What is MinIO and why is version detection important in penetration testing?

MinIO is a high-performance, distributed object storage system written in Go, used for storing massive amounts of images, videos, and documents. Version detection is critical in penetration testing because knowing the exact MinIO version allows testers to identify known vulnerabilities or misconfigurations, similar to how we approach other services like Penetration Basics: Zimbra Version Detection or WebLogic Version Detection.
