According to data presented by the Atlas VPN team, in the first half of this year, distributed denial of service (DDoS) attacks increased by 11% compared to H1 2020 figures of a total of 5.4 million. If current trends continue, DDoS attacks are expected to reach a record 11 million by the end of this year.
DDoS attacks use a botnet (a network of compromised computers) to flood the victim’s IT infrastructure with many requests, disrupting a victim’s service. Cybercriminals can infect any computer or smart device, making it part of a botnet. As the number of IoT devices in the world grows, such attacks become easier to carry out than ever before.
DDoS attacks were at their peak at the beginning of this year. There were 972,000 DDoS attacks in January alone, which is higher than any other month. In June, the DDoS attacks reached their lowest point in the first half of 2021, dropping to 759,000.
Regardless of the slowdown in attacks, the largest DDoS attack took place in June. Cybercriminals launched a terabyte-class attack on a German ISP and implemented a DNS reflection / amplification vector. The attacks had a bandwidth of 1.5Tbps – an increase of 169% compared to the most significant attack in H1 2020.
Teleworking has opened up new opportunities for cybercriminals. Since the onset of the pandemic, the world has become increasingly dependent on connectivity and web services, making them a lucrative target for threat actors.
With 283,516 DDoS attacks, wired telecommunications companies were among the most affected industries, followed by computing, hosting and related services (195,258 attacks) and wireless telecommunications companies (84,151 attacks).
The figures are based on the Netscout Threat Intelligence Report, which covers DDoS attack trends in the first half of 2021.
