How has the landscape of IoT botnets and DDoS attacks evolved since 2017?

While IoT botnets remain a threat, attackers have diversified their tactics. They now utilize a wider range of compromised devices, including cloud instances and mobile devices. Attack volumes have continued to increase, and new attack vectors, such as application-layer DDoS attacks, have emerged. Mitigation techniques have also evolved, with increased reliance on cloud-based DDoS protection services and advanced traffic filtering.
