38TB of data accidentally exposed by Microsoft AI researchers

**Executive summary:** Wiz Research discovered that a Microsoft AI research GitHub repository published an Azure Account SAS token with excessive scope and full-control permissions, exposing ~38 TB of private data—including workstation backups containing secrets, private keys, passwords, and 30,000+ internal Teams messages—and creating significant supply-chain and persistence risks because the token was long-lived and model files (TensorFlow ckpt using pickle) could enable remote code execution.
