Apple Expands iOS 18.7.7 Update to More Devices to Shield Users from DarkSword Exploit

DarkSword is a sophisticated, web-delivered iOS exploit kit targeting iOS 18.4–18.7 via a six-vulnerability chain (including JavaScriptCore, dyld and sandbox bugs) to achieve kernel-level execution and exfiltrate passwords, messages, location, wallets, and health data. First observed in late 2025 and later used by commercial surveillance vendors and suspected state actors, the toolkit was publicly leaked in March 2026, increasing the risk of widespread abuse; Apple backported fixes in iOS 18.7.7, recommends upgrading to iOS 26.3, and highlights Lockdown Mode for high-risk users.
