Cloudflare’s Services Gaining Popularity for Phishing Schemes


December 4, 2024 by our News Team

Cloudflare's website optimization services and online tools have been increasingly misused for phishing attacks and other malicious activities, with their domains pages.dev and workers.dev being popular choices due to their association with legitimate platforms and use of Cloudflare's reputation.

  • Cloudflare offers a generous free offering of their Cloudflare Pages service.
  • Cloudflare is actively working to combat malicious activities on their platforms.
  • Users can protect themselves by staying informed and exercising caution when dealing with unfamiliar or suspicious content.


Cloudflare, a company known for its website optimization services and online tools, has recently been facing an increase in the misuse of its services for various schemes. Specifically, the domains pages.dev and workers.dev provided by Cloudflare have become popular choices for phishing attacks and other malicious activities. This trend can be attributed to the fact that these domains are associated with legitimate platforms and leverage Cloudflare’s reputation to lend credibility to the schemes.

One of the services often exploited for these schemes is Cloudflare Pages, which allows users to host static web pages on Cloudflare’s systems. Criminals take advantage of the generous free offering of this service to launch phishing attacks, such as fake Microsoft Office365 login sites. According to Fortra, a cybersecurity company, the number of attacks using Cloudflare’s services has increased from 460 in 2023 to over 1370 by mid-October 2024. This means an average of 137 incidents per month, and the actual number could be even higher considering unreported cases.

The association of these domains with a reputable entity makes it difficult for many spam filters to identify them as malicious. As a result, these domains can bypass filters and reach users’ inboxes, increasing the effectiveness of the attacks. While Cloudflare has measures in place to swiftly identify and remove these schemes, sometimes their tools may not be sufficient to prevent them from causing harm to potential victims in a timely manner.

As always, it is crucial for users to exercise caution when dealing with messages from unknown sources or those that require unusual steps to perform certain actions. Being vigilant and skeptical of unfamiliar or suspicious content can go a long way in protecting oneself from falling victim to these schemes.

In conclusion, Cloudflare’s services have unfortunately become a breeding ground for malicious activities, with phishing attacks on the rise. The company is working diligently to combat these schemes, but it is equally important for users to stay informed and remain cautious in their online interactions. By staying vigilant and adopting safe online practices, we can collectively mitigate the risks associated with these exploits.
