Apple has issued a software patch to block so-called “zero-click” spyware that could infect iPhones and iPads.
Independent researchers identified the flaw, which lets hackers access devices through the iMessage service even if users do not click on a link or file.
The problem affects all of the technology giant’s operating systems, the researchers said.
Apple said it issued the security update in response to a “maliciously crafted” PDF file.
The researchers said that the previously unknown vulnerability affected all major Apple devices, including iPhones, Macs and Apple Watches.
University of Toronto Citizen Lab also said the security issue was exploited to plant spyware on a Saudi activist’s iPhone, adding that it had high confidence that the Israeli hacker-for-hire firm, NSO Group, was behind that attack.
In a statement to the Reuters news agency, NSO did not confirm or deny that it was behind the spyware, saying only that it would “continue to provide intelligence and law enforcement agencies around the world with life-saving technologies to fight terror and crime”.
Security experts have said that although the discovery is significant, most users of Apple devices should not be overly concerned as such attacks are usually highly targeted.
Apple said in a blog post that it had issued the iOS 14.8 and iPadOS 14.8 software patches after it became aware of a report that the flaw “may have been actively exploited”.
The announcement came as the technology giant prepared to unveil new devices at its annual launch event on Tuesday.
The company is expected to reveal new iPhones and updates to its AirPods and Apple Watch.
