An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device. That’s when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn’t consented to. The user, Harishankar, decided to block the telemetry servers’ IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after. After a lengthy investigation, he discovered that a remote kill command had been issued to his device.
Certainly. By default most home networks block incoming traffic but then again if the’s the tinkerer type his network will most likely not be default.
This is something I’ve never understood about firewalls. If the vacuum cleaner is uploading and downloading stuff from https://somecorpo.net/, what stops it from listening for remote commands on that same connwction?
