Unveiling the Surge: Global DDoS Threat Landscape Report Q2 2023

A recent report from Cloudflare reveals that sophisticated Distributed Denial of Service (DDoS) attacks worldwide surged to 5.4 trillion in the second quarter of 2023, marking a 15% uptick from the first quarter. Despite many of these attacks being of short duration, the recovery process proved to be prolonged, significantly impacting daily business operations.

Key Insights:

  • Cryptocurrency firms experienced an unprecedented 600% surge in attacks globally, while the management consulting and non-profit sectors faced heightened targeting due to their web traffic.
  • The United States encountered the highest number of attacks, followed by Canada and Singapore.
  • The prevalence of HTTP DDoS attacks increased by 15% quarter-over-quarter, with instances noted in Mozambique, Egypt, and Finland.

Contributing Factors:

  • Pro-Russia hacker groups, including REvil, Killnet, and Anonymous Sudan, targeted Western websites amid the Ukraine conflict. In June alone, they executed approximately 10,000 DDoS attacks against various sectors.
  • A disclosed zero-day vulnerability (CVE-2022-26143) in March exposed Mitel Business phone systems to UDP amplification DDoS attacks, reaching an alarming 220 billion percent.
  • The proliferation of botnets such as Tsunami and AndoryuBot played a role in the upsurge of DDoS attacks, including one peaking at 1.4 terabytes per second against an American ISP, involving around 11,000 IP addresses and employing a Mirai-variant botnet.

Discovery of a New Attack Tool:

  • In the midst of escalating threats, the relatively unknown Russian group NoName has enhanced the DDoSia attack toolkit to launch more intense DDoS attacks against Western nations.
  • Developed in Golang, the tool can target systems on Windows, Linux, and macOS, featuring an added layer of security to obfuscate the list of targets, posing a challenge to the analysis process.


  • The DDoS threat landscape is evolving into a more intricate scenario, necessitating measures beyond traditional security practices. Organizations are urged to implement multi-layered defenses and DDoS protection systems to counter such attacks effectively. Recommendations include enabling firewalls and adopting robust internet security solutions to ensure safer online browsing.
