Which project authored a presentation on port scanning using this technique?

• A. HackerStorm
• B. Hashcat
• C. GoogleDiggity
• D. OSVDB

Answer: (C)

Recognizing who authored a presentation on port scanning using this technique hinges on knowing which project focuses on Google-based reconnaissance and information gathering. GoogleDiggity is the project known for exploring how search engine data and publicly available information can reveal exposed hosts and services, including demonstrations of port scanning using those techniques. This makes it the best fit as the presenter of a talk on port scanning with this approach. The other options come from domains such as password cracking, vulnerability databases, or security events, which don’t align with presenting port-scanning methods in this context.
