EBS - Loot Public EBS Volumes

To find the S3 bucket region we can use another trick, this time with cURL.

curl -I https://mega-big-tech.s3.amazonaws.com

us-east-1 is the bucker region in the header as we can see

From the account ID and region we can now go to the amazon console in personal account and go to EC2 and look for public snapshots.
