Threat actors are increasingly hosting phishing infrastructure on legitimate cloud and decentralized platforms, including Cloudflare Workers, Cloudflare Pages, Vercel, GitHub Pages, Netlify, and IPFS gateways, to evade detection and benefit from trusted shared-domain reputation and free-tier scalability. Securelist reported that defenders blocked 224,984 unique third-level domains tied to phishing on these services between August 2025 and July 2026, and identified and neutralized more than 390,000 phishing pages.
One documented campaign used a compromised website as an initial relay before directing victims to Cloudflare Workers subdomains for staging, where attackers deployed service workers and the Ultraviolet proxy library to transparently intercept traffic in an adversary-in-the-middle attack. The operation also used a browser-in-the-browser spoof to imitate Microsoft login prompts and steal credentials, MFA codes, and session tokens, underscoring how legitimate cloud infrastructure is being repurposed to support large-scale credential theft.

2 events from the most recent confirmed update back to the earliest known activity.
Over a 12-month period from August 2025 to July 2026, the report analyzed phishing URLs on cloud platforms and states that 224,984 unique third-level domains were blocked and more than 390,000 phishing pages were identified and neutralized.
The report says threat actors migrated during 2025 and 2026 toward legitimate cloud and decentralized platforms such as Cloudflare Workers, Vercel, Netlify, GitHub Pages, and IPFS to host phishing infrastructure and evade detection.

Threat actors are increasingly using **trusted platforms**—including cloud hosting and major ad networks—to deliver multi-stage phishing and scam campaigns that evade traditional URL and domain reputation controls. Recent activity includes a **three-step malvertising chain** delivered via **Facebook paid ads** that redirects victims through a decoy site (e.g., a fake Italian restaurant page) before landing on a **tech support scam (TSS) kit** hosted on **Microsoft Azure** infrastructure (including `web.core.windows.net`). Researchers reported rapid infrastructure churn, with **100+ domains rotated in seven days**, and targeting focused on **U.S. users** with activity concentrated on weekdays. Parallel enterprise-focused campaigns are hosting phishing infrastructure on **Microsoft Azure Blob Storage**, **Google Firebase**, and **AWS CloudFront**, using **redirect chains, CAPTCHA gates, and QR codes** to bypass automated analysis and email defenses. Analysis highlighted the use of **Adversary-in-the-Middle (AiTM)** phishing-as-a-service kits—**Tycoon2FA**, **Sneaky2FA**, and **EvilProxy**—to steal credentials and **session tokens** even when MFA is enabled. Separately, researchers documented a “clean email” approach to steal **Dropbox** credentials: benign-looking procurement-themed emails deliver **PDF attachments** that hide clickable elements (e.g., via *AcroForms* and `FlateDecode`), which then route victims to a second-stage file hosted on **Vercel Blob** and ultimately to a fake Dropbox login page that captures credentials and collects victim telemetry (IP address, location, and device details).

Threat actors are increasingly abusing free web hosting services such as Cloudflare Pages to host phishing portals that impersonate banking, insurance, and healthcare organizations. These phishing sites are designed to harvest sensitive information including credentials, security questions, and multifactor authentication codes. Attackers benefit from the speed, scale, and resilience provided by free hosting, as well as the use of mainstream messaging platforms like Telegram for exfiltration, making detection and takedown efforts more challenging for defenders. Modern phishing kits have evolved into sophisticated platforms that enable even low-skilled threat actors to deploy convincing credential-harvesting sites rapidly. These kits often include features such as admin panels, real-time credential delivery, proxy capabilities for MFA bypass, and antibot systems to evade security researchers. The accessibility and advanced capabilities of these kits, combined with the use of free hosting and messaging services, have significantly lowered the barrier to entry for large-scale phishing campaigns targeting organizations and individuals alike.

Cybercriminals are increasingly utilizing advanced Phishing-as-a-Service (PhaaS) kits to conduct large-scale, targeted phishing campaigns that impersonate trusted brands and institutions. These kits, which have doubled in number over the past year, enable even less-skilled attackers to deploy sophisticated attacks at scale by incorporating features such as URL obfuscation, MFA bypass, CAPTCHA abuse, and the use of malicious QR codes and attachments. Threat analysts have observed a surge in new PhaaS entrants, including Cephas, Whisper 2FA, and GhostFrame, alongside established kits like Tycoon 2FA and Mamba 2FA. Attackers are also leveraging AI, social engineering, and polymorphic techniques to evade detection, making it increasingly difficult for organizations to defend against these threats with static security controls alone. Technical analysis reveals that phishing infrastructure is evolving to include fake verification pages, such as counterfeit Cloudflare Turnstile challenges, which act as intelligent traffic filtering gates. These pages use browser fingerprinting, geolocation, and proxy detection to selectively deliver malicious payloads to high-confidence victims while evading security researchers and automated defenses. The fake verification pages closely mimic legitimate branding and user experience, including fabricated Ray IDs and links to real policy documents, to build trust and bypass scrutiny. Security experts recommend adopting layered defenses, including phishing-resistant MFA, continuous monitoring, and integrated email security, to counter these increasingly sophisticated phishing operations.
