Binance Warns iPhone Users of iOS Security Flaw
The exchange says malicious apps could reach other apps’ private files, including crypto wallet recovery phrases and login credentials, and urges users to update iOS.
Binance warns an iOS flaw could let malicious apps reach crypto wallet data on iPhones. It advises updating iOS and avoiding untrusted apps.
Crypto exchange Binance has warned iPhone users about a security vulnerability in Apple’s iOS that could expose cryptocurrency credentials. The alert was issued on Tuesday, November 10. Binance said the flaw is in iOS and not in its own app.
What the Flaw Could Allow
The vulnerability, reportedly called “worse_query,” could let malicious apps reach other apps’ private files, including crypto wallet recovery phrases, private keys and login credentials. BleepingComputer describes it as a “sandbox escape.” The affected versions are reported as iOS 26.7.1, 27.0.1 and 27.2. An attacker would first need to get a victim to install a malicious app, possibly from an unofficial or untrusted source.
Apple’s Updates
Apple released iOS 27.2.1 and iOS 26.7.3 on November 9 to fix several security issues. One patch, CVE-2026-113963, addresses a flaw that could let an app access sensitive user information. It is not yet confirmed whether these updates fix “worse_query.”
Binance’s Advice
Install the latest iOS security updates and keep apps updated.
Review installed apps and remove any that are unneeded or untrusted.
Avoid apps from unofficial sources, especially those outside the App Store.
If a wallet may be exposed, move assets to a new wallet created on a clean, trusted device.
Reset active login sessions to block unauthorised access.
