Binance Warns iPhone Users of iOS Flaw That Can Expose Crypto Wallet Keys and Seed Phrases

Binance has issued an urgent security advisory warning iPhone users that an iOS vulnerability, identified as "worse_query," could allow malicious apps to read local files belonging to other apps, exposing crypto wallet seed phrases, private keys, and login credentials. The exchange described the threat as "an iOS-level issue, not unique to Binance," warning that the flaw puts sensitive data "at risk across the entire ecosystem."

The affected iOS versions include 26.7.1, 27.0.1 and 27.2. Apple released iOS 27.2.1 and 26.7.3 on Monday, November 10, but it remains unclear whether either update actually patches the "worse_query" flaw.

Binance urged users to delete any apps installed from untrusted sources, update iOS and all installed apps to the latest official versions, and, if a compromise is suspected, transfer funds to new wallets created on a clean device.
