Apple issued emergency software updates for a critical vulnerability in its products on Monday after security researchers uncovered a flaw that allows highly invasive spyware from Israel’s NSO Group to infect anyone’s iPhone, iPad, Apple Watch or Mac computer without so much as a click.

Apple’s security team had worked around the clock to develop a fix since Tuesday, after researchers at Citizen Lab, a cybersecurity watchdog organization at the University of Toronto, discovered that a Saudi activist’s iPhone had been infected with an advanced form of spyware from NSO.

You’ve no doubt seen the update (unless you are running a beta, even an iOS 14.7 beta).

Here’s a link to Apple’s official security updates page. Note the new updates that dropped yesterday, including those for Safari, Catalina, Big Sur, Apple Watch, and iOS and iPad OS.
