Change(s):
Analytic Rules/WhoisFreaks-HighConfidenceThreat.yaml: confidence filter changed fromtoint(confidence) >= 80 or confidence =~ "high"totodouble(confidence) >= 0.8; rule description now states the 0 to 1 confidence scale and the 0.8 threshold.Analytic Rules/WhoisFreaks-FreshNRD-Burst.yaml: fixed threshold of 5,000 distinct domains per hour replaced with a daily baseline comparison. The rule now runs daily over an 8-day window and alerts when the last 24 hours of distinct NRD domains is at least 50% above the average of the previous seven daily loads and more than three standard deviations from it. Requires at least three baseline days.Reason for Change(s):
confidenceas a decimal between 0 and 1 (for example1.0). The previous integer comparison never matched, so the high-confidence rule could never fire.Version Updated:
