Overview of Recent DDoS Attack Mitigation
Gcore , a provider of edge AI, cloud, network, and security solutions, successfully mitigated a substantial Distributed Denial of Service (DDoS) attack. The attack reached a peak bandwidth of 6 Tbps and a packet rate of 5.3 Bpps.
The attack targeted a hosting provider in the gaming sector, indicating a broader trend in increasingly sophisticated DDoS campaigns against digital infrastructure. The methodology was consistent with the AISURU botnet, known for recent high-impact incidents globally.
Peak traffic: 6 Tbps Packet rate: 5.3 Bpps Main protocol: UDP, typical of volumetric floods Duration: 30-45 seconds Geographic concentration: 51% of sources originated in Brazil and 23.7% in the US
The attack reached a peak bandwidth of 6 Tbps and a packet rate of 5.3 Bpps.
This attack aligns with findings from the Gcore Radar report Q1-Q2 2025 , which noted a 41% increase in DDoS attacks in one quarter and a significant rise in attacks on tech companies.
The attack's characteristics reflect a tactic in modern DDoS campaigns: short-burst, high-intensity attacks to test infrastructure resilience. This highlights the necessity for adaptive mitigation, edge-layer filtering, and Layer 7 behavioral analysis.
Gcore's DDoS Protection solution absorbed and neutralized the attack without service interruption, utilizing its 210+ Points of Presence and a filtering capacity exceeding 200 Tbps. This underscores the need for integrated, AI-driven DDoS defense strategies capable of real-time response and deep traffic inspection.
