DDoS attacks are a growing threat. Quarterly DDoS statistics reveal different countries appear on the list with more and more attacks.

What’s even worse is that: 

In reality, just a small share of the attacks are reported. Meanwhile, they become more complex, featuring more threat vectors. Their intensity increases, the frequency shifts, the number of attackers grows, and the targeted industries change.

All these dynamics make DDoS attack statistics almost impossible to keep track of. 

But don’t worry!

At The High Court, we’ve curated the vital DDoS attack statistics from 2020 and before to keep you up to speed. As a bonus, we’ll also address DDoS law and a few other matters of interest.

Let’s dive right in.

Global DDoS Statistics 2020

Before we dig deep into the stats, we should clarify the difference between DoS vs DDoS. While DoS is only an attack between one machine and another machine, DDoS uses a group of devices to attack one host.

Usually, when we think of what does DDoS mean in terms of strength, we think of their volumetric form, which is measured in Gbps or Tbps. In terms of size, the attacks are addressed as per the large volume of traffic designed to overpopulate a circuit. Another way of addressing the attacks is in terms of intensity (measured in Mpps). High-intensity attacks are aimed at particular infrastructures. 

With that in mind:

1. China is on top of the list of attacks and targets, with 71.20% and 72.83%.

Neustar offers its customers a Protection Services DDoS program that mitigates attacks. The company’s findings show the number of attacks in 2020 increased by more than two and a half times from the 2019 figure. The industry as a whole witnessed a dramatic jump in the number of attacks.

5. The number of DDoS attacks per year will rise to 15.4 million by 2023.

(Source: Cisco)

Cyber attacks are becoming more common globally. There are a growing number of breaches and records exposed per breach. Overall, the global DDoS attack between 100 Gbps and 400 Gbps Y/Y from 2018 to 2019 has grown by a mind-blowing 776%

What’s more:

The total number of DDoS attacks is expected to double from 7.9 million in 2018 to 15.4 million by 2023.


Types of DDoS Attacks

6. SYN flooding was the most common type in Q3 2020 and accounted for 94.6% of all attacks.

(Source: SecureList)

The distribution of DDoS attack types for Q3 2020 remained fairly constant. SYN flooding was the main tool (94.6%), virtually unchanged from Q2. ICMP attacks accounted for 3.4%, TCP attacks accounted for 1.4%, and HTTP flooding accounted for less than 0.1% of attacks.

7. 91.06% of the attacks in Q3 2020 lasted up to four hours.

(Source: SecureList)

The average length of the latest DoS attacks has shortened. The share of long (100–139 hours) attacks decreased by 0.08 p.p, while the share of ultra-long attacks went up slightly by 0.18 p.p. The longest-lasting attacks registered in Q3 2020 were over ten days (246 and 245 hours). Overall, the overwhelming majority of attacks (91.06%) lasted up to four hours.

8. 95% of attacks in the first half of 2020 featured more than a single threat vector.

(Source: Neustar) 

95% of all attacks featured more than a single threat vector. Only 5% featured a single vector. The number of extremely complex attacks (four vectors and more) was equivalent to 17%. The majority of attacks featured two threat vectors (43%) and three threat vectors (35%). 

Key takeaway:

There are more DDoS attackers because the higher the number of vectors is, the lower the number of actors who can control such threats. Click To Tweet

9. Neustar recorded an 81% increase in attack intensity in the first half of 2020.

Cybersecurity Ventures estimates that the costs of global cybercrime will grow by 15% per year over the next five years. It is estimated to reach $10.5 trillion annually by 2025, up from $3 trillion in 2015

19. Reported cybercrime in the US represents only 10-12% of the total.

(Source: CybersecurityVentures)

Due to embarrassment, the belief that DDoS Federal crime law enforcement can’t help, and fear of reputational harm, the vast majority of attacks are not reported. The unit chief at the FBI’s Internet Crime Complaint Center (IC3) stated that reported cybercrimes represent only 10-12% of the total number of crimes committed in the US each year.


Wrap Up

2020 oversaw a shift in the top ten countries with the most DDoS attacks. However, China remains on the top daily DDoS attacks worldwide list. From the projections for the following years, it is clear that the number of attacks will keep growing.

The current trend in attack type is intentionally shorter and planned not to be detected. At the same time, new records are broken in terms of attack intensity, and the attacks become more complex to mitigate. Like malware and ransomware, DDoS attacks are on the rise.

As a result, DDoS attack statistics show the protection and mitigation market will be experiencing growth.
