iTWire Radware DDoS attack report shows dramatic rise in volumes Shares While DDoS attack numbers held fairly steady from the previous quarter of 2021, attack volumes escalated dramatically, a report from Radware has disclosed. Radware's recently released quarterly DDoS attack report analyses attack activity by industries, attack vectors, DDoS attacks on applications and on-premise versus cloud. Major findings include the following: The first half of Q1 was characterised by large attacks on finance and a continuation of the 2020 ransom DDoS campaign.
