iOS 18.3.1 Closes Specific Security Gaps
On February 10, Apple released iOS 18.3.1 without prior fanfare. This typically indicates a focus on security updates. A look at the update notes confirms this. It mentions a vulnerability in relation to “USB Restricted Mode.”

Apple states that the measures in iOS 18.3.1 aim to prevent a physical attack vector targeting this feature. The company indicates that this vulnerability could have been exploited to target individuals.
