Binance Warns iOS Flaw Could Put Mobile Wallet Keys at Risk

Binance has warned iPhone users about a vulnerability named worse_query that could expose sensitive crypto-wallet information. According to Crypto Economy, the issue affects iOS 26.7.1, 27.0.1 and 27.2 and could allow malicious applications to read local files belonging to other applications. The exchange said seed phrases, private keys and login information could consequently be exposed.

The warning is not limited to Binance accounts or a particular wallet product. Crypto Economy characterized worse_query as an iOS-level problem, while Crypto.news said the vulnerability could expose crypto wallet keys and recovery phrases. CryptoNews likewise identified seed phrases, private keys and login credentials as potential targets, showing that the reported risk extends across the mobile wallet ecosystem.

Five outlets covered the warning, with their reports broadly aligning on the name of the vulnerability, its file-access mechanism and the potential danger to wallet credentials. Their additional details differ: Crypto Economy supplied the three affected iOS versions, Cointelegraph focused on the advice to remove apps from untrusted sources, and Decrypt focused on the absence of an Apple confirmation. No outlet cited in the supplied coverage reports a conflicting set of affected versions or contradicts Binance’s warning.

Binance’s recommended response was to remove untrusted applications and update the affected software, according to Crypto Economy and Crypto.news. Cointelegraph also reported the removal guidance but said it remained unclear whether Apple’s latest iOS updates fix the vulnerability. Decrypt noted that Apple had not publicly acknowledged the worse_query bug and that a researcher published the finding days before Apple’s latest iOS security update.

The warning did not concern a specifically named cryptocurrency, and the available market data show a broadly weaker backdrop rather than a direct reaction to the security report. Total crypto market capitalization stood at $2.5 trillion, Bitcoin was down 2.70% over 24 hours, and the Fear and Greed Index registered 32, classified as Fear. The market figures provide context but do not establish that the iOS disclosure caused those moves.

The development matters because compromised seed phrases, private keys or login details could affect wallets regardless of which app generated the vulnerable local files. The unresolved questions are whether Apple has addressed the reported weakness, whether the latest updates eliminate the file-access path, and whether affected users need to take additional steps after removing untrusted apps. Apple’s confirmation and the status of a reliable fix are the principal developments to monitor.
