Cisco Talos began an investigation after observing a DLL named "verification.google" executing from WebDAV at a Ukrainian government organization. We assess with moderate confidence that the attacks are not targeted at a particular organization, but are a part of a cryptocurrency and credentials-stealing operation using the Amatera stealer as the primary payload. Pivoting around the similar WebDAV behavior led to a second loader named "pf.ch" and allowed us to reconstruct its earlier delivery…
Attackers compromised Coder's Cloudflare infrastructure and added unauthorized registry servers that delivered malicious Terraform modules containing credential-stealing code. [...]

A new ClickFix variant dubbed TerminalFix uses fake Cloudflare CAPTCHA prompts on compromised websites to trick victims into running malicious PowerShell commands in Windows Terminal. [...]
In this article Attack chain overviewMitigation and protection guidanceLearn more Microsoft Threat Intelligence has observed a TerminalFix campaign, a variant of ClickFix, targeting organizations across multiple industries. The campaign uses compromised websites to display a fake Cloudflare CAPTCHA verification overlay that tricks users into copying and executing a malicious PowerShell command. While traditional ClickFix campaigns direct victims to the Windows Run dialog, TerminalFix campaigns…

For the latest discoveries in cyber research for the week of 10th August, please download our Threat Intelligence Bulletin. TOP ATTACKS AND BREACHES North Carolina Ports, the US authority operating the ports of Wilmington, Morehead City and others, has suffered a cyberattack that forced some operations onto manual processes. The authority claims it has contained the intrusion, but degraded systems caused delays while affected services were restored. Ryde, an electric scooter operator in…

Coding agents such as Claude Code and Cursor are vendor-signed, used all day on developer laptops, and routinely open shells, call APIs, edit files, and install helpers. That makes GenAI-adjacent alerts challenging to investigate. The parent looks trusted, while the children can still look a lot like classic high-severity activity. This article walks through one of those windows. On a macOS endpoint, Elastic Security endpoint telemetry showed shells under Claude Code that scripted a login to an…
By Yarden Porat, Check Point Research Key Points Check Point Research analyzed Cloudflare Code Mode, a technique that changes how AI agents use MCP by turning tools into a TypeScript API the model can write code against. The research uncovered five vulnerabilities in workerd, the open-source runtime behind Code Mode and Cloudflare Workers. Two were rated Critical by Cloudflare. The blast radius is broad: by Cloudflare’s own numbers, Workers is built by millions of developers,[1] serves millions…

Threat actors are increasingly exploiting legitimate cloud services to evade detection and streamline the deployment of their scam infrastructure. Cloud hosting services and decentralized networks have become primary platforms for hosting phishing pages and sites. Throughout 2025 and 2026, we have observed phishing operators steadily migrate toward platforms like Cloudflare Workers, Vercel, Netlify, GitHub Pages, and IPFS. This post analyzes the mechanics of a real-life adversary-in-the-middle …
In September 2025, Volexity conducted an incident response engagement that began after suspicious network traffic was observed from a Linux-based virtual machine appliance on a customer’s network. The virtual machine was an Egnyte Storage Sync system, which is designed to facilitate syncing local on-premise files with the cloud. Volexity discovered that instead of connecting to a domain affiliated with Egnyte, the appliance was connecting to a threat-actor-controlled domain behind Cloudflare IP…
Group-IB researchers expose a large-scale smishing and phishing operation impersonating 260+ brands across 72 countries, using fake Cloudflare error pages, geofencing, and encrypted WebSocket channels for real-time credit card theft.

Introduction Self-hosted services exposed through a reverse proxy inevitably attract automated scanners probing for misconfigurations, admin panels, and vulnerable endpoints. In this article, I show how to turn routine Traefik access logs into an active defensive control using Elastic Security and Cloudflare. I use an out-of-the-box ES|QL detection rule to identify web server discovery and fuzzing behavior. When suspicious probing patterns are detected, an automated workflow immediately blocks…
