Apple has issued emergency security updates to patch a zero-day vulnerability that was exploited in targeted and "extremely sophisticated" attacks.
USB Restricted Mode Bypass Exploit
According to Apple's advisory, the vulnerability allows a physical attack to disable USB Restricted Mode on a locked iPhone or iPad.
"Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals."
USB Restricted Mode, introduced in iOS 11.4.1 nearly seven years ago, prevents USB accessories from establishing a data connection if the device has been locked for over an hour. This security measure is designed to block forensic tools like GrayKey and Cellebrite, often used by law enforcement, from extracting data from locked iOS devices.
New Security Feature: Inactivity Reboot
In November, Apple added another security feature called "inactivity reboot" to further protect user data. This feature automatically restarts iPhones after extended idle periods, re-encrypting data and making it more difficult for forensic tools to extract information.
Details of the Zero-Day Vulnerability
The newly patched vulnerability, tracked as CVE-2025-24200, is an authorization issue discovered by Citizen Lab's Bill Marczak. Apple has addressed this flaw in the latest updates:
iOS 18.3.1
iPadOS 18.3.1
iPadOS 17.7.5
The fix involves improved state management to prevent unauthorized access.
Affected Apple Devices
The vulnerability impacts a wide range of Apple devices, including:
iPhones:
iPhone XS and later
iPads:
iPad Pro 13-inch, iPad Pro 12.9-inch (3rd gen and later), iPad Pro 11-inch (1st gen and later)
iPad Air (3rd gen and later), iPad (7th gen and later), iPad mini (5th gen and later)
iPad Pro 12.9-inch (2nd gen), iPad Pro 10.5-inch, iPad (6th gen)
Urgent Recommendation: Update Immediately
Although this vulnerability was exploited only in targeted attacks, Apple strongly advises all users to install the latest security updates immediately to prevent potential exploitation.
While Apple has not yet disclosed specific details about in-the-wild attacks, Citizen Lab researchers have previously uncovered zero-days used in spyware attacks against high-risk individuals, including journalists, opposition politicians, and dissidents.
Updating your device ensures protection against this and other potential threats.
