* [New] Multiple Alerts on a Host Exhibiting CPU Spike
This rule correlates multiple security alerts from a host exhibiting unusually high CPU utilization within a short time window. This behavior may indicate malicious activity such as malware execution, cryptomining, exploit payload execution, or abuse of system resources following initial compromise.

* [New] Detection Alert on a Process Exhibiting CPU Spike
This rule correlates security alerts with processes exhibiting unusually high CPU utilization on the same host and process ID within a short time window. This behavior may indicate malicious activity such as malware execution, cryptomining, exploit payload execution, or abuse of system resources following initial compromise.

* Added logic to main.py to use the created_at and updated_at values from the ndjson file if they exist.
* Add comment for parsing created_at and updated_at fields to metadata
* updated the date metadata code based on PR feedback
* Add --dates-import option to rule import command
Introduce a new option `--dates-import` to parse `created_at` and `updated_at` fields from rule content. This allows users to import date metadata while preventing conflicts with existing date options.
* Update version to 1.5.23 for release preparation
This update increments the version number in the project metadata
to reflect the upcoming release. No other changes were made.
* Update date metadata logic to include timezone information
Modified the handling of creation and updated dates to ensure
that the datetime objects are timezone-aware by replacing the
timezone info with UTC. This change improves the accuracy of
date metadata in the rules.
* Updated format of main.py using ruff
* Update project version to 1.5.29
* updating pyproject version

* [New] SOCKS Traffic from an Unusual Process
This detection correlates FortiGate's application control SOCKS events with Elastic Defend network event to identify the
source process performing SOCKS traffic. Adversaries may use a connection proxy to direct network traffic between systems
or act as an intermediary for network communications to a command and control server to avoid direct connections to their
infrastructure.
