title: Amazon S3 storage: possible to list public folders in a private bucket?
body: <p>I have a Amazon S3 Bucket with all settings in the default mode. When I go to my Bucket Permissions tab and look to the section <strong>Public access</strong> / <strong>Everyone</strong>, all options are empty, so everything is private.</p>
  
  <p>Now I make a folder with a very long random sha1-hash, I upload some files and subfolders in this folder and make the whole folder public. Is it possible to detect (list) this folder?</p>
  
  <p>When I go to my bucket in the browser
  <a href="https://s3.xxx.amazonaws.com/my-private-bucket" rel="nofollow noreferrer">https://s3.xxx.amazonaws.com/my-private-bucket</a>
  and I see: <code>&lt;Code&gt;AccessDenied&lt;/Code&gt;</code>. </p>
  
  <p>That looks good. But maybe there is another way to detect my public folder?</p>
