A report published by Link11 suggests there has been a 33 percent increase in the number of DDoS attacks in H1 2021. Between January and June, the Link11 Security Operations Centre (LSOC) recorded record numbers of attacks compared to the same period last year. The report also found that between Q1 2021 and Q2 2021 there was a 19 percent increase in DDoS campaigns, some of which were over 100 Gbps in attack volume.

The key findings from the report are:

  • The number of attacks continued to rise: +33 percent increase year-on-year compared to H1/2020.
  • DDoS attacks are increasing: +19 percent in Q2 2021 compared to Q1 2021.
  • Overall attack bandwidth remained high: 555 Gbps in maximum attack volume.
  • Sharp increase in attack bandwidth: +37 percent increase in H1/2021 compared to H1/2020.
  • Number of high-volume attacks > 100 Gbps in H1/2021: 28

Criminals targeted those organizations and institutions that were in high demand during the global pandemic, such as vaccination websites, e-learning platforms or portals and businesses IT infrastructure.

LSOC also suggests that the use of extortion emails has reached critical levels. Employees have received malicious emails from a multitude of different senders. The frequency of these campaigns has increased, ransom demands have skyrocketed and LSOC is warning that they could continue well into Q3 2021.

According to Link11’s security experts, the intensity and regularity of extortion emails has noticeably increased. The scale of DDoS activity far exceeds any from previous years and the number of businesses experiencing serious security breaches has risen sharply.

Although the threat level of DDoS attacks has remained high and security providers have provided persistent warnings, LSOC believes some companies are still lack the relevant security solutions to prevent an attack. In a number of cases, organizations have been found to be completely unprotected and operations have been brought to a standstill. As threat levels continue to rise LSOC recommends businesses take this opportunity to conduct a thorough review of their cyber security posture. They are also warning if you fall victim to a DDoS attack do not respond to extortion attempts and call in a specialist as soon as a breach has been detected.
