![]() ![]() It said it was aware that the issue may have been exploited and cited Citizen Lab. In a blog post, Apple said it was issuing a security update for iPhones and iPads because a maliciously crafted PDF file could lead to them being hacked. NSO Group did not immediately respond to an email seeking comment. He said the malicious file causes devices to crash. It was discovered during a second examination of the phone, which forensics showed had been infected in March. Malicious image files were transmitted to the activist's phone via the iMessage instant-messaging app before it was hacked with NSO's Pegasus spyware, which opens a phone to eavesdropping and remote data theft, Marczak said. Security experts say that average iPhone, iPad and Mac users generally don't need to worry because such attacks are highly targeted, however, the discovery still alarmed security professionals.

Toronto-based Citizen Lab first identified the security flaw earlier this month and flagged it to Apple. ![]() We're not necessarily attributing this attack to the Saudi government, said researcher Bill Marczak. They said they had high confidence the Israeli company NSO Group was behind the attack, adding that the targeted activist asked to remain anonymous. It was the first time a so-called zero-click exploit had been caught and analyzed, said the researchers, who found the malicious code on Tuesday and immediately alerted Apple. The flaw affected all Apple's operating systems, the researchers said. The researchers at the University of Toronto's Citizen Lab said the flaw allowed spyware from the world's most infamous hacker-for-hire firm, NSO Group, to directly infect the iPhone of a Saudi activist.
