Distributed denial of service (DDoS) attacks, incidents that aim to overwhelm a network until the server crashes against educational resources grew exponentially this spring when compared to the previous year cybersecurity vendor Kaspersky has revealed.
For each month from January to June 2020, the number of DDoS attacks affecting educational online resources increased by at least 350% when compared to the corresponding months in 2019.
In DoS attack, cybercriminals attempt to overwhelm a network server with requests for services so that the server crashes – denying users access. While DoS attacks involve only one attack computer, what typically occurs is a distributed DDos attack. These involve a “botnet” – a series of infected computers that can carry out tasks simultaneously. DDoS attacks are particularly problematic because they can last anywhere from a couple days to a few weeks, causing disruptions to organisations’ operations and – in the case of educational resources – denying students and staff access to critical materials.
With more people than ever online due to the pandemic this spring and summer, networks became a preferred target of an attack.
In fact, globally, the total number of DDoS attacks increased by 80% in Q1 2020 when compared to Q1 2019. Moreover, attacks on educational resources accounted for a large portion of this growth.
DDoS attacks weren’t the only cyberthreats faced by educators and students this past spring. From January to June 2020, 168,550 unique Kaspersky users encountered increase number of various threats distributed under the guise of popular online learning platforms/video conferencing applications (Moodle, Zoom, edX, Coursera, Google Meet, Google Classroom, Blackboard).
Educators also encountered an increasing number of phishing pages and emails exploiting these same platforms, also putting them at risk of downloading various threats.
Alexander Gutnikov, Security Expert, Kaspersky, said: “Remote learning became a necessity for billions of students this past spring and many educational institutions were forced to make the transition with little or no preparation. The ensuing increase in the popularity of online educational resources coupled with this lack of preparedness made the educational sector an ideal target for cyberattacks. Moving forward this fall, as many schools and universities plan to conduct classes online-at least part of the time – it’s critical these organisations take steps to secure their digital learning environments.”Click below to share this article
