Two U.S. lawmakers think the government has a new cybersecurity problem: The Internet of Things

When hackers took aim at the internet’s backbone last year, impeding access to websites like Twitter and Spotify, they did so by weaponizing the Internet of Things — a catch-all category of web-connected devices that includes fitness trackers and smart thermostats.

The resulting denial-of-service attack was limited and short-lived, in the end, but cybersecurity fears about IoT remain prevalent — and a group of lawmakers in Congress is now getting to work to ensure the U.S. government raises its own digital defenses in response.
