Deception to Secure Amazon S3 Buckets

Written by: Joseph Salazar, Technical Deception Engineer – Amazon Simple Storage Service (S3) provides the ability to store and serve static content from Amazon’s cloud. Businesses use S3 to store server backups, company documents, weblogs, and publicly visible content such as web site images and PDF downloads. Users organize files within S3 into “buckets,” which get assigned a URL based on a standard, predictable pattern for access to them.

Oops, They Did it Again

Last week Dow Jones, the business and financial news company that owns the Wall Street Journal, admitted that 2.2 million customers’ details were exposed due to an Amazon S3 bucket misconfiguration. They are not alone and follow similar mishaps reported by Verizon, World Wrestling Entertainment, and Scottrade. They all share a common root problem, user error that resulted in exposing the contents of their S3 buckets. There are now over one million authenticated AWS users and S3 misconfigurations are becoming all too common.
