The latest Gcore Radar report has revealed an unprecedented surge in DDoS attacks, with intensities surpassing 1.5 Tbps. Gcore successfully defended a gaming industry customer against two substantial DDoS attempts using a variety of defense strategies, including dynamic traffic shaping, anomaly detection, regular expression filters, and collaborative threat intelligence, thereby preventing service disruption without affecting user experience.

Meeting Takeaways:

1. **Significant Increase in DDoS Attack Volumes**: There has been a dramatic increase in the intensity of Distributed Denial of Service (DDoS) attacks in 2023. Initial attacks early in the year reached 800 Gbps, whereas recent attacks have seen peaks exceeding 1.5 Tbps.

2. **Gcore Radar Report Incident**: The report details two high-volume DDoS attacks targeting a gaming industry customer of Gcore. The attacks peaked at 1.1 and 1.6 Tbps respectively and involved different strategies aimed at overwhelming the customer’s network defenses.

3. **Details of the Attacks**:
– The first attack was a UDP-based DDoS that peaked at 1.1 Tbps using random UDP source ports and forged IP addresses to try to evade detection.
– The second attack was a TCP-based DDoS that consisted of SYN flood, PSH, and ACK traffic to deplete server resources, with a consistent volume of 700 Mbps and an initial peak at 1.6 Gbps.

4. **Gcore’s Response and Defense Mechanisms**:
– Gcore successfully mitigated the attacks using dynamic traffic shaping to balance network loads, anomaly detection to identify and quarantine suspicious traffic, regular expression filters to block malicious data, and collaborative threat intelligence to stay ahead of emerging threats.

5. **Industry-Wide Threat**: These attacks are part of an ongoing trend of increasingly powerful DDoS attacks across different sectors, indicating a growing risk that organizations must be prepared to counteract.

6. **Importance of DDoS Protection**: It is critical for companies to explore DDoS protection services to safeguard their networks from potential DDoS attacks and associated operational, reputational, and financial damages.

7. **Continuous Security Updates**: The shifting nature of cyber threats necessitates that businesses constantly update and adapt their security measures, leveraging information from industry alliances and threat intelligence.
