Which tools are used to gather information about target IoT devices, such as manufacturer details and open ports?

• A. Startpage, MetaGer, and eTools.ch
• B. Shodan, Censys, and Thingful
• C. Google Image Search
• D. YouTube DataViewer

Answer: (B)

Information gathering for IoT targets focuses on identifying internet‑exposed devices, learning who made them, and discovering which services and ports are open. Tools like Shodan, Censys, and Thingful are built for this exact purpose. Shodan scans the internet and catalogs devices by the services they expose and the banners they present, which often reveals manufacturer hints and open ports across hosts. Censys uses similar methods, collecting protocol banners and TLS certificates to classify devices and services, giving you visibility into what ports are open and what software is running. Thingful concentrates on IoT specifically, aggregating data about IoT sensors and devices, including vendor, device type, and sometimes location, to map IoT ecosystems. Together, these tools provide a practical way to fingerprint target IoT assets and assess potential entry points. In contrast, general search engines or media-focused tools don’t offer the same systematic IoT device discovery and port information.
