Binance has warned Apple users about a dangerous iOS vulnerability that could expose crypto wallets, private keys, and login credentials. The flaw, called worse_query, allows malicious applications to access files normally isolated inside other apps. Binance warning identifies several affected iOS software versions and urges users to remove untrusted applications immediately.

The vulnerability threatens more than crypto wallets; apps storing sensitive information locally could also expose passwords, authentication data, and personal files. That makes the latest warning particularly concerning for iPhone users who rely on their devices for banking and crypto transactions.
