Security News > 2022 > April > Multi-vector DDoS attacks on the rise, attackers indiscriminate and persistent

The report indicates that 2021 was another record year for DDoS attacks, as Comcast Business DDoS Mitigation Services identified and helped defend 24,845 multi-vector attacks targeting Layers 3,4, and 7 simultaneously.

Overall, 69 percent of customers experienced DDoS attacks, a 41 percent increase over 2020, while 55 percent were targets of mulit-vector attacks, as opposed to in 2020 where most customers experienced single vector attacks.

The data also shows that DDoS attackers were indiscriminate and persistent as no verticals were spared and everyone was fair game - from tow truck drivers to churches, government, utilities, IT companies, online gambling sites, and manufacturing operations.

Attacks on education customers followed the cadence of a typical school year, starting strong in January before taking a significant dip over the summer when schools were out, while the financial sector experienced a 3X uptick in attacks during November and December compared to the rest of the year.

Other key findings on multi-vector DDoS attacks Attacks on information technology customers grew steadily, ending the year at 10X the January numbers.

69 percent of all multi-vector attacks lasted under 10 minutes, as short duration attacks are harder to detect and give IT organizations less time to respond, quickly overwhelming defenses.
