Exposed Docker APIs continue to be used by attackers to create new containers that perform cryptojacking.

Earlier this year we reported on attackers utilizing insecure Docker and Kubernetes systems to deploy containers that were used to mine coins. For those who are not familiar with containers, they are packages that contain an application and all the dependencies that are required to run it. These packages can then be deployed as containers to Docker or Kubernetes systems as needed.
