Third-Party SaaS Breach Exposes 137K School Staff Records

Infinite Campus suffered a significant data breach through their Salesforce instance, demonstrating how third-party cloud services can become attack vectors that compromise sensitive organizational data. The ShinyHunters gang successfully accessed personal information of 137,000 school staff members, including contact details and job information, highlighting the risks of storing sensitive data in external systems. While the company's customer databases remained secure, the breach underscores the critical need for comprehensive third-party risk management and data protection controls across all cloud services.
