Your IoT Devices are a Risk

The Consumer Electronics Show in Las Vegas was dominated by more smart devices -- especially smart speakers. As the "Internet of Things" becomes a bigger deal, the worry is hackers will find more ways to monkey with Alexa.

Security expert Don Malloy, from the CES floor, says Blockchain is the answer to security.

"Blockchain, and all the components of authenticating to it, is going to be the foundation for growth."

Tech reporter Michelle Quinn says it's not just speakers, it's smart pillows.

"There may be 20 sensor companies dealing with sleep; pillows that heat up at night and cool down, or heat up to wake you up."

Imagine your pillow getting hacked. Add tractors to the list of stuff that could be hacked someday.

Quinn says one of the biggest exhibits at CES was by John Deere.

"They brought a huge tractor to show CES and the tech community 'we've been doing self-driving tractors for a while; we know how to make a tractor run without anybody using the steering wheel."

What will protect your tractor from hackers? The almost unanimous answer from security experts is Blockchain encryption -- the technology behind Bitcoin.

But most consumers don't seem to care about the security risks to their pillows, tractors or smart speakers.
