Attackers use brute forcing on the bucket URL to identify the correct URL.

• A. DNS Tunneling
• B. Phishing
• C. Directory Traversal
• D. Brute-Forcing URL

Answer: (D)

Brute-forcing URLs is about discovering valid web resources by systematically trying many possible URL paths or object names and watching which ones respond in a way that reveals a real resource. When a bucket URL is predictable, an attacker can automate requests across a range of candidate bucket names or keys and identify the one that exists and is accessible, effectively locating the correct URL. This matches the idea of brute-forcing the bucket URL to find the right endpoint, since the attacker is intentionally enumerating possibilities to uncover a valid resource. Other techniques described involve different goals: DNS tunneling hides data inside DNS queries, phishing relies on social engineering to steal credentials, and directory traversal attempts to access files outside the allowed directory by manipulating paths—not the same endpoint-enumeration activity.
