Let’s explore IoT Seeker, a tool designed to help identify and assess Internet of Things (IoT) devices on a network.

🌐 What Is IoT Seeker?

IoT Seeker is a reconnaissance tool used to discover IoT devices on a local or remote network and identify potential security risks. It was developed to assist penetration testers and security analysts in mapping out IoT assets during an engagement.

• Focuses on unauthenticated device discovery
• Identifies devices based on banner grabbing, MAC address, and service fingerprinting
• Helps detect default credentials, open ports, and vulnerable services

🛠️ What Does IoT Seeker Do?

IoT Seeker performs several key functions:

1. Device Discovery

• Scans the network for active hosts
• Uses protocols like HTTP, Telnet, SSH, UPnP, and SNMP to identify IoT devices

2. Fingerprinting

• Matches known patterns to identify device type, vendor, and model
• Uses MAC address OUI lookup and service banners

3. Vulnerability Detection

• Flags devices with default credentials, outdated firmware, or exposed services
• Can integrate with vulnerability databases for CVE matching

🧪 How It Works (Typical Workflow)

1. Network Scan:

   iot-seeker --scan 192.168.1.0/24
   

2. Fingerprinting:
   • Extracts banners from open ports
   • Matches against known IoT device signatures
3. Reporting:
   • Generates a list of discovered devices with vendor info, IP, MAC, and potential vulnerabilities

🔍 What Kind of Devices Can It Find?

• Smart TVs
• IP cameras
• Smart thermostats
• Routers and access points
• Smart plugs and lights
• Industrial IoT sensors

⚠️ Security Implications

IoT Seeker is valuable for:

• Red team operations: Finding weak entry points via insecure IoT devices
• Blue team defense: Monitoring and hardening IoT assets
• Compliance audits: Ensuring devices aren’t using default credentials or outdated firmware

But it also highlights how IoT devices can be a major attack surface if not properly secured.
