Malware Investigation & Response Incident Handler
This playbook is triggered by a malware incident from an endpoint integration. It performs enrichment, detonation, and hunting within the organization, and remediation on the malware. The playbook also covers the SIEM ingestion flow in which the fetching integration is the SIEM and EDR integrations grab all additional data. Currently supported EDR integrations are XDR, CrowdStrike Falcon, and Microsoft Defender for Endpoint. Currently supported SIEM integrations are QRadar and Splunk.
