Australian organisations are being hit by over 450 distributed denial of service (DDoS) attacks every day and fully a quarter of them are coming from domestic sources. Figures show DDoS attacks making a resurgence after nearly a year of decline. The largest of the attacks, in early August, measured 51.9 Gbps in intensity while the heaviest volume of packets 15.8 million packets per second came in an attack later in the month. The figures reinforce the resurgent threat from DDoS, which flood targets with data in an effort to interrupt their operation for even a short period.”]
