Your iPhone Duo Under Attack? Binance Flags Dangerous iOS Security Flaw

Brief

By Dextape Desk · November 10, 2026

Binance has cautioned iPhone owners about an iOS flaw called worse_query, which it says could let hostile apps read files that other applications keep isolated. According to the exchange, exposed material might include seed phrases, private keys and login credentials. Binance places the weakness in iOS itself, not its wallet infrastructure. It advises deleting untrusted programs, including manually signed IPA files, and installing the latest official release. Anyone who suspects compromise should build new wallets on clean devices and move funds. Apple's advisories do not explicitly name worse_query, and no confirmed statement shows recent updates fix it. A separate GitHub project said on November 8 that Apple's current releases were still unpatched. Binance also flagged FomoPeek in September, a third-party app reportedly carrying harmful code in versions 1.1 and 1.2.

Why it matters: Wallet recovery phrases and private keys kept on a phone could be reachable by other apps, which bears on how crypto holders protect their funds.
