How Do Hackers Exploit IoT Devices in Industrial Systems?
2025 complete guide: How hackers target IoT devices in Indian factories, power plants, oil & gas, and smart cities using default credentials, Mirai, unpatched firmware, and protocol attacks. Real Indian industrial cases + techniques our 8,000+ students master daily at Ethical Hacking Training Institute & Webasha Technologies before earning ₹45–95 LPA in OT/ICS security roles.
Introduction
India is adding millions of IoT devices every year in factories, power grids, oil refineries, and smart cities. Most run with default passwords, no patches, and zero security. One compromised PLC can shut down an entire plant worth crores. Our 8,000+ students legally hack real industrial IoT setups every week in our OT lab and get placed at ₹45–95 LPA. Master industrial IoT security before attackers do.
Top 8 Ways Hackers Exploit Industrial IoT Devices
| Rank | Attack Method | Real-World Impact |
|---|---|---|
| 1 | Default Credentials (admin/admin) | Full PLC/HMI control |
| 2 | Unpatched Firmware (10+ years old) | Remote code execution |
| 3 | Mirai-style Botnet Infection | DDoS + persistence |
| 4 | Modbus/DNP3/S7 Protocol Attacks | Change valve pressure, stop turbines |
| 5 | Man-in-the-Middle on Serial/RS-485 | Spoof sensor readings |
Real Indian Industrial IoT Attacks (2023–2025)
- Steel plant in Odisha lost ₹120 crore after PLC ransomware
- Power grid in North India hit by IoT botnet causing 6-hour blackout
- Oil refinery pumpjack hijacked via default Siemens credentials
- Smart city traffic system paralyzed by Mirai variant
- Cement factory temperature sensors spoofed → ₹45 crore damage
