Gcore Stops Two Powerful DDoS Attacks Including one of 1.6 Tbit/s

Gcore boothGcore, a European content delivery network (CDN) provider that specializes in a range of IT services such as hosting, content delivery, edge computing, public cloud, cybersecurity, and AI solutions, recently demonstrated its strong cybersecurity skills. Gcore says it successfully defended a gaming firm customer against two consecutive Distributed Denial of Service (DDoS) attacks earlier this month.

Notable for their intensity and ingenuity, these DDoS attacks had the potential to completely disrupt online services, according to Gcore, but Gcore was able to efficiently neutralize them, guaranteeing the client’s ongoing services.

The two DDoS attacks carried out on the gaming firm were noteworthy for their scope and methods, added Gcore. The strength of the first of them reached a startling 1.6 Tbit/s. This size may overload the majority of servers, sometimes forcing them down due to an excessive amount of traffic. But these DDoS attacks were unique because they used new strategies. The use of random UDP (User Datagram Protocol) source ports by the attackers suggests that their goal was to circumvent the conventional cyber security filtering techniques. The attackers also forged source IP addresses to conceal their identity. The second DDoS attack was TCP-based and lasted over nine hours, while the first was quick but intensive, with the goal of flooding the network with data.

Gcore’s DDoS protection capabilities were responsible for anomaly detection, dynamic traffic shaping, and quarantine measures. This included using cooperative threat information and creating regular expression-based filters. These precautions were successful in preventing the cyberattacks and guaranteeing the continued functioning and security of the client’s online services.

Gcore CEO Andre Reitenbach discussed the situation and emphasized the seriousness of these kinds of DDoS attacks. “By any measure, a DDoS attack of more than 1.5 Tbps is huge and represents a major threat to any company,” Mr. Reitenbach said. He underlined how thorough Gcore‘s fortifications are, noting that they not only fend off DDoS attacks but also guarantee the availability of Internet services. Reitenbach also brought up the fact that cybercriminals are always coming up with new ways to get around cybersecurity defenses.

Seriousness of Cyberthreats

Further highlighting of this incident’s relevance may be found in the latest Gcore Radar Report (Q1 & Q2 2023). DDoS attacks across a variety of sectors have dramatically increased, according to this analysis, which provides insights into cybersecurity trends and the health of the DDoS protection industry today. These DDoS attacks had an average strength of around 800 Gbps in the beginning of 2023. Since then, however, this number has doubled, indicating a concerning increase in the seriousness of these cyberthreats.

The UDP flood attack was also noted in the study as the most typical kind of DDoS attack. Although the majority of DDoS attacks in the first half of the year lasted for less than four hours, there were a few that lasted for many days, with the longest attack ever recorded lasting more than seven days.

Gcore‘s protection against these powerful DDoS attacks would emphasize not just the company’s cybersecurity skills but also the constantly changing nature of cyberthreats. Companies, especially those that depend on Internet services, are more susceptible to these kinds of DDoS attacks, thus having a strong and flexible cyber protection strategy is essential.
