Groups have been targeting phones from around the world with most of the hacks being reported in Australia and some in North America.
Apple has said the issue wasn't with a hack of their iCloud system, but hackers using a phishing email sent to users getting them to put in their account information.
Once they get it the hackers use the "Find my iPhone" program to lock peoples phones and demand money to unlock it. This is known as holding the device for ransom.
Security experts say having a password on your phone in the first place, and making sure you change your Apple user password should be enough to keep you safe.
Even if you don't have an iPhone it's very important to protect your device. Vernon Rood, owner of Idaho Cellular and Repair, says don't open attachments unless you know the person.
"Any hacker gets into the phone through an email or a text message," said Rood. "The best way to protect yourself is especially don't download any text messages that have an attachment to it."
Rood also notes most of the phones that come into their repair shop don't have a password protecting it. He said that's the first step to keeping your information safe.
Especially since it's so easy to access if your phone is lost or stolen.
