRE framework

Adversaries may abuse task scheduling functionality to facilitate initial or recurring execution of malicious code. Utilities exist within all major operating systems to schedule programs or scripts to be executed at a specified date and time. A task can also be scheduled on a remote system, provided the proper authentication is met (for example RPC and file and printer sharing in Windows environments). Scheduling a task on a remote system typically may require being a member of an admin or otherwise privileged group on the remote system.

Prerequisites

To use this alert pack you must have the following data sources available in your domain:

Open alert pack

Once you have installed the alert pack, you can use the Open button at the top right of the card in Exchange to access the Alert configuration, where you can apply filters to find it and later manage it as required. You can also access this area via the Navigation pane (Administration → Alert Configuration → Available alerts).

Use alert pack

The alerts in the alert pack are deactivated by default when the alert pack is installed. Access the Alert configuration area to activate those you need and assign sending policies to receive them through the desired channels.
