Apple has released updates to security settings for iPhone, iPad and Watch. They will help protect devices in the event of a hacker attack.

The update is aimed at addressing a security vulnerability in an active hacker attack. Apple said that security researchers from Google Project Zero discovered a vulnerability that could be actively exploited by hackers. The bug was found in WebKit, the browser engine that supports Safari on all Apple devices.

This is the third release of a security update that Apple released in 2021, TechCrunch notes .

A security update is available for iOS 14.4.2 and iPadOS 14.4.2, which also includes older devices like iOS 12.5.2. WatchOS can be updated to version 7.3.3.

It is now unknown who exactly exploited the vulnerabilities or who could have suffered from hacker attacks. Apple did not say whether the attack targeted a small group of users or a broader group.
