🔍 Researchers disclosed two denial-of-service techniques, collectively dubbed CDN Tsunami, that exploit how major CDNs translate client-facing HTTP/3 into backend HTTP/1.1 requests, amplifying small attacker traffic to large origin load. The study tested Alibaba, Baidu, Cloudflare, CloudFront, Fastly, and Tencent, finding widespread susceptibility to a bandwidth amplification variant and partial susceptibility to a connection-amplification variant. Vendor mitigations are applied at CDN edges, and the work will be presented at a September 2026 symposium.

🔍 New analysis by Ontinue details VoidLink, a Linux-based command-and-control framework that generates implant binaries for credential theft, data exfiltration and stealthy persistence across cloud and enterprise hosts. The agent fingerprints AWS, GCP, Azure, Alibaba and Tencent environments and adapts its behavior, loading modular plugins for container escape and kernel-level stealth. Researchers identified unusual development artefacts — structured "Phase X:" labels, duplicated numbering, verbose debug logs and embedded documentation — that suggest parts of the implant were written or assisted by a large language model coding agent with limited human review.
