This includes: Passive DNS Data : Historical records of DNS queries, enabling investigators to trace domains used in past attacks.
Infrastructure Intelligence Needs to be the First Step: Every attack, and every criminal, utilizes Internet infrastructure and other Internet resources (emails, phone numbers, DNS data, etc) to command and control their attacks; utilizing this knowledge as the first step provides the best path for rapid, efficient triage.
