According to Q1 2020 Threat Report published by the Nexusguard, DDoS attacks rose more than 278% compared to Q1 2019 and more than 542% compared to the last quarter. ISPs are facing increasing challenges to curb undetectable and abnormal traffic before they turn into uncontrollable reflection attacks.
