The CEH Cloud Computing module identifies cloud APIs as one of the most critical attack surfaces in public cloud environments. APIs control provisioning, configuration, authentication, and management of cloud resources.

A vulnerability in a cloud API can allow attackers to:

Bypass authentication

Escalate privileges

Access or modify cloud resources

Create or delete services

Option B is therefore correct.

Option A relates to availability, not API flaws.

Option C is managed by the provider and unrelated to APIs.

Option D would require key compromise, not just API weakness.

CEH strongly emphasizes API security as a top cloud risk.

Insecure communication is defined in CEH’s mobile and IoT security modules as the failure to encrypt sensitive data transmitted between a device and a server. When applications use plain HTTP instead of HTTPS, all traffic—including authentication tokens, user identifiers, and session data—can be monitored and altered by an attacker through network sniffing or man-in-the-middle attacks. CEH emphasizes that insecure transport channels represent one of the most common and critical weaknesses in mobile ecosystems, allowing attackers to harvest credentials or inject malicious commands. Security misconfiguration refers to improper server settings, while SSL pinning issues involve certificate validation bypassing. Insufficient input validation pertains to application-side data validation. None of these align as directly as insecure communication, which precisely describes the unencrypted data exposure.

SQL injection testing commonly involves using tautology-based payloads such as 1 OR 1=1, which force SQL queries to evaluate as true. CEH explains that this confirms improper input sanitization and exposes whether user-supplied fields directly influence database queries. The result often returns all records, indicating successful injection.

Passive reconnaissance focuses on collecting intelligence without interacting with the target ' s systems. CEH materials emphasize reviewing publicly available information, including leaked documents, breach data, reports, or exposed metadata, as this yields internal network structure details while generating no detectable traffic. This method avoids triggering monitoring systems and aligns with stealth requirements for covert intelligence gathering.
