Hackers Abuse Cloudflare Services for Sophisticated Phishing Attacks

The attacks, which began emerging in early 2025, leverage Cloudflare Workers and Pages to host malicious content that easily bypasses traditional security filters due to the trusted nature of Cloudflare’s infrastructure. Cybersecurity experts have identified a troubling new trend where threat actors are exploiting legitimate Cloudflare services to orchestrate highly convincing phishing campaigns. Hunt.io security researchers identified this campaign after observing a 43% increase in phishing incidents utilizing trusted cloud infrastructure over the past quarter. This technique allows attackers to maintain persistence while evading detection, as the phishing infrastructure leverages Cloudflare’s legitimate reputation and robust infrastructure to remain operational.
