DDoS attacks fell by nearly a third (31%) in Q4 2020 compared to Q3, according to new figures from Kaspersky.
Researchers believe this reduction is linked to soaring cryptocurrency costs, with cybercriminals increasingly focusing on cryptomining. Kaspersky statistics have shown that while the number of cryptominers has declined throughout 2019 and early 2020, as of August 2020, this form of malware has increased slightly.
With cryptocurrency mining becoming increasingly lucrative, it is likely that many cybercriminals have re-profiled some botnets to allow C&C servers, typically used in DDoS attacks, to reassign infected devices and use their power. calculator to mine cryptocurrencies instead.
Last month, Avira revealed that it detected a 53% increase in crypto-mining software in the last quarter of 2020, linked to the surge in Bitcoin’s value.
Despite this quarterly decline in the fourth quarter of 2020, DDoS attacks were still 10% higher compared to the same period in 2019. This is due to the continued increase in DDoS attacks in 2020, with cyber villains exploiting the number growing number of DDoS attacks. number of people and time spent online since the introduction of COVID-19 social distancing restrictions. Kaspersky noted that many educational institutions have been targeted by this tactic in the last three months of 2020, including several schools in Massachusetts and Laurentian University in Canada.
Alexey Kiselev, Business Development Manager in the Kaspersky DDoS Protection team, said: “The DDoS attack market is currently affected by two opposing trends. On the one hand, people still rely heavily on the stable work of online resources, which can make DDoS attacks a common choice for criminals. However, with cryptocurrency prices soaring, it may be more profitable for them to infect certain devices with minors. As a result, we see that the total number of DDoS attacks in Q4 has remained fairly stable. And we can predict that this trend will continue in 2021. “
