Abusing S3 Bucket Permissions

This article details how attackers and hunters can identify and abuse misconfigured AWS S3 buckets: discovery techniques (HTML inspection, brute-force, Google dorking, DNS caching, reverse IP lookup, GitHub tools), testing of permissions via AWS CLI and URLs (READ, WRITE, READ_ACP, WRITE_ACP, FULL_CONTROL), an example vulnerable policy with Action set to '*', and recommended mitigations such as disabling public access, proper bucket policies/ACLs, IAM roles, presigned URLs, and enabling logging.
