This is a Splunk application containing several dashboards and over 120 reports that will facilitate initial hunting indicators to investigate.
You obviously need to be ingesting Sysmon data into Splunk, a good configuration can be found here
Note: This application is not a magic bullet, it will require tuning and real investigative work to be truly effective in your environment. Try to become best friends with your system administrators. They will be able to explain a lot of the initially discovered indicators.
Big credit goes out to MITRE for creating the ATT&CK framework!
