As we enter 2024, Gcore has launched its newest Gcore Radar report, a twice-annual publication during which the corporate releases inside analytics to trace DDoS assaults. Gcore’s broad, internationally distributed community of scrubbing facilities permits them to comply with assault traits over time. Learn on to find out about DDoS assault traits for Q3–This fall of 2023, and what they imply for growing a strong safety technique in 2024.
Gcore’s Key Findings
DDoS assault traits 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 improve 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 leap in H2 of 2023 means the cybersecurity business is measuring DDoS assaults in a brand new unit, Terabits.

This illustrates a big and ongoing escalation within the potential harm 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 more durable to detect as they do not for correct site visitors evaluation as a consequence of information shortage, and since they’re more durable to acknowledge, they’re additionally more durable to mitigate. Longer assaults require extra sources to struggle, requiring a strong mitigation response; in any other case, the danger is extended server unavailability.

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

The variation in assault strategies necessitates a multifaceted protection technique that may shield towards a variety of DDoS strategies.
World Assault Sources
This world 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 world menace.

The geographic distribution of DDoS assault sources supplies essential info for creating focused protection methods and for shaping worldwide policy-making geared toward combating cybercrime. Nonetheless, figuring out the situation of the attacker is difficult as a consequence of using strategies like IP spoofing and the involvement of distributed botnets. This makes it tough to evaluate motivations and capabilities, which might range from state-sponsored actions to particular person hackers.
Focused Industries
Probably the most-targeted industries in H2 of 2023 spotlight the influence of DDoS assaults throughout numerous sectors:
- The gaming business stays essentially the most affected, enduring 46% of the assaults.
- The monetary sector, together with banks and playing providers, got here in second at 22%.
- Telecommunications (18%,) infrastructure-as-a-service (IaaS) suppliers (7%,) and pc software program corporations (3%) have been additionally considerably focused.

Since the earlier Gcore Radar report, attackers have not modified their focus: The gaming and monetary sectors are significantly fascinating to attackers, doubtless as a consequence of their monetary positive factors and consumer influence. 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 stage of menace 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 world situation, necessitating worldwide cooperation and intelligence sharing to mitigate doubtlessly devastating assaults successfully.
The vary in assault durations means that attackers have gotten extra strategic, tailoring their approaches to particular targets and targets:
- Within the gaming sector, for instance, assaults are comparatively low in energy and period however extra frequent, inflicting repeated disruption to a selected server with the objective 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 influence is extra speedy, assaults are sometimes increased in quantity with size extremely variable.
The continued focusing on of the gaming, monetary sectors, telecommunications, and IaaS industries displays the strategic selection of attackers to choose providers whose disruption has a big financial and operational influence.
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 methods of cyber attackers.
Gcore DDoS Safety has a confirmed file of repelling even essentially the most highly effective and sustained assaults. Join Gcore DDoS Safety to guard what you are promoting from regardless of the 2024 DDoS panorama brings.
