How We Protected a Famous Gaming Company Against a 450+ Gbps DDoS Attack

Year on year, we’re seeing a concerning uptick in both the average and peak intensities of DDoS attacks. 

The max DDoS attack volume was 300 Gbps in 2021, 650 Gbps in 2022, and 800 Gbps in 2023

In 2023, it’s no longer surprising to encounter attacks with magnitudes ranging from 300–400 Gbps—these have become the new norm for businesses. Just recently, our team at Gcore successfully thwarted a massive 450+ Gbps attack aimed at a well-known gaming company.

The assault focused on ports used for online gaming. Cybercriminals attempted to mimic the patterns of legitimate user traffic in order to mount a potent attack. Leveraging our real-time traffic analytics, we identified and neutralized the threat right from its initial request. Attempts to disguise malicious activity as genuine user traffic fail when faced with Gcore’s advanced DDoS Protection measures.

How Gcore Thwarted the Attack

Gcore’s security experts immediately detected and neutralized the attack, avoiding any disruptions to the client’s servers. We used a distributed infrastructure and collaborated with peering partners to diffuse the incoming traffic across various locations, minimizing the impact of the attempted attack.

We also used UDP Challenge-Response (UCR) technology—a sophisticated authorization mechanism—as an additional layer of defense. In this system, we send a challenge message to each connecting client. The client must respond with a message processed through a secret function shared between us and the client. Since we know the shared function, we can instantly verify whether the incoming message is legitimate. Clients providing a valid response can be trusted and are allowed to access protected resources.
