Create IOCs on Malicious Files from a CrowdStrike Detection - Workflow Template

For each new EDR detection, validate the files involved with threat intelligence, add to global block list if found to be malicious

Updated over 7 months ago

This workflow template automates the process of handling new Endpoint Detection and Response (EDR) detections from CrowdStrike. Upon receiving an event, it decodes the detection ID, retrieves detailed information, and checks each related file's SHA256 signature against VirusTotal's threat intelligence. Files confirmed as malicious are automatically added to a global block list, enhancing an organization's defense by preventing the execution or access of such files across their platform. This streamlines the process of managing and neutralizing threats identified by CrowdStrike.
