Q11Internet of Things
Question
Discuss the security and privacy issues in IoT.
Answer
A critical analysis of catastrophic Security and Privacy issues in IoT. Violently details the horrific physical vulnerabilities of botnet hijacking, plaintext data sniffing, and the lack of mathematical hardware encryption on microscopic edge nodes.
The Internet of Things is a security nightmare. Unlike massive cloud servers possessing Terabytes of RAM to execute complex AES-256 cryptographic mathematics, a $2 smart lightbulb possesses an 8-bit microcontroller with 2KB of RAM. It physically cannot run standard security protocols, opening up apocalyptic attack vectors.
1. Massive Botnet Hijacking
IoT devices are shipped with hardcoded, unchangeable default passwords (e.g., admin/admin). Hackers execute automated scripts to scan the public internet for Port 23 (Telnet). They violently log into 500,000 security cameras worldwide, mathematically binding them into a massive Botnet (like Mirai). The hacker then commands these cameras to launch a 1-Terabit-per-second DDoS attack, completely annihilating major internet infrastructure (like Dyn DNS).
2. Eavesdropping and Data Privacy
Because the microscopic sensors cannot execute TLS encryption, they blast their data across Wi-Fi or Zigbee in raw plaintext. An attacker parked in a car outside a hospital can use a $20 antenna to violently sniff the unencrypted pacemaker telemetry data floating through the air, violating absolute medical privacy laws.
3. Physical Tampering and Node Capture
IoT sensors are physically deployed in the wild (e.g., a smart parking meter). A hacker can physically rip the meter open, connect a USB cable directly to the JTAG debugging port on the motherboard, and mathematically dump the entire firmware memory, instantly stealing the corporate Wi-Fi passwords and cryptographic keys hardcoded inside.
