Update your iPhone now to fix a major security flaw

Apple released an emergency fix Monday for a vulnerability in the iPhone, iPad, Mac, and Apple Watch.

Researchers at the University of Toronto's Citizen Lab warned on its blog Tuesday about a "zero-click" exploit. It had been used to infect the phone of a Saudi activist with the help of NSO Group's Pegasus spyware. Apple device users were vulnerable even if they didn't click on anything.

According to the New York Times, Apple worked "around the clock" after the Citizen Lab blog post to fix the problem.

To update your iPhone with iOS version 14.8, go to "Settings," then "General," and then "Software Update." The process to update iPads is similar.

If you need to update your Mac, click the Apple icon in the top left corner of the screen, open up "System Preferences," and then choose "Software Update."

Apple Watch users should update to watchOS 7.6.2. You can do that through the iPhone's Watch app. Or you can update directly on the Apple Watch once you're connected to WiFi. Head to the Settings app, click "General," and then "Software Update."

We reached out to Apple to learn more about the spyware fix, but didn't hear back immediately.
