Security News > 2020 > April > Average bandwidth of DDoS attacks increasing, APIs and applications under attack

There has been an increasing number of high-volume attacks in Q1 2020, with 51 attacks over 50 Gbps. The average bandwidth of attacks also rose, reaching 5,0 Gbps versus 4,3 Gbps in the same quarter in 2019.

Key findings Maximum bandwidth nearly doubles: In Q1 2020, the maximum bandwidth nearly doubled in comparison to the previous year; the biggest attack stopped was 406 Gbps. In Q1 2019 the maximum bandwidth peaked at 224 Gbps. Complex multi-vector attacks rising: The share of multi-vector attacks rose to 64% in Q1 2020 up from 47% in Q1 2019.

There were 19 attacks that used 10 or more different DDoS vectors, compared to no reported attacks of this scale in 2019.

DDoS attackers increasingly abuse public cloud services: Nearly the half of all DDoS attacks in Q1 2020 used public cloud server-based botnets, compared to 31% in the previous year.

APIs and applications under attack: As companies build new applications and services from multiple sources using APIs, they are becoming increasingly vulnerable to Layer 7 attacks, which are typically 'low and slow' compared to network layer attacks.
