Everyone breathes a sigh of relief when they hear "no customer data was exposed," but that's a big mistake. This recent Navy Federal Credit Union leak is a perfect example of why. Exposing 378 GB of internal Tableau data, user emails, and system configurations is like handing a burglar the architectural blueprints to your building. It tells them where the weak points are and who to target with spear phishing. Operational data is just as critical as customer data, and misconfiguration remains one of the most common, and avoidable, security failures.

TL;DR
📦 An unsecured server exposed 378 GB of the credit union's internal backup files.
🛡️ Fortunately, no sensitive customer PII was directly included in the leak.
🗺️ The data did, however, act as a "roadmap," revealing internal system structures and formulas.
🎯 This kind of operational data leak enables highly targeted phishing campaigns against employees.
