By
A hacking method that involves abusing a legitimate Cloudflare feature to steal people’s data and persist on compromised endpoints is gaining popularity, a report published by cybersecurity researchers from GuidePoint.
The feature being abused is called Cloudflare Tunnels, which allow users to create secure, outbound-only connections to the Cloudflare network for web servers and applications. The setup is simple, and the configuration is extensive, as users get plenty of access controls, gateway configurations, team management, and user analytics.
Once set up, the tunnel become exposed to the internet and can be used for different things such as sharing resources and similar.
