Welcome to Cloudflare’s quarterly distributed denial-of-service (DDoS) report for the fourth and final quarter of 2022. This report uncovers insights and trends about the DDoS threat landscape observed across Cloudflare’s global network from October to December of 2022.

Cloudflare’s automated DDoS defenses mitigated millions of attacks in Q4 alone.

During the last week of November, we automatically detected and mitigated a 1 terabit per second (Tbps) DDoS attack targeted at a Korean-based hosting provider. We’ve taken all of those attempted attacks, aggregated, analyzed, and prepared the bottom lines to help you better understand the current threat landscape. In this report we will outline general DDoS attack trends before breaking down application-layer, networklayer, and ransom DDoS attack insights. We also explore where DDoS attacks have been observed, share patterns in attack rates and durations, and dive deeper into attack vectors and emerging threats. Finally, we provide guidance on how to proactively harden your security to better prepare for current and emerging DDoS threats.
