3What iOS users should do

Anyone using an affected version of iOS has been advised to install the latest operating system update as soon as possible. Binance also recommended creating an entirely new crypto wallet if there’s reason to believe a device may have already been compromised.

Binance said the ‘worse_query’ vulnerability had been identified on devices running iOS 26.7.1, iOS 27.0.1 and iOS 27.2. The security issue could be much more widespread, potentially impacting almost every release of iOS 26, from version 26.0 through to 26.7.2.

An infected app could potentially access sensitive information held by other applications on the same iPhone, including private messages, photographs, documents and saved login details.
Cybercriminals could reportedly use the loophole to secretly view, copy, or even tamper with files belonging to other apps, with cryptocurrency wallets among the potential targets.
