Gcore Radar Report Reveals 41% Surge In DDoS Attack Volumes

Luxembourg, September 25th, 2025/CyberNewsWire/--Gcore, the global edge AI, cloud, network, and security solutions provider, today announced the findings of its Q1-Q2 2025 Radar report into DDoS attack trends.

DDoS attacks have reached unprecedented scale and disruption in 2025, and businesses need to act fast to protect themselves from this evolving threat. The report reveals a significant escalation in the total number of DDoS attacks and their magnitude, measured in terabits per second (Tbps).

It also highlights a clear shift: attackers are growing more strategic, blending brute-force volume with precise application-layer manipulation.

Key Insights From Q1-Q2 2025

·      Attack volumes increased by 41% compared to Q1-Q2 2024, evidencing dangerous long term growth trends predicted in prior Radar reports.

·      The largest attack peaked at 2.2 Tbps in Q1-Q2, surpassing the 2 Tbps peak recorded in late 2024.

·      DDoS attacks are becoming longer in duration but more harmful.

·      Attackers are shifting focus to financial services and tech, with tech overtaking gaming as the most targeted sector.

·      DDoS attacks at the application layer have increased by 10% from Q3-Q4 2024 to Q1-Q2 2025.

·      The total number of DDoS attacks climbed from 969,000 in H2 2024 to 1.17 million in H1 2025.

Recent Data Shows Shift Toward Longer Sustained Assaults

Attacks shorter than 10 minutes have decreased by about 33%, while those lasting between 10 and 30 minutes have nearly quadrupled. While previous reports highlighted the dominance of very short, intense DDoS attacks, this change indicates that attackers are adapting to the improved automatic detection and mitigation systems employed by companies to handle brief attacks. By extending attack durations, threat actors can circumvent these temporary defense thresholds, cause more extensive damage, and test infrastructure resilience over time.

Multi-vector attacks have also increasingly become a preferred tactic of attackers. By masking malicious activity within seemingly legitimate traffic, attackers complicate detection and extend their window to cause damage. This shift toward more sophisticated attacks underscores the need for an equally layered defense approach that anticipates attacker strategies and protects critical digital assets holistically.

Data Indicates Rise in Attacks on Vulnerable Sectors

Gaming is no longer the dominant target it once was. Its share of total DDoS attacks has dropped significantly (30% in the last year). This notable decline suggests attackers are shifting focus to other sectors such as tech (attacks increased by 15%) and financial services (attacks increased by 15%). These sectors are favored targets because they may be less protected against threat actors and have higher disruption potential.

The Domino Effect of Cyberattacks

Hosting providers, in particular, have become prime targets due to their role supporting SaaS, e-commerce, gaming, and financial clients. An attack on one hosting provider can have dangerous ripple effects: massive service outages and reputation damage to dozens of dependent companies.

Geographical Distribution of DDoS Attacks

With a presence that spans six continents, Gcore can accurately track the geographical sources of DDoS attacks. Gcore derives these insights from the attackers’ IP addresses and the geographic locations of the data centers where malicious traffic is targeted.

Although the United States and the Netherlands remain top sources for attacks (as found in previous Radar reports), Hong Kong is a new source of threats. Hong Kong now accounts for 17% of all network-layer and 10% of application-layer attacks. These findings indicate that attackers are expanding into emerging areas, highlighting the need for proactive and adaptive defenses across diverse regions.

Emerging Origins of Attacks

The rapid increase in application layer attacks (28% to 38% from Q3-Q4 2024 to Q1-Q2 2025) also reveals an overall trend toward multi-layered attacks targeting web application and API vulnerabilities, which particularly impact sectors with a high degree of customer interaction (ranging from e-commerce and online banking to logistics and public services).
