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 hij

IoT Inspector is typically a security monitoring and visibility tool for IoT devices, often found in enterprise or home network security solutions, rather than an active scanning tool specifically for detecting default credentials in a penetration testing context.

AT&T IoT Platform is a commercial service for connecting, managing, and securing IoT devices at a platform level, not a network scanning tool for discovering vulnerabilities or default credentials.

IoTSeeker is a known open-source tool specifically designed for scanning networks to discover Internet of Things (IoT) devices and identify common vulnerabilities, including the use of default, factory-set credentials. Its functionality directly matches the scenario of a hacker automating the detection of vulnerable IoT devices with weak authentication.

Azure IoT Central is a cloud-based application platform for building and managing IoT solutions, focusing on device connectivity, data ingestion, and application logic, not a network reconnaissance or vulnerability scanning tool.
