Cybersecurity researchers have said they discovered a new iPhone-hacking technique that targets devices running older versions of Apple’s mobile operating system, highlighting the risk of not keeping the software up to date.

Researchers at Google Threat Intelligence Group, along with mobile security firms iVerify and Lookout, published their findings on March 18 describing an exploit framework they call “DarkSword.” The tool was used in attacks delivered through compromised websites and was designed to infect iPhones running iOS 18.4 through 18.7, with some observed campaigns specifically targeting versions 18.4 through 18.6.2.
