Link11 has released data showing DDoS attacks were at their highest levels in November on two of the busiest online trading days of the year. On Black Friday, Link11’s Security Operations Centre saw DDoS attacks on e-commerce providers increase by over 70 percent compared with other days in November. On Cyber Monday, attacks increased by 109 percent compared with the November average.

Several attacks observed during Black Friday and Cyber Monday were of up to 100 Gbps bandwidth, and the average attack volume on both days was just under 6Gbps. In Q3 2018, the average attack volume observed by Link11 was 4.6 Gbps. According to Link11, attack volumes approaching 6Gbps far exceed the capacity of most websites. As such, Link11 is warning online merchants, payment providers and logistics companies to anticipate further large-scale DDoS attacks in the run-up to the Christmas break.

Marc Wilczek, Managing Director of Link11 says: "The e-commerce industry has high expectations of the Christmas trading period, and both criminals and competitors will take this as an opportunity to cause disruption to or extort the e-commerce industry. The growing ‘cybercrime-as-a-service’ sector favours this development. Online retailers should take action now to strengthen their IT security defences against DDoS attacks, in advance."
