cf-check: CloudFlare Checker written in Go
Check a Host is Owned by Cloudflare.
▶ go get -u github.com/dwisiswant0/cf-check
▶ echo “uber.com” | cf-check
▶ cf-check -d <FILE>
Usage of cf-check:
Set the concurrency level (default: 20)
Show Cloudflare only
-d Print domains instead of IP addresses
The goal is that you don’t need to do a port scan if it’s proven that the IP is owned by Cloudflare.
▶ subfinder -silent -d uber.com | filter-resolved | cf-check | anew | naabu -silent -verify | httpx -silent
