In 2025, DDoS attacks kept scaling in ways that look less like random spikes and more like repeatable playbooks across botnet networks. When you compare the fastest rising traffic floods to the downtime they trigger, the gap is often bigger than you would expect. Let’s look at the statistics behind what defenders saw and what attackers kept changing.
Key Takeaways
- In Q4 2023, Cloudflare mitigated 20 million DDoS attacks, averaging 55,000 per day
- UDP floods used in 62% of volumetric DDoS attacks per Cloudflare 2023
- 98% of DDoS attacks mitigated within 10 seconds by Cloudflare autodefense 2023
- Global DDoS attack volume hit 15.4 million in 2023 per NETSCOUT, costing $2.5B in mitigation
- 40% of DDoS attacks targeted financial services in 2023 per Akamai
This year saw a surge in DDoS attacks, with brief bursts driving most of the downtime.
