New Report Warns of 68% Of Actively Serving Phishing Kits Protected by CloudFlare

A new security report reveals a troubling reality about the state of online phishing operations. Recent research has uncovered over 42,000 validated URLs and domains actively serving phishing kits, command-and-control infrastructure, and malicious payload delivery systems.

The scale and sophistication of these operations represent a significant departure from traditional phishing attempts.

Rather than simple misspelled domain names and poorly written messages, modern phishing campaigns now operate with the efficiency and organization of legitimate technology companies.

The threat landscape has fundamentally transformed from ad-hoc individual attacks into coordinated criminal enterprises.

These operations leverage professional infrastructure management, robust uptime commitments, and engineered evasion techniques that rival enterprise-grade security systems.

SicuraNext security analysts identified that the infrastructure supporting these campaigns demonstrates remarkable operational maturity, with a 96.16% mean DNS resolution rate, indicating highly stable and well-maintained malicious domains.

SicuraNext security researchers noted that Cloudflare serves as the primary infrastructure provider for phishing operations worldwide.

The analysis reveals that 17,202 of the 25,305 tracked malicious domains, representing 68% of all phishing infrastructure, operate through Cloudflare’s network.

This concentration exists because Cloudflare’s free tier offers threat actors zero upfront cost, world-class DDoS protection, and proxy services that effectively mask the actual hosting servers.

The thousands of malicious domains clustered on AS13335, Cloudflare’s primary autonomous system number, have made the platform the de facto home base for phishing operations globally.

MFA Bypass Infrastructure and Defense Evasion

The most dangerous development involves Phishing-as-a-Service platforms, such as EvilProxy and Tycoon 2FA.

Unlike traditional phishing kits that simply steal passwords, these services operate as adversary-in-the-middle proxies, positioning themselves between victims and legitimate services.

When users authenticate, the kit intercepts their session while forwarding credentials to the real service, then captures the resulting session cookie.

This approach completely bypasses multi-factor authentication protections. These sophisticated platforms incorporate multiple evasion technologies.

Geofencing blocks security researchers by IP range, while user-agent-based cloaking restricts content visibility to specific device types, often displaying malicious pages only on mobile browsers.

Developer tools detection immediately stops pages from functioning when security researchers open inspection tools. Cloudflare CAPTCHA filters automatically filter out automated security scanners.

The analysis identified 20 distinct phishing clusters sharing identical infrastructure fingerprints, rotated IP ranges, identical registrars, and matching evasion patterns, demonstrating coordinated, professionally-managed operations rather than opportunistic attacks.
