( Gizmodo, which got an early look at the tool, describes it as “incredibly easy to install and use”.) Whereas the researchers say their web app doesn’t require any special hardware or complicated set-up so it sounds easier than trying to go packet sniffing your devices yourself. But the level of technical expertise required makes them difficult for plenty of consumers. There are other ways to track devices like this - such as setting up a wireless hotspot to sniff IoT traffic using a packet analyzer like WireShark. Testing the IoT Inspector tool in their lab the researchers say they found a Chromecast device constantly contacting Google’s servers even when not in active use.Ī Geeni smart bulb was also found to be constantly communicating with the cloud - sending/receiving traffic via a URL () that’s operated by a China-based company with a platform which controls IoT devices. (Or indeed how much snitching their gadgets are doing.) The basic idea is to help people see whether devices such as smart speakers or wi-fi enabled robot vacuum cleaners are sharing their data with third parties. In a blog about the effort the researchers write that their aim is to offer a simple tool for consumers to analyze the network traffic of their Internet connected gizmos.
(Currently it’s Mac OS only, with a wait list for Windows or Linux.) The open source tool, called IoT Inspector, is available for download here. Researchers at Princeton University have built a web app that lets you (and them) spy on your smart home devices to see what they’re up to.
