Apple has released an emergency update, iOS 18.3.1, addressing a critical zero-day vulnerability that has been exploited in sophisticated attacks targeting high-risk individuals. This update primarily fixes an issue with USB Restricted Mode, which became vulnerable during physical attacks aimed at locked devices. The flaw, tracked as CVE-2025-24200, was reported by Citizen Lab security researcher Bill Marczak. It's essential for iPhone and iPad users—particularly those who are journalists, activists, or public figures—to update their devices immediately to mitigate ongoing security threats. The update is available to iPhone XS and later, and several iPad Pro models, ensuring users have the most secure version of iOS to fend off these targeted attacks.
