Cloudflare’s Q4 2025 report shows that Bangladesh has become the largest source of DDoS attacks, moving up two spots from the previous quarter. The report indicates a trend of increased DDoS traffic originating from Asia and South America, primarily due to compromised infrastructure, not the location of the attackers.
After Bangladesh, Ecuador and Indonesia took the second and third spots, respectively. Argentina moved up 20 places to fourth, showing a significant increase. Cloudflare observed that such rapid changes often signal newly weaponized botnets, exploited hosting services, or insecure IoT devices used for large-scale attacks.
