Potential Cluster Enumeration via jq Detected via Defend for Containers

  • T1613

Description

This rule detects the enumeration of the cluster by the “jq” command inside a container. The “jq” command is used to parse JSON data, and may be used by an adversary to gain information about the cluster and the services running inside it. This behavior is uncommon for interactive shells within a container, and is commonly leveraged by attackers to help parse cluster information in a more readable format, or set the output as environment variables.

Detection logic

process where host.os.type == "linux" and event.type == "start" and event.action == "exec" and process.name == "jq" and
process.interactive == true and container.id like "?*"
