IoT security risks
The number of smart devices has exploded, but there is insufficient investment in security. Common risks: default password, firmware not updated, open ports, data leakage. The Mirai botnet is composed of IoT devices.
Common attack paths
Violent cracking of weak passwords → implantation of malicious firmware → joining a botnet → initiating DDoS attacks. Many cameras are live streamed to the public network in real time, seriously violating privacy.
Family protective measures
Change the default password to a strong password, disable UPnP, disable WPS, regularly update firmware, isolate IoT devices to a separate network segment, and disable unnecessary cloud services.
Router reinforcement
Change backend password, disable remote management, use WPA3 encryption, modify default SSID, enable firewall, and restart regularly.
