Cloud security firm Wiz has discovered that Chinese AI startup DeepSeek left a publicly accessible database unprotected. This database exposed sensitive information, including user chat histories, secret API keys, and system logs. This exposure could have allowed unauthorized individuals to access confidential data and potentially take control of the entire system. After being notified, DeepSeek secured the data in less than an hour. However, it remains unclear whether any unauthorized parties had accessed the information before the issue was resolved. This incident raises concerns about the security of AI services, particularly in managing cloud databases. It highlights the urgent need for effective security measures to protect sensitive data and ensure user safety.
