Report
In 2024, DDoS attackers didn’t reinvent their playbook—they perfected it. Fast, short, sub-10Gbps attacks continued to dominate, as they have for years, underscoring a persistent and evolving threat model where disruption is cheap, accessible, and alarmingly effective. Download now to see how better coordination creates stronger protection.
We at Corero have been tracking DDoS trends for years. And while some of the trends feel familiar—fast, short attacks still dominate—there’s nuance that demands attention. The frequency is up. The volume is climbing again. The middle of the attack spectrum is thinning out. What’s left is a blend of opportunistic pressure and strategic brute force, fueled by automation and constant adaptation.
