Some cybersecurity experts think hackers may have obtained private celebrity images by exploiting weaknesses in an online image-storing platform known as “the cloud.”

“In today’s world everything has changed,” says Aric Bandy, president of a Minneapolis company called Agosto that develops apps for businesses using Google’s cloud.

While cloud technology has huge benefits, Bandy says not all clouds are created equal.

“You absolutely have to look at who it is you’re putting your data with. If it’s Google, if it’s Apple’s iCloud, if it’s Microsoft,” says Bandy. “You can’t just trust that since it’s the cloud, it’s safe.”
