A culture of spreading intimate details online is putting young people at risk of identity theft, the Better Business Bureau says.

Peter Moorhouse, president of the organization in Atlantic Canada, says his group is noticing that more young people are falling victim to this kind of fraud.

"When you think about the questions that we use to protect our passwords and banking information, a lot of that stuff we're putting out on social media without even thinking about it," he said.

Moorhouse says students' clean credit rating make them ripe targets.

They also tend to take their devices everywhere, logging on to free Wi-Fi at the local coffee shop to check email.

Security consultant Andrew Kozma says it's easy for people to harvest usernames and passwords in public places.

"What it comes down to is they trust the coffee shop service and I'm exploiting that trust by making my network highly available — more available than the legitimate coffee shop," Kozma said.

"During that traversal, I capture that information and can use that data later."

He says people can stay safe if they avoid looking at personal information on unfamiliar networks.
