As we enter 2024, Gcore has launched its newest Gcore Radar report, a twice-annual publication by which the corporate releases inner analytics to trace DDoS assaults. Gcore’s broad, internationally distributed community of scrubbing facilities permits them to comply with assault developments over time. Learn on to study DDoS assault developments for Q3–This fall of 2023, and what they imply for growing a strong safety technique in 2024.
Gcore’s Key Findings
DDoS assault developments for the second half of 2023 reveal alarming developments within the scale and class of cyberthreats.
Unprecedented Assault Energy
The previous three years have led to a >100% annual enhance in DDoS peak (registered most) assault quantity:
- In 2021, the height capability of DDoS assaults was 300 Gbps
- In 2022, it elevated to 650 Gbps
- In Q1–Q2 of 2023, it elevated once more to 800 Gbps
- In Q3–This fall of 2023, it surged to 1600 Gbps (1.6 Tbps)
Notably, the soar in H2 of 2023 means the cybersecurity trade is measuring DDoS assaults in a brand new unit, Terabits.

This illustrates a big and ongoing escalation within the potential injury of DDoS assaults, a pattern Gcore expects to see proceed in 2024.
Assault Period
Gcore noticed assault lengths various from three minutes to 9 hours, with a mean of about an hour. Normally, brief assaults are tougher to detect as they do not for correct visitors evaluation because of information shortage, and since they’re tougher to acknowledge, they’re additionally tougher to mitigate. Longer assaults require extra assets to battle, requiring a robust mitigation response; in any other case, the chance is extended server unavailability.

Predominant Assault Varieties
UDP floods proceed to dominate, constituting 62% of DDoS assaults. TCP floods and ICMP assaults additionally stay common at 16% and 12% of the entire, respectively.
All different DDoS assault sorts, together with SYN, SYN+ACK flood, and RST Flood, accounted for a mere 10% mixed. Whereas some attackers might use these extra refined approaches, the bulk are nonetheless centered on delivering sheer packet quantity to take down servers.

The variation in assault strategies necessitates a multifaceted protection technique that may shield in opposition to a variety of DDoS strategies.
International Assault Sources
This international unfold of assault sources demonstrates the borderless nature of cyber threats, the place attackers function throughout nationwide boundaries. Gcore recognized numerous assault origins within the latter half of 2023, with the US main at 24%. Indonesia (17%), the Netherlands (12%), Thailand (10%), Colombia (8%), Russia (8%), Ukraine (5%), Mexico (3%), Germany (2%,) and Brazil (2%) make up the highest ten, illustrating a widespread international risk.
Geographical assault supply unfold |
The geographic distribution of DDoS assault sources supplies essential info for creating focused protection methods and for shaping worldwide policy-making aimed toward combating cybercrime. Nevertheless, figuring out the placement of the attacker is difficult because of the usage of strategies like IP spoofing and the involvement of distributed botnets. This makes it tough to evaluate motivations and capabilities, which might differ from state-sponsored actions to particular person hackers.
Focused Industries
Essentially the most-targeted industries in H2 of 2023 spotlight the affect of DDoS assaults throughout numerous sectors:
- The gaming trade stays probably the most affected, enduring 46% of the assaults.
- The monetary sector, together with banks and playing companies, got here in second at 22%.
- Telecommunications (18%,) infrastructure-as-a-service (IaaS) suppliers (7%,) and pc software program firms (3%) had been additionally considerably focused.
DDoS assaults by affected trade |
Since the earlier Gcore Radar report, attackers have not modified their focus: The gaming and monetary sectors are notably attention-grabbing to attackers, seemingly because of their monetary positive aspects and consumer affect. This underscores a necessity for focused cybersecurity methods within the most-hit industries, like countermeasures for particular gaming servers.
Evaluation
The info from the latter half of 2023 highlights a worrying pattern within the DDoS assault panorama. The rise in assault energy to 1.6 Tbps is especially alarming, signaling a brand new degree of risk for which organizations should put together. For comparability, even a “humble” 300 Gbps assault is able to disabling an unprotected server. Paired with the geographical distribution of assault sources, it is clear that DDoS threats are a severe and international situation, necessitating worldwide cooperation and intelligence sharing to mitigate probably devastating assaults successfully.
The vary in assault durations means that attackers have gotten extra strategic, tailoring their approaches to particular targets and goals:
- Within the gaming sector, for instance, assaults are comparatively low in energy and period however extra frequent, inflicting repeated disruption to a particular server with the purpose of disrupting the participant expertise to pressure them to modify to a competitor’s server.
- For the monetary and telecom sectors, the place the financial affect is extra fast, assaults are sometimes greater in quantity with size extremely variable.
The continued concentrating on of the gaming, monetary sectors, telecommunications, and IaaS industries displays the strategic alternative of attackers to choose companies whose disruption has a big financial and operational affect.
Conclusion
The Gcore Radar report for Q3–This fall of 2023 serves as a well timed reminder of the ever-evolving nature of cyberthreats. Organizations throughout sectors should put money into complete and adaptive cybersecurity measures. Staying forward of DDoS threats requires a eager understanding of the altering patterns and techniques of cyber attackers.
