GREEN BAY, Wis. (WFRV) - Most people never leave home without it.

"I'm on my phone a lot," said Jessica Groh.

"I have a lot of pictures on my phone and I normally upload them to Facebook or Instagram and just share them to people," said Brooke Iserloth.

But what about things you want to keep private? Banking information, emails, or personal pictures?

"Personally, if I put something in the cloud," explained Jim Overly, owner of Cyber Works in Green Bay. "I assume it's out there for someone to find whenever, however long it takes."

Overly describes the iCloud back-up service as a series of computers in data centers used to store information. So even if you delete something from your phone or computer, it likely still exists somewhere else.

"Things don't automatically go into the cloud," he said. "Unless your phone is set up that way. You can have it so that every picture you take is automatically backed up in the cloud, which gives you some security that that picture is there for your home computer if you lose your phone. So that's great. The negative is that picture is in the cloud and, in the worst case, someone may gain access to it."

It's still unknown what exactly caused the massive leak of celebrity photos, but experts believe hackers wrote programs to continuously enter passwords until the right ones were found.

"I try to get a really different password that no one can really guess and I try to keep my security settings on high," said Brooke Iserloth.

"I'll use an uppercase letter and I'll use numbers and stuff like that so it's like harder to get access," added Jessica Groh.

Experts also recommend changing passwords every couple of months.
