IoT Hacking — Smart Devices Are Not So Smart

IoT Hacking — Your Smart Home is Vulnerable

By 2026, there are 75+ billion IoT devices connected to the internet. Most have terrible security.

Common IoT Vulnerabilities

• 🔴 Default Passwords: admin/admin, root/root, admin/1234
• 🔴 No Encryption: Data sent in plaintext
• 🔴 No Updates: Firmware never patched
• 🔴 Exposed Ports: Telnet, SSH open to internet
• 🔴 Hardcoded Credentials: Can't be changed

Finding IoT Devices

# Shodan — Search engine for IoT
shodan search "webcam" country:IN

# Nmap — Find IoT on local network
nmap -sV --script=banner 192.168.1.0/24

Attacking IP Cameras

# Many cameras use RTSP
nmap -sV -p 554 192.168.1.0/24
# Access stream: rtsp://camera_ip:554/live.sdp
# Try default credentials: admin/admin, admin/12345

Attacking Smart Home Devices

• Smart Bulbs: Can leak WiFi credentials
• Smart TVs: Can be turned into surveillance devices
• Voice Assistants: Ultrasonic command injection
• Smart Locks: Bluetooth replay attacks
• Baby Monitors: Often accessible with default creds

IoT Botnets

The Mirai botnet infected 600,000 IoT devices and launched a 1.2 Tbps DDoS attack that took down Twitter, Netflix, and Reddit in 2016.

Protection

• Change all default passwords immediately
• Put IoT devices on a separate network
• Disable unused features (Telnet, UPnP)
• Regular firmware updates
