Cloud anti-DDoS vendor Link11 has released its DDoS findings for Q4 2018, revealing that the volume and complexity of attacks continued to grow during the final quarter of 2018.   While Link11’s Security Operations Center (LSOC) registered 13,910 attacks in Q4 (12.7 percent down compared to Q3), the average attack volume grew by 8.7 percent to 5Gbps, and 59 percent of attacks used multiple attack vectors.

Key findings of Link11’s Q4 DDoS report include:

The LSOC also observed that attacks occurred most frequently on Saturdays and Sundays, with the level of attacks declining during the business week. Attackers targeted organizations most frequently between 4 pm and midnight Central European Time, with attack volumes at their lowest between 6 am and 10 am CET.

"The increase in the impact and complexity of attacks continues unabated," said Marc Wilczek, COO of Link11. "When faced with DDoS bandwidths well over 100 Gbps and multi-vector attacks, traditional IT security mechanisms are easily overwhelmed, and unprotected companies risk serious business disruption, loss of revenue and even fines.  To stop these attacks disrupting business operations, organizations need proactive protection that tracks and responds to evolving attack scenarios and patterns automatically, using advanced machine-learning techniques.”
