Apple Fixes Zero-Day Exploited In 'Extremely Sophisticated' Attacks

Apple has released emergency security updates for iOS 18.3.1 and iPadOS 18.3.1 to patch a zero-day vulnerability (CVE-2025-24200) that was exploited in "extremely sophisticated," targeted attacks. The flaw, which allowed a physical attack to disable USB Restricted Mode on locked devices, was discovered by Citizen Lab and may have been used in spyware campaigns; users are strongly advised to install the update immediately. BleepingComputer reports: USB Restricted Mode is a security feature (introduced almost seven years ago in iOS 11.4.1) that blocks USB accessories from creating a data connection if the device has been locked for over an hour. This feature is designed to block forensic software like Graykey and Cellebrite (commonly used by law enforcement) from extracting data from locked iOS devices. In November, Apple introduced another security feature (dubbed "inactivity reboot") that automatically restarts iPhones after long idle times to re-encrypt data and make it harder to extract by forensic software. The zero-day vulnerability (tracked as CVE-2025-24200 and reported by Citizen Lab's Bill Marczak) patched today by Apple is an authorization issue addressed in iOS 18.3.1 and iPadOS 18.3.1 with improved state management. The list of devices this zero-day impacts includes:- iPhone XS and later,- iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and laterRead more of this story at Slashdot.
