How a Two-Character Typo Exposed 50 Million User Records

In this episode, Lucas and Luna dissect a real-world data breach that stemmed from a simple two-character typo in an access control file. They walk through how a missing 'not' in an AWS S3 bucket policy left 50 million user records exposed for months. Lucas explains the technical details of the misconfiguration, how it was discovered by a security researcher, and the cascading consequences for the company. Luna challenges whether the root cause was really the typo or a broken code review process. They discuss practical mitigations like infrastructure-as-code linting, automated policy validation, and the principle of least privilege. The episode is a focused case study on how tiny mistakes in cloud security configurations can have massive implications, and what engineering teams can do to catch them before they reach production. #DataBreach #CloudSecurity #AWSS3 #AccessControl #InfrastructureAsCode #SecurityMisconfiguration #CodeReview #DevSecOps #LeastPrivilege #SecurityAudit #PolicyValidation #TypoBug #ProductionIncident #EngineeringCulture #SoftwareEngineering #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
