Which Tool Scans IoT Devices for Default Credentials?
John, a professional hacker, targeted CyberSol Inc., an MNC. He decided to discover the IoT devices connected in the target network that are using default credentials and are vulnerable to various hijacking attacks. For this purpose, he used an automated tool to scan the target network for specific types of IoT devices and detect whether they are using the default, factory-set credentials. What is the tool employed by John in the above scenario?

Community Insight
The question tests recognition of purpose-built IoT default-credential scanners, and the trap is choosing a generic IoT traffic analyzer or a cloud/telecom IoT management platform instead of the dedicated scanning tool.
This CEH scenario asks which automated tool scans a target network for IoT devices that still run factory-set default credentials. The correct tool is IoTSeeker, a purpose-built scanner that fingerprints IoT devices and flags default login credentials that enable hijacking.
Learners most often pick A, IoT Inspector, because its name sounds like a network scanner; however, IoT Inspector analyzes live traffic from already-identified IoT devices rather than probing a network for devices that still use factory default credentials.

Expert Analysis
Why the Answer Is Correct
IoTSeeker is an automated scanner specifically written to discover IoT devices on a target network and test whether they still authenticate with default, factory-set credentials — exactly the behaviour described in John's scenario. Devices left on vendor-default usernames and passwords are trivially hijackable, which is why IoTSeeker also reports exposure to those hijacking attacks. As insaniunt noted, the tool is "specifically designed for searching and detecting IoT devices in a network that are using default credentials." This maps directly to the CEH IoT Hacking objective (M18), where default-credential discovery is a core reconnaissance step.Why the Other Options Are Wrong
A, IoT Inspector, is a passive traffic-analysis utility that inspects what an already-located IoT device is communicating, not a scanner that hunts for default credentials across a network. B, AT&T IoT Platform, and D, Azure IoT Central, are commercial IoT connectivity, management and analytics platforms used by defenders and device makers; they provision, monitor and manage fleets rather than attack-scan them for weak logins. As kinaJ put it, AT&T IoT Platform and Azure IoT Central are "IoT management and analytics platforms, but they are not specifically designed for scanning networks." Choosing any of them confuses a defensive/management product with an offensive discovery tool.Community Comment Notes
The community was unanimous, with every recorded vote for C and no dissenting picks, and insaniunt's explanation of IoTSeeker's purpose matches the tool's real function. kinaJ correctly separates IoT Inspector as traffic analysis and rules out the two vendor platforms, which is the distinction most examinees miss. LordXander's terse note, "CEHv12- 2844", simply points back to the question bank item without adding reasoning, while nosavotor asked "Hey friends can we make sure this is correct" — the consensus that answered them is correct.Exam Strategy
When a question names both an automated scanning scenario and default credentials, treat it as a tool-identification drill: eliminate defensive or management platforms first, then pick the tool whose sole documented purpose matches the stated action. In CEH IoT questions, IoTSeeker is the default-credential scanner and IoT Inspector is the traffic analyzer.
Frequently Asked Questions
Why is IoT Inspector not the answer when it also deals with IoT devices?
IoT Inspector passively analyses traffic from devices you already have, whereas the scenario requires actively scanning a network to find devices still using factory default credentials.
Why are AT&T IoT Platform and Azure IoT Central wrong choices?
Both are vendor platforms for provisioning, managing and analysing IoT fleets, not security scanners, so neither can detect default-credential devices during a hack.
