The year 2025 has already witnessed a surge in DDoS attacks driven by Internet of Things (IoT) devices. Major cybersecurity firms like Cloudflare and Qualys have reported record-high attacks, such as a new all-time large-scale DDoS that peaked at 5.6 terabits per second. Emerging botnets, including Murdoc, utilize vulnerabilities in devices like routers and cameras to conduct these attacks. Security firms Trend Micro and Infoblox have also identified similar threats, indicating a troubling proliferation of IoT-driven malicious activities within a few weeks of the new year.
A post on Tuesday from content-delivery network Cloudflare reported on a recent distributed denial-of-service attack that delivered 5.6 terabits per second of junk traffic, a new record for the largest DDoS ever reported.
The botnet discovered by Trend Micro, utilizing variants of Mirai and Bashlite, has been delivering large-scale DDoSes primarily targeting locations in Japan, showcasing the growth of IoT-driven attacks.
Researchers at Infoblox revealed a botnet of 13,000 devices, predominantly MikroTik routers, which is prepared to engage in malicious activities such as sending out deceptive spam emails.
Qualys reported a 'large-scale, ongoing operation' named the Murdoc Botnet, which exploits vulnerabilities in AVTECH Cameras and Huawei routers for installing a Mirai variant and conducting DDoS attacks.
