JTBC's YouTube channel Hey.Story recently explored the security vulnerabilities of common IoT devices in modern homes and discussed potential countermeasures. The episode specifically focused on the security aspects of robot vacuums equipped with cameras. Young-min Cho, CEO of ZIEN and former white hat hacker, appeared as an expert guest sharing in-depth insights. Using Roborock's robot vacuum as an example, he explained the importance of IoT security certification, highlighting how it achieved a diamond-grade security rating.
In the video, CEO Cho pointed out that billions of IoT devices are being used worldwide, with many deployed without adequate security measures. He emphasized that household IoT devices are particularly vulnerable to hacking due to their close connection with users. The demonstration included hacking a home camera feed by exploiting weak passwords and account settings. Along with the hacking demonstration, viewers learned valuable information about preventive measures and criteria for selecting secure IoT devices.
Major Hacking Threats
Key security threats include:
Weak passwords and default factory settings
One-day vulnerabilities (known vulnerabilities)
Bluetooth communication vulnerabilities
For issues beyond consumer control, such as zero-day vulnerabilities (unknown vulnerabilities) and network communication hacking, manufacturers must maintain regular updates and security checks.
Checklist for Selecting Secure IoT Devices
CEO Cho recommended checking the following when selecting IoT devices:
Continuous security updates from the manufacturer
Data encryption support
Certified security certifications
User authentication security
International security certification labels
How to Prevent Hacking?
The expert suggests these basic measures to prevent hacking:
Change default passwords: Always modify manufacturer-set default passwords
Software updates: Keep devices updated with the latest software as older versions are easily compromised
Regular security checks: Users should strengthen security through periodic checks and configuration updates
The video emphasized that "there's no such thing as 100% security." Even products with excellent security certifications can become vulnerable to new threats without continuous updates and management. A secure IoT environment can only be achieved when manufacturers maintain consistent security management alongside user awareness. This content provides an opportunity to reflect on the importance of IoT security and our future direction. ZIEN remains committed to creating a safer digital environment.
