TOPEKA, Kan. (WIBW) The F.B.I and Apple are now investigating a photo hacking case that leaked several revealing celebrity photos on the internet.
Nude photos of "Hunger Games" star Jennifer Lawrence and intimate photos of more than 100 other celebrities were leaked over the weekend by hackers.
The photos were taken from iCloud, an Apple service that stores photos taken by a user's cell phone.
Apple told CBS it was "a very targeted attack on user names passwords and security questions, a practice that has become all too common on the internet."
Now, there is concern about the security of photographs and videos for millions of Americans who use iCloud.
Digital Content Director Nick Viviani says hackers used a brute force attack.
"A brute force attack is when hackers try the same password over and over again until they get it right," said Vivani, "you want to make sure your password isn't the same in your Google account, Facebook, Twitter. Make sure to use a mixture of letters and numbers and make it unique."
That can help everyone personal's information a little more secure.
Another way to protect your personal data is to opt for two-factor authentication.
That's when you log into a website with a password, then the site sends a text message to your cell phone with a unique code to enter that option is already available onsites like Google, Facebook and Twitter.
Viviani says you can also put incorrect answers to your security questions so that hackers won't guess the obvious answers.
