Introduction Amazon S3 (Simple Storage Service) has been at the center of some of the most damaging data breaches in cloud history. From exposed customer databases to leaked government documents, misconfigured S3 buckets remain a goldmine for attackers — and a nightmare for defenders. In 2026, S3 misconfigurations haven’t disappeared. They’ve evolved.
