Kaspersky reveals drop in DDoS attacks but cryptomining is on the rise
aspersky has revealed the
K number of DDoS attacks detected by Kaspersky DDoS Prevention in Q4 2020 increased slightly in comparison to the same period of 2019 . However , it is 31 % less compared to Q3 2020 . Unfortunately , this drop can be connected to the growing interest in cryptocurrency mining .
As people began to spend more time online in 2020 , it resulted in a boom of DDoS attacks and in the fourth quarter , attacks on educational institutions continued . However , in Q4 2020 there were only 10 % more attacks than in Q4 2019 . And compared to Q3 2020 , the number of attacks in Q4 2020 fell by 31 %, while Q3 2020 also saw a drop compared to Q2 .
Experts suggest that this can be caused by a surge in cryptocurrency costs .
As a result , cybercriminals may have had to ‘ re-profile ’ some botnets so that C & C servers , that are typically used in DDoS attacks , could repurpose infected devices and use their computing power to mine cryptocurrencies instead . This is further proved by KSN statistics .
Throughout 2019 , as well as in the beginning of 2020 , the number of cryptominers was dropping . However , from August 2020 the trend changed , with the amount of this form of malware increasing slightly and reaching a plateau in Q4 .
Report reveals cyber-risk to critical and industrial infrastructure reaches all-time high
new report from Nozomi Networks Labs finds
A cyberthreats to industrial and critical infrastructure have reached new heights as threat actors double down on high value targets .
With industrial organisations ramping connectivity to accelerate Digital Transformation and remote work , threat actors are weaponising the software supply chain and ransomware attacks are growing in number , sophistication and persistence .
“ This report leaves no doubt that the time for action is now ,” said Nozomi Networks Co-founder and CTO , Moreno Carullo . “ The recent Oldsmar , Florida , water system attack and the on-going SolarWinds investigation are dramatic reminders that the critical infrastructure and other systems that we rely on are vulnerable and at constant risk of attack . Understanding the effectiveness of defences against the emerging threat and vulnerability landscape is vital to success .”
Nozomi Networks ’ latest OT / IoT Security Report , gives cybersecurity professionals an overview of the OT and IoT threats analysed by Nozomi Networks Labs security research team .
Nozomi Networks CEO , Edgard Capdevielle , said : “ While threats may be on the rise , the technologies and practices to defeat them are available today . We encourage organisations to act quickly to implement the recommendations in this report . It ’ s never been more important or more possible to take the necessary steps to detect and defend critical infrastructure and industrial operations .” u www . intelligentciso . com
