Check Point researchers discovered a security vulnerability in LG SmartThinQ smart home devices that allowed them to hijack internet-connected devices. The vulnerability resides in the mobile app and cloud application used to control LG’s SmartThinkQ home appliances. Hackers could even remotely take control of LG’s Hom-Bot, a camera-equipped robotic vacuum cleaner, and access the live video feed to spy on anything in the device’s vicinity. This hack doesn’t even require hacker and targeted device to be on the same network.
