Question

An analyst receives a threat intelligence report describing a new APT group using a specific YARA signature pattern in their custom implant. The organization has a SIEM with endpoint telemetry. Which action most effectively operationalizes this intelligence?

Accepted Answer

Deploy the YARA rule to the EDR and SIEM for retrospective hunting across historical endpoint telemetry and configure a real-time alert for future matches — Here's the deal — b is correct because operationalizing threat intelligence means converting indicators (YARA signatures) into active detections; retrospective hunting may reveal past compromise, and real-time alerting catches future activity. A is wrong because filing without action wastes actionable intelligence.

Answer
