There has been a sharp increase in DDoS attacks as a result of the crisis in Ukraine since February.
DDoS attacks are designed to interrupt network resources used by businesses and organisations and prevent them from functioning properly.
They become even more dangerous if the compromised systems are in government or financial sectors, as these services being unavailable has knock-on effects that affect the wider population.
Compared to figures from quarter 4 of 2021, which had been considered the all-time highest number of DDoS attacks detected by Kaspersky solutions, quarter 1 2022 saw the total number of DDoS increase by 46%, growing 4,5-times compared to the same quarter in 2021.
The amount of “smart” or advanced and targeted attacks also showed a notable growth of 81% compared to the previous record from Q4 2021.
The attacks were not only performed at scale but were also innovative. Examples include a site mimicking the popular 2048 puzzle game to gamify DDoS attacks on Russian websites, and a call to build a volunteer IT army in order to facilitate cyberattacks.
Further investigation by Kaspersky revealed that an average DDoS session lasted 80-times longer than those in Q1 2021. The longest attack was detected on March 29 with an atypically long duration of 177 hours.
“In Q1 2022 we witnessed an all-time high number of DDoS attacks. The upward trend was largely affected by the geopolitical situation,” comments Alexander Gutnikov, security expert at Kaspersky. “What is quite unusual is the long duration of the DDoS attacks, which are usually executed for immediate profit.
“Some of the attacks we observed lasted for days and even weeks, suggesting that they might have been conducted by ideologically motivated cyberactivists.
“We’ve also seen that many organisations were not prepared to combat such threats. All these factors have caused us to be more aware of how extensive and dangerous DDoS attacks can be. They also remind us that organisations need to be prepared against such attacks.”
