Machine Learning Detected DGA activity using a known SUNBURST DNS domain

edit

A supervised machine learning model has identified a DNS question name that used by the SUNBURST malware and is predicted to be the result of a Domain Generation Algorithm.

Setup

edit

Setup

The rule requires the Domain Generation Algorithm (DGA) Detection integration assets to be installed, as well as DNS events collected by integrations such as Elastic Defend, Network Packet Capture, or Packetbeat.

DGA Detection Setup

The DGA Detection integration consists of an ML-based framework to detect DGA activity in DNS events.

Prerequisite Requirements:

Fleet is required for DGA Detection.
To configure Fleet Server refer to the documentation.
DNS events collected by the Elastic Defend, Network Packet Capture integration, or Packetbeat.
To install Elastic Defend, refer to the documentation.
To add the Network Packet Capture integration to an Elastic Agent policy, refer to this guide.
To set up and run Packetbeat, follow this guide.

The following steps should be executed to install assets associated with the DGA Detection integration:

Go to the Kibana homepage. Under Management, click Integrations.
In the query bar, search for Domain Generation Algorithm Detection and select the integration to see more details about it.
Follow the instructions under the Installation section.
For this rule to work, complete the instructions through Configure the ingest pipeline.
