Binance has issued a warning about a reported flaw in Apple's iOS that could expose the private keys of iPhone users. The bug, referred to as "worse_query", has not been publicly confirmed by Apple.

A security researcher published details of the issue only days before Apple released its most recent iOS security update. It remains unclear from the available information whether that update addresses the problem, and Apple has not said so.

Why it matters for crypto users

Private keys are the credentials that control access to crypto assets. Anyone who obtains them can move funds without the owner's consent, and such transfers generally cannot be reversed. A flaw that might leak this data from a phone is therefore a serious concern for people who hold digital assets in mobile wallets.

Binance's warning signals that the exchange takes the report seriously enough to alert users, even without a confirmation from Apple. The technical details of how the bug works and how easily it could be exploited have not been verified by the company that makes iOS.

What comes next

The key open question is whether Apple will acknowledge the "worse_query" bug and clarify whether its latest security update covers it. Until then, iPhone owners who store crypto on their devices have reason to follow official guidance from Apple and their wallet providers, and to install available iOS updates.
