The Ukrainian Ministry of Defense, whose site has been taken down following the attacks, said that its "Website was probably attacked by DDoS: an excessive number of requests per second was recorded." "Starting from the afternoon of February 15, 2022, there is a powerful DDOS attack on a number of information resources of Ukraine," Ukraine's State Service for Special Communication and Information Protection added.

The Ukrainian Ministry of Defense, whose site has been taken down following the attacks, said that its "Website was probably attacked by DDoS: an excessive number of requests per second was recorded. Technical works on restoration of regular functioning are carried out." While the Ukrainian defense ministry site has been knocked out, Oschadbank's website is still accessible although customers cannot log in to their online banking accounts.

Advanced DDoS attacks that are typically targeted, known as smart attacks, rose by 31% in the same period. Further, 73% of DDoS attacks in Q3 2021 were multi-vector attacks that combined multiple techniques to attack the targeted systems.

Microsoft this week revealed that it had fended off a record number of distributed denial-of-service attacks aimed at its customers in 2021, three of which surpassed 2.4 terabit per second. One of the DDoS attacks took place in November, targeting an unnamed Azure customer in Asia and lasted a total of 15 minutes.

Microsoft says its Azure DDoS protection platform mitigated a massive 3.47 terabits per second distributed denial of service attack targeting an Azure customer from Asia in November. Two more large size attacks followed this in December, also targeting Asian Azure customers, a 3.25 Tbps UDP attack on ports 80 and 443 and a 2.55 Tbps UDP flood on port 443.

The Nobel Foundation and the Norwegian Nobel Institute have disclosed a cyber-attack that unfolded during the award ceremony on December 10, 2021. The Nobel prize ceremony is being live-streamed from Oslo and Stockholm, and as such, DDoS attacks can interrupt the video feed and possibly even blemish the prestige of the institution.

The global DDoS protection and mitigation market size is expected to grow from $3.3 billion in 2021 to $6.7 billion by 2026, at a Compound Annual Growth Rate of 15.1% from 2021 to 2026, according to ResearchAndMarkets. The major factors fueling the DDoS protection and mitigation market include growing demand for sophisticated security solutions, evolving regulatory landscape, and growing volumes of business data across industries.

An IRC bot strain programmed in GoLang is being used to launch distributed denial-of-service attacks targeting users in Korea. "Additionally, the DDoS malware was installed via downloader and UDP RAT was used."

Anycast's advantages were understood in principle, but it took the DDoS attack in 2007 to shift the dial for DNS Anycast as big Content Delivery Networks, and top-level domain registrars adopted the technology at speed. "For Anycast to work, you have to know how Internet global routing and BGP works. But we were DNS guys, not network guys. We had to learn it the hard way over several years. Even now, 50 per cent of the work at RcodeZero DNS is maintaining perfect global routing," agrees Darilion.

Extortion or ransom DDoS attacks started to become a new threat in August 2020 and grew bigger and more complex since then. One of the largest DDoS attacks that Cloudflare mitigated lasted for 60 seconds and came from a botnet with 15,000 systems that hurled close to 2Tbps of junk packets at a customer.
