While smart home devices enhance the convenience of life, there is also a security risk of being maliciously used. The following are the potential ways and specific scenario analysis that smart devices may be manipulated by robbers to assist in burglaries and robberies.： ###1. Equipment intrusion method 1. **Weak password and default settings** -Case study: In 2021, a security team discovered that the default administrator password of a certain brand of smart door lock was 123456, and hackers could unlock it remotely through brute force cracking. -Data: The Verizon report shows that 63% of data leaks are related to weak or default passwords. 2. **Firmware exploit** -A mainstream camera brand has exposed an unencrypted firmware vulnerability, and an attacker can inject malicious code to turn off the motion detection function. 3. **Man-in-the-middle attack (MITM)** -Hijack the communication between the device and the controller by faking a home WiFi hotspot (such as a "Free_WiFi" trap). ###2. Specific attack scenarios 1. **Breakthrough in access control system** -Tesla coil attack: Wireless interference technology for electronic door locks (requires operation within 3 meters) -Cloud interface vulnerability: A smart lock API vulnerability allows unlocking through forged HTTP requests 2. **Environmental camouflage technology** -Temperature control system: continuously adjust the temperature to induce residents to open windows for ventilation -Lighting simulation: copy the daily lighting patterns of residents to create the illusion of "someone in the house" 3. **The security system is paralyzed** -Camera shielding: Inject instructions to make the device continue to display static pictures -Alarm suppression: disable door and window sensors through Zigbee protocol vulnerability ###3. New composite attack mode 1. **Device linkage vulnerability** Example: Trigger the smart smoke alarm→ linkage to open the window for ventilation→ Unlock the electromagnetic lock of the anti-theft network 2. **Permission hijacking chain** Temporary visitor rights (such as housekeeping services) → Horizontal penetration into the main control system → create a hidden backdoor ###4. Protection recommendations (technical defense-in-depth) 1. Network layer isolation: IoT devices are networked separately and 802.1X authentication is enabled 2. Hardware-level protection: choose a smart door lock with SE security chip 3. Behavior monitoring: Deploy an AI anomaly detection system (such as frequent verification of door locks and alarms at 3 a.m.) 4. Firmware verification: Enable Secure Boot to prevent unsigned updates According to the OWASP IoT Top 10 report, 94% of deployed IOT devices have at least 3 high-risk vulnerabilities. It is recommended that users regularly check equipment security certifications (such as ioXt Alliance ratings) and pay attention to updates to the CVE vulnerability database. Smart home security needs to form a complete closed loop from product purchase, configuration management to continuous monitoring in order to effectively reduce risks.
