Pure flour-power. Hearty enough to carry you through lunch.
Summary
This blog post by "souzo" introduces clickdetect, a repository/tool designed to extend Wazuh's detection capabilities by integrating with OpenSearch PPL (Piped Processing Language) and Sigma Rules. The author discusses frustrations with OpenSearch's detection engine being buggy and prone to index corruption, and presents clickdetect as a solution for creating alerting rules that work reliably in Wazuh without fighting the detection engine.
Key quotes
