Before Alex even finished their morning coffee, the "visitor" had used those keys to: Spawn hundreds of servers to mine digital currency. Download private data from the app's users. Lock Alex out of their own account. The Lesson: Alex learned that credentials aren't just files; they are . Protecting them means: Never storing keys in plain text on a server. Using Roles:

1. Immediately rotate all AWS credentials
2. Audit CloudTrail for unauthorized API calls
3. Review application for successful file read attempts
4. Patch vulnerability before restoring service

Here's the decoding process:
