Apple has detected iPhone spyware attacks against people in more than 150 countries. Knowing if your device is infected can be tricky—but there are a few steps you can take to protect yourself.

The urgent update plugs a hole in the iMessage software that allowed hackers to infiltrate a user's phone, according to Citizen Lab.

The mobile security company said it detected Pegasus spyware attacks on seven iPhone owners, including government officials and a business leader.
