All objects by default are private. Only the object owner has permission to access them. However, the object owner can optionally share objects with others by creating a presigned URL to grant time-limited permission to download the objects. Anyone who receives the presigned URL can then access the object.

Important: Presigned URLs are valid only for the specified duration.

Hint 1
Find and check somethingstrange.

URL is presigned by the command:
# aws s3 presign s3://<BUCKET>/<OBJECT> --expires-in 3600
