NETSCOUT Systems has released its DDoS Threat Intelligence Report for the second half of 2025, revealing a surge in large-scale, coordinated cyberattacks driven by increasingly sophisticated threat actors, resilient botnets and compromised IoT infrastructure.
According to the report, more than eight million distributed denial-of-service (DDoS) attacks were recorded globally across 203 countries and territories during the period. Some attacks reached unprecedented scale, peaking at 30 terabits per second (Tbps), signalling a new phase of hyper-scale cyber threats that continue to challenge global mitigation efforts.
The report also highlights the rapid growth of DDoS-for-hire services, which are lowering the barrier to entry for cybercriminals and enabling a wider pool of threat actors to launch attacks. This trend is increasing operational risk for enterprises and digitally connected organisations worldwide.
Beyond sheer attack volume, NETSCOUT warns that adversaries are increasingly deploying reconnaissance techniques and adaptive evasion strategies that undermine traditional defence models. The company says organisations must adopt intelligent, automated protection systems to keep pace with evolving threats.
