No less than 98 per cent of traffic sent by internet-of-things (IoT) devices is unencrypted, exposing huge quantities of personal and confidential data to potential attackers, fresh analysis has revealed.
What’s more, most networks mix IoT devices with more traditional IT assets like laptops, desktops and mobile devices, exposing those networks to malware from both ends: a vulnerable IoT device can infect PCs; and an unpatched laptop could give an attacker access to IoT devices – and vast quantities of saleable data.
Those are the big conclusions from a real-world test of 1.2 million IoT devices across thousands of physical locations in the United States, carried out by Palo Alto Networks.
