One prime example is the Murdoc botnet,actively exploiting vulnerabilities in AVTECH cameras and Huawei routers. Dr. Sterling emphasizes the responsibility of manufacturers: “Manufacturers need to prioritize security from the outset, not treating it as an afterthought. Robust password protection, secure software updates, and making unauthorized access difficult are crucial. They also have a responsibility to provide firmware updates to patch known vulnerabilities.”

But what can consumers do to protect themselves? Dr. Sterling advises, “Change default passwords, keep firmware updated, and consider using IoT security solutions designed to safeguard your network and devices. Be mindful of the devices you connect and ensure they’re from reputable manufacturers.”

Beyond DDoS attacks, Dr. Sterling warns about the potential for IoT devices to be used in other malicious activities. “We could see ransomware attacks targeting smart homes, data theft, or even physical harm if connected devices are tampered with. Every connected device represents a potential entry point for cybercriminals, reminding us of the urgency of addressing these security concerns.”

Dr. Sterling concludes with a powerful message: “Stay informed and proactive.The cyber threats landscape is constantly evolving, and we all need to do our part. From consumers to manufacturers, everyone plays a role in mitigating these risks.”
