Nokia Deepfield found more than 100% increase in daily DDoS peak traffic in this time period. DDoS threat potential over 10 Tbps four to five times higher than the largest current attacks reported due to rapidly growing number of open and insecure internet services and IoT devices. Most global DDoS attacks (by frequency and traffic volume) originate in less than 50 hosting companies and regional providers. Most of the high-bandwidth, high-intensity (volumetric) attacks are traced to a limited number of internet domains.”]
