The seller announces the sale of the full source code of Cloudflare, including the main source code repository, edge infrastructure components, a filtering rule engine, and traffic optimization modules.

The seller positions the material as a complete structural code base of one of the largest CDN and DDoS-mitigation providers. The description specifically emphasizes that the alleged repository can be used for searching for zero-day vulnerabilities, analyzing bypass methods, edge normalization bugs, and auditing internal network structures.

The announcement states that the repository includes several major categories:

• Edge Network Logic - edge network core routing configurations, custom BGP orchestration, and internal backbone network architecture; • WAF & Rules Engine - proprietary Lua/Rust logic underlying Cloudflare's Web Application Firewall and bot mitigation filters; • Control Plane & Microservices - backend components of the control panel, global synchronization protocols, and infrastructure asset deployment code; • Internal Tooling & Automation - network policy automation tools related to recent infrastructure leaks.

The seller claims that the repository structure is hosted in a sandboxed environment where buyers can verify the content of the leak before the transaction.
