Chris Rouland, CEO of Phosphorus Cybersecurity, shows the ABC7 I-Team a hard drive and info on it, which he said contains billions of usernames and passwords, on the dark web.

Rouland found our producer’s password by entering her email. He said he didn’t buy the information and would never sell it.

“I found it because that’s where I hang out. Because I keep an eye on the bad guys. I heard about a big password breach. Your identity is a commodity. Your identity is valuable. It could be worth $1. It could be worth $1,000. It’s worth something and it’s bought and sold and traded,” he explained.
