The flaw, disclosed Monday by Citizen Lab, allowed a hacker using NSO’s malware Pegasus to gain access to a device owned by a Saudi activist, according to security researchers.

Apple Inc. said it patched a security flaw in the Messages app after security researchers determined that Israel-based NSO Group used it to “exploit and infect” the latest devices with spyware.The flaw, disclosed Monday by Citizen Lab, allowed a hacker using NSO’s Pegasus malware to gain access to a device owned by an unnamed Saudi activist, according to security researchers. Apple said the flaw could be exploited if a user on a vulnerable device received a “maliciously crafted” PDF file.

The flaw was a “zero-day” vulnerability, a term that refers to recently discovered bugs that hackers can exploit and haven’t yet been patched. Victims didn’t have to click on the malicious file for it to infect their devices, something known as a “zero-click” exploit, according to a report released by Citizen Lab, a cyber-research unit of the University of Toronto.

“What this highlights is that chat apps are the soft underbelly of device security,” said John Scott-Railton, senior researcher at Citizen Lab, in a text message. “They are ubiquitous, which makes them really attractive, so they are an increasingly common target for attackers.

“They need to be a major priority for security,” he added. “Narrowing the attack surface from chat apps will go a long way toward making all of our devices more secure.”

Apple is patching the bug on the iPhone, iPad, Mac, and Apple Watch via iOS 14.8, iPadOS 14.8, macOS 11.6 and watchOS 7.6.2 software updates. The software releases came the day before Apple’s Sept. 14 product launch event, which will likely spur the release of iOS 15, Apple’s next major software update that will contain additional security protections.

“Apple is aware of a report that this issue may have been actively exploited,” the iPhone maker said on its website.

Apple shares were little changed in extended trading after closing at $149.55 in New York.

NSO Group, in a statement, said the company “will continue to provide intelligence and law enforcement agencies around the world with life saving technologies to fight terror and crime.”

The NSO Group has been the subject of repeated criticism by Citizen Lab and other organizations after its spyware has been discovered on the phones of activists and journalists critical of repressive regimes. In its report Monday, Citizen Lab accused NSO Group of facilitating “despotism-as-a-service for unaccountable government security agencies” and argued that regulation is “desperately needed.”

NSO Group has insisted that the spyware is intended to be used to fight terrorism and crime, not to aid in human rights abuses.

In June, the company published its first “Transparency and Responsibility Report,” which defended its technology and efforts to curb misuse by customers.

The White House has raised concerns about NSO Group with senior Israeli officials, the Washington Post reported.

In December, Citizen Lab reported that NSO spyware was used to target the devices of 36 Al Jazeera employees. Citizen Lab said that it believed the hacks were carried out on behalf of Saudi Arabia and the United Arab Emirates. The hack in 2020 is similar to the one disclosed Monday because it didn’t require the victim to click on a malicious link, meaning there is no way to defend from the hack. NSO Group denied the report.
