Figure 52 covers just how much DDoS is getting blocked at various places, from Internet Service Providers (ISPs) at the start of the trip, to Autonomous System Numbers (ASNs) in the middle, to Content Delivery Networks New zero-day attack vectors that we observed and defended against: In January, Microsoft Windows servers with Remote Desktop Protocol (RDP) enabled on UDP/3389 were being abused to launch UDP amplification attacks. However, in the majority of cases it's possible to defend against DDoS attacks by implementing the industry's best current practices to maintain availability of services in the face of an incident. In June, we saw a huge uptick in SYN, SYN-ACK, and ACK flood attacks in the region and we mitigated multiple VIPs totaling up to 225M PPS of traffic. For example, a UDP-based amplification attack sends UDP packets to another server, such as a DNS (Domain Name System) or NTP (Network Time Protocol) server, with a spoofed sender IP address.
