DDoS report reveals that the complexity and volume of attacks continues to grow

Link11 has released findings from its annual DDoS Report, which revealed a rising number of multivector and cloud computing attacks during 2019.

The latest Link11 DDoS report is based on data from repelled attacks on web pages and servers protected by Link11’s Security Operations Center (LSOC).

Key findings from the annual report include:

The data showed that the frequency of DDoS attacks depends on the day of the week and time of the day, with most attacks concentrated around weekends and evenings. More attacks were registered on Saturdays, and between 4pm and midnight on weekdays.

There was also a number of new amplification vectors registered by the LSOC last year including WS–Discovery, Apple Remote Management Service and TCP amplification, with registered attacks for the latter doubling compared to the first six months of the year. The LSOC also saw an increase in ‘carpet bombing’ attacks in the latter part of 2019, which involves a flood of individual attacks that simultaneously target an entire subnet or CIDR block with thousands of hosts. This popular method spreads manipulated data traffic across multiple attacks and IPs. The data volume of each is so small that it stays under the radar and yet the combined bandwidth has the capacity of a large DDoS attack.
