Isai ed42a9e9dd [Rule Tuning] AWS CLI with Kali Linux Fingerprint Identified (#5467)
* [Rule Tuning] AWS CLI with Kali Linux Fingerprint Identified

This rule is performing well in telemetry as expected. I changed this to EQL to avoid the multiple wildcards needed with KQL.

- changed rule type to EQL
- reduced execution window
- updated description, false positive and investigation guide

Script for testing this rule:
Manually perform any action against our AWS account using Kali Linux distribution

#### Screenshot showing working EQL query, still captures the BitPanda behavior this rule was initially designed around.

* add highlighted fields

add highlighted fields

* Update initial_access_kali_user_agent_detected_with_aws_cli.toml

Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
