Cloudflare says the number of hyper-volumetric HTTP DDoS (distributed denial of service) attacks recorded in the third quarter of 2023 surpasses every previous year, indicating that the threat landscape has entered a new chapter.

DDoS attacks are a type of cyberattack that involves directing large volumes of garbage traffic or large numbers of bogus requests to targeted servers hosting apps, websites, and online services to overwhelm and make them unavailable to legitimate visitors.
