## Cloud Resources

Good start on S3 buckets (AWS), blobs (Azure), cloud storage (GCP), R2 Buckets (Cloudflare), ...

[Domain.glass](https://domain.glass/) can give good info from the domain name like if Cloudflare is present

<https://buckets.grayhatwarfare.com/> for buckets information. Try looking for `id_rsa`
