Welcome to the 23rd edition of Cloudflare’s Quarterly DDoS Threat Report. This report offers a comprehensive analysis of the evolving threat landscape of Distributed Denial of Service (DDoS) attacks based on data from the Cloudflare network. In this edition, we focus on the third quarter of 2025.

Cloudflare has deployed a new protection to address a vulnerability in React Server Components (RSC). All Cloudflare customers are automatically protected, including those on free and paid plans, as long as their React application traffic is proxied through the Cloudflare Web Application Firewall (WAF). Cloudflare Workers are inherently immune to this exploit. React-based applications and frameworks deployed on Workers are not affected by this vulnerability.

The API supply chain is the new security blind spot. Attackers no longer need to breach your APIs directly; they can target the third-party services that connect to them. These unmanaged dependencies are now the shortest path to your sensitive data. The recent Mixpanel incident is a stark reminder of that fact.

The definition of the "edge" is changing. For years, security teams have focused on the traditional perimeter: web applications, public APIs, and user interfaces. We built firewalls, deployed WAFs, and established strict access controls to keep bad actors out. But with the rapid adoption of Agentic AI, the perimeter has expanded. Today, your "edge" isn't just where users connect to your apps; it's where AI agents connect to your data.

AI deepfakes are making fraud even more sophisticated. Learn how to stay safe from deepfake scams. Scammers are using deepfake technology to replicate your child's voice in a kidnapping hoax, catfish with AI-generated video dates, and impersonate executives to steal millions. Learn how to spot deepfake fraud, and use Avast Scam Guardian to help verify what's real before it's too late.

This is the final post in a three part series examining the past, present and future of workflows. In the first two posts, we explored where workflows came from and what defines an intelligent workflow. This final article looks ahead. The goal is to understand how workflows will evolve in the coming years and why they will become central to how organizations run, make decisions, and adapt.

Sha1-Hulud is back with a new evolution of its supply-chain attack that targets development environments via Node Package Manager (npm). npm is a very popular package manager for Node.js that provides millions of predeveloped packages of code to be used by JavaScript developers for access to millions of packages. This campaign trojans unsecured npm packages with malicious code that is automatically executed when developers using that package update to the trojaned version.

Modern organizations often use GitLab as a core version control system (VCS), making it one of the most essential systems for DevOps. Given the critical nature of the data stored here, thorough evaluation of risks and implementing data protection best practices are a must. According to the Shared Responsibility Model, GitLab provides security for the underlying infrastructure, while the user’s duty is to keep data protected. More about GitLab’s Shared Responsibility Model.

In the first installment of our Inside the Agent Stack series, we examined the design and security posture of agents built with Azure Foundry. Continuing the series, we now focus on Amazon Bedrock AgentCore, a managed service for building, deploying, and orchestrating AI agents on AWS.

According to our 2025 State of the Underground report, ransomware attacks rose by nearly 25% in 2024, and the number of ransomware group leak sites jumped 53%. This surge sets the stage for a critical question: if compromised, should you pay ransomware demands or not? The stakes are enormous, including downtime, data loss, brand damage, and legal risk all hang in the balance.
