About 40 percent of households across the globe now contain at least one IoT device, according to Avast.

In North America, that number is almost double, at 66 percent, bringing with it an associated growth in cybersecurity risks. The findings have been published in a new research paper “All Things Considered: An Analysis of IoT Devices on Home Networks”.

The research is the largest global study to date examining the state of IoT devices. Avast scanned 83 million IoT devices in 16 million homes worldwide to understand the distribution and security profile of IoT devices by type and manufacturer. The findings were then validated and analyzed by research teams at Avast and Stanford University.
