Insecure Cloud Bucket Leaks 2.5 M Student‑Loan Records

Attackers exploited a publicly accessible cloud storage bucket that was misconfigured without proper authentication controls. Over a short period they downloaded the entire contents of the bucket, exfiltrating 2.5 million student‑loan records that included names, Social Security numbers, dates of birth, loan balances, and bank‑account details. The breach was discovered after the data appeared on underground forums, prompting an emergency response from the loan servicer.

For defenders, the incident underscores the high cost of lax cloud‑security hygiene. Unrestricted bucket permissions bypass traditional perimeter defenses and give threat actors direct access to sensitive data. Organizations must enforce strict IAM policies, enable bucket-level encryption, implement continuous configuration monitoring, and deploy anomaly detection on cloud access logs to prevent similar exposures and meet regulatory obligations.
