Detection Metadata Validation:

Yes, like @ljstella mentioned - we are working on getting tooling and git actions a bit straightened out. We will keep you updated! and thank you contributing to security_content! |
Hello @zake1god : thank you for your patience! We have recently updated our tooling and have some general feedback about the detection. I will leave some inline comments on how we can improve this before we ship this detection. |

@zake1god : Do you have raw events that we can use in to test this detection against? :
Can you perhaps upload that data to - https://github.com/splunk/attack_data repo. You can use this directory for hosting your data : https://github.com/splunk/attack_data/tree/master/datasets/suspicious_behaviour
Fix name, Fix data_sources, Change type, Add drilldown_searches, Add analytic_story
Hello @zake1god : based on this CI failure: https://github.com/splunk/security_content/actions/runs/11487045805/job/31970703528?pr=3160 You likely need to update the file name to match the detection name |

nomenclatureNotes For Submitters and Reviewers
build
CI job when it fails will likely show an error about what is failing. You may have a very descriptive error of the specific field(s) in the specific file(s) that is causing an issue. In some cases, it's also possible there is an issue with the YAML. Many of these can be caught with the pre-commit hooks if you set them up. These errors will be less descriptive as to what exactly is wrong but will give you a column and row position in a specific file where the YAML processing breaks. If you're having trouble with this, feel free to add a comment to your PR tagging one of the maintainers, and we'll be happy to help troubleshoot it.
