If it continues to develop, DDoS attacks may exceed the threshold of 10 million attacks last year.
Researchers recorded approximately 2.9 million DDoS attacks in the first quarter of 2021, an increase of 31% over the same period in 2020.
Netscout’s Atlas Security Engineering and Response Team (ASERT) predicted last year that the high DDoS number recorded in 2020 will continue into 2021. Researchers now report that the 900,000 attack mark was exceeded in all three months of the first quarter. They said that if this activity is established, the DDoS attack activity will be set to exceed the 10 million attack threshold recorded last year.
Researchers say this kind of activity is unusual because January and February are usually the slowest months for DDoS attacks. In 2021, they observed 972,000 attacks in January alone, surpassing the record of the largest number of attacks in a month set in May last year.
They pointed out that the scale of DDoS attacks “remains relatively stable.” No large megabit attacks were found. However, attackers are looking for new ways to make their attacks faster and harder to mitigate. Most (42%) DDoS attacks lasted 5 to 10 minutes; in less than five minutes, the proportion of all DDoS attacks dropped from 24% to 19%. Those who last longer stay the same.
By the third quarter of 2020, healthcare organizations have suffered about 7,000 DDoS attacks, 10,000 in the fourth quarter of this year, and 8,400 in the first quarter of this year, an increase of 53% from the first quarter of 2020. Researchers also report that this number is 41%. In the past three quarters, attacks on education services have increased, reaching 45,000 in the first quarter of 2021 alone.
