Apple iOS Vulnerability Puts Crypto Wallets at Risk as Binance Issues Warning

Key Takeaways

• Binance warns that worse_query could allow malicious iOS apps to access sensitive files belonging to other applications.
• The vulnerability affects multiple iOS versions, although no confirmed cryptocurrency theft has been attributed to the exploit.
• Apple’s latest updates may block the technique, but the company has not explicitly confirmed a worse_query fix.

Binance Warns iPhone Users of Cross-App Data Exposure

Another security warning has rattled the cryptocurrency industry, this time involving a reported weakness in Apple’s iOS operating system that could compromise sensitive wallet information. On Nov. 10, Binance alerted users to the vulnerability through its official X account, identifying several affected software versions and recommending immediate precautions.

The exchange stated:

“A vulnerability (worse_query) affecting iOS 26.7.1, 27.0.1, and 27.2 allows malicious apps to read local files from other apps, putting seed phrases, private keys, and login credentials at risk across the entire ecosystem. This is an iOS-level issue, not unique to Binance.”

The distinction matters. Unlike an exchange-specific security breach, worse_query concerns the isolation mechanisms designed to prevent applications from accessing one another’s private files. A successful exploit could expose locally stored cryptocurrency recovery information, potentially allowing attackers to compromise wallets if the stolen material provides sufficient access.
