dfirtrack VS sigma

DFIRTrack - https://github.com/dfirtrack/dfirtrack IR tracking application

Sigma rules https://github.com/SigmaHQ/sigma its value, I get it. Here’s a post https://www.linkedin.com/posts/nasreddinebencherchali_detection-blueteam-sigma-activity-7104868070069817344-mn91?utm_source=share&utm_medium=member_desktop detailing that 31 Sigma rules from the Sigma repository are triggering on different stages of the attack as described here https://thedfirreport.com/2023/08/28/html-smuggling-leads-to-domain-wide-ransomware/

Idea: A free and open-source web repository of Sigma detections where users can find, contribute, and suggest edits to detections. All user contributions will go through a StackExchange-style moderation queue. Built-in conversion from Sigma to the query language of your choice.

If you want more ideas/inspiration, or even just a starting point for baseline rule logic check out https://github.com/SigmaHQ/sigma https://github.com/SigmaHQ/sigma and look into the different rules folders there.

Agreed in general. But with stuff like SIGMA, I'd lean towards stuff should going into git. Better version control, your docs can be markdown and live right next to your threat library, you can strap on CI/CD (so you can deploy/run stuff as part of a pipeline). Confluence is a great start, but it doesn't scale well.

I created a Defender Advanced Hunting query based of the Sigma rule https://github.com/SigmaHQ/sigma/blob/master/rules/windows/process_creation/proc_creation_win_rundll32_webdav_client_susp_execution.yml
