title: Encrypted Cloudfront script getting injected to our site and causing js errors in our logs
body: <p>A javascript error started popping up in our logs and exploded into tens of thousands of errors over a short period - probably 2-3 ours - then disappeared.  The original of the error was traced back to this cryptic javascript file: <a href="https://d1ui18tz1fx59z.cloudfront.net/js/all/pd2.js?v=17" rel="nofollow">https://d1ui18tz1fx59z.cloudfront.net/js/all/pd2.js?v=17</a>.  A similar error popped up again yesterday for another 2-3 hours, same file, but a new version parameter: <a href="https://d1ui18tz1fx59z.cloudfront.net/js/all/pd2.js?v=18" rel="nofollow">https://d1ui18tz1fx59z.cloudfront.net/js/all/pd2.js?v=18</a>.  </p>
  
  <p>Anyone have any clue what this file is or how to decode it?  Is is a possible XSS attack?  How is it throwing errors inside our js stack?</p>
