Google Hacking, also known as Google Dorking, is a passive reconnaissance technique covered in CEH v13 Reconnaissance Techniques. It involves using advanced search operators to uncover sensitive information that has been inadvertently indexed by search engines.
CEH v13 explains that Google Hacking can reveal exposed files, directories, configuration files, backups, login portals, error messages, and sensitive documents. This information often resides on the Deep Web, meaning it is not easily accessible through normal browsing but is still indexed by search engines.
Option D correctly reflects this capability. Google Hacking does not analyze source code directly (Option A), map internal networks (Option C), or primarily detect phishing sites (Option B), although it may indirectly assist with those tasks.
Because Google Hacking relies solely on publicly available data and does not interact directly with target systems, it fits perfectly within passive footprinting, making it legally and ethically appropriate when authorized.
CEH v13 emphasizes Google Hacking as a powerful method to identify unintended data exposure. Therefore, Option D is the correct justification.
