  • Apple has urged users to update their iOS devices as soon as possible
  • This will protect your iPhone from web attacks and vulnerabilities
  • Devices running iOS 15 to iOS 26 are already protected

Apple has issued a rare public warning, stating that if you’re running an old version of iOS, you should update your device in order to “protect your iPhone from web attacks.”

The notice has been published in a new security document on Apple’s website. While the company frequently releases security updates and patches to keep customers’ devices secure, it’s unusual for Apple to issue a public call in this manner, which underscores the seriousness of the situation.

In the support document, Apple said that “Security researchers recently identified web-based attacks that target out-of-date versions of iOS through malicious web content. For example, if you’re using an older version of iOS and were to click a malicious link or visit a compromised website, the data on your iPhone might be at risk of being stolen.”

It comes shortly after Google published details of an iOS exploit it had discovered named DarkSword, which is being used by both commercial spyware makers and state-sponsored hackers in the wild.

As for Apple’s warning, the firm added that after being made aware of the hack, it “released software updates as quickly as possible for the most recent operating system versions to address vulnerabilities and disrupt such attacks.” That means that if your iPhone is running iOS 15 through iOS 26, you’re already protected because Apple’s security updates have addressed the vulnerabilities in question.

However, if you have an older version of iOS on your device, you should update it as soon as possible in order to get the security patches and keep this exploit at bay.
