- Long-term analysis of DDoS trends reveals evolving attack patterns and dataset limitations.
- Study advocates for greater collaboration between academia, industry, and operators to combat DDoS effectively.
What happened: Long-term DDoS analysis reveals distinct trends and collaboration needs
A new study provides an in-depth examination of Distributed Denial-of-Service (DDoS) attack trends, analysing over 10 datasets from academia and industry spanning 4.5 years. The research categorises DDoS attacks into two major types: direct-path (DP) attacks and reflection-amplification (RA) attacks, offering insights into their evolution and prevalence.
Direct-path attacks target systems directly, often using spoofed IP addresses, while reflection-amplification attacks exploit third-party services to overwhelm victims with amplified responses.
The study highlights differences in datasets collected by network telescopes, honeypots, and industry observatories, pointing out that no single dataset captures the full DDoS landscape. Industry partners like Netscout and Akamai, alongside academic observatories such as UCSD Network Telescope, show varying trends in attack frequencies and peaks.
Booter takedowns by law enforcement were found to have limited short-term impact, suggesting the need for more systemic solutions. The researchers call for better data-sharing frameworks and deeper collaboration across sectors to achieve a comprehensive view of the DDoS threat.

Why it’s important
The findings underline the persistent and evolving nature of DDoS attacks, which remain a significant cybersecurity challenge. Reflection-amplification attacks, for instance, surged during specific periods due to new attack vectors and limited implementation of Source Address Validation (SAV) by operators.
The study emphasises that addressing spoofing — a core enabler of many DDoS attacks — is critical to mitigating their impact.
Importantly, the research reveals that academic and industry datasets offer distinct perspectives on the DDoS landscape, and their combination is essential for effective countermeasures. Recommendations for researchers include collaborating with industry to access diverse data, while operators are encouraged to adopt SAV and support real-time measurement systems.
Industry players can enhance visibility by standardising terminology and easing access to historical reports. This study underscores the urgent need for collective action to close data gaps and strengthen defences against future DDoS attacks.
