Cloudflare CDN Scanner

This repository contains a scanner for checking Cloudflare-backed targets and related DNS behavior. It includes both the Go implementation under go/ and the packaged Windows executables in the repository root.

Included Files

• scanner.exe - Go-based Windows executable.
• scanner_py.exe - Python/PyInstaller Windows executable.
• go/ - Go source, build scripts, and the scanner engine.
• python/ - Python source and packaging files.
• cidrs.txt, domains.txt - sample input lists used by the scanner.

Quick Start

1. Build the Go scanner:

   go build -o scanner.exe ./cmd/scanner

2. Build the cross-platform Go matrix:

   cd go
   pwsh ./build_matrix.ps1

   Or on Linux, macOS, or Termux:

   cd go
   bash ./build_matrix.sh

   This produces:

   • scanner-android-arm64 for Termux / Android arm64
   • scanner-linux-armv7 for Linux arm
   • scanner-darwin-arm64 for macOS arm64
   • scanner-windows-amd64.exe for Windows amd64
   • scanner-linux-amd64 for Linux amd64

3. Run the scanner and provide an input file such as domains.txt.

4. Review the generated output files in the repository root, including:

   • reachable_<timestamp>.txt
   • full_log_<timestamp>.txt
   • poisoned_dns_<timestamp>.txt
   • hijacked_dns_<timestamp>.txt
   • raw_ip_dump_<timestamp>.txt

Notes

• The scanner performs active network probing, so only use it on targets you are authorized to test.
• Some build outputs are intentionally ignored by git, but the two packaged executables are kept trackable in the repository root. are we there yet ?
