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 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
Its licence does not clear it for publishing here
Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.
Detection requirements
- Platform
- Containers
The rule states no platform. This is derived from the ATT&CK technique it maps to.
- Log source category
- event_index
Known benign triggers
- There is a potential for false positives if the "jq" command is used for legitimate purposes, such as debugging or troubleshooting. It is important to investigate any alerts generated by this rule to determine if they are indicative of malicious activity or part of legitimate container activity.
