Hackers are increasingly targeting "internet of things" devices to access corporate systems, using things like CCTV cameras or air-conditioning units, according to the CEO of a cybersecurity firm.
The internet of things refers to devices hooked up to the internet, and it has expanded to include everything from household appliances to widgets in power plants.
Nicole Eagan, the CEO of Darktrace, told the WSJ CEO Council Conference in London on Thursday: "There's a lot of internet-of-things devices, everything from thermostats, refrigeration systems, HVAC systems, to people who bring in their Alexa devices into the offices. There's just a lot of IoT. It expands the attack surface, and most of this isn't covered by traditional defenses."
"The attackers used the connected thermometer to get a foothold in the network," she said. "They then found the high-roller database and then pulled that back across the network, out the thermostat, and up to the cloud."
