Using machine learning to detect DGA with >99.9% accuracy

Supporting material for ElasticON 2020 talk on detecting DGA activity.

Note, full model, configuration and details on how to deploy the model will shortly be available in https://github.com/elastic/detection-rules

dga_ElasticON_2020.ipynb shows how the model was trained.

Supporting data files are available https://storage.googleapis.com/elastic-ml-public/elasticon_2020_dga/dga_ElasticON_2020.tar

CPU: percentage of limit

A lot of people land when trying to find out how to calculate CPU usage metric correctly in prometheus, myself included! So I'll post what I eventually ended up using as I think it's still a little difficult trying to tie together all the snippets of info here and elsewhere.

This is specific to k8s and containers that have CPU limits set.

To show CPU usage as a percentage of the limit given to the container, this is the Prometheus query we used to create nice graphs in Grafana:

sum(rate(container_cpu_usage_seconds_total{name!~".*prometheus.*", image!="", container_name!="POD"}[5m])) by (pod_name, container_name) /

Ansible variable precedence

Source: http://docs.ansible.com/ansible/latest/playbooks_variables.html#variable-precedence-where-should-i-put-a-variable

From least to most important

• command line values (for example, -u my_user, these are not variables)
• role defaults (defined in role/defaults/main.yml)
• inventory file or script group vars
• inventory group_vars/all

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1
