Gcore Radar report reveals 150% surge in DDoS attacks year-on-year

**Gcore Q3–Q4 2025 Radar:** The report documents a sharp escalation in DDoS activity—1.3M attacks in Q4 2025 and peak volumes reaching 12 Tbps—driven by automated botnet capabilities (notably AISURU), expanded IoT exploitation, and easier access to attack tools; network-layer attacks (82%) are predominantly short, intense bursts while application-layer attacks trend longer; technology, financial services, and gaming are most targeted, with attack sources concentrated in Mexico, Brazil, and the United States, and the report recommends globally distributed mitigation and integrated detection/response.
