Teacher Yu just reminded everyone this morning, and Binance is reminding us again tonight. This is definitely not a minor issue, so everyone must pay attention: ⚠️ Binance warns: The iOS "worse_query" vulnerability could allow malicious apps to read files from other apps. If your mnemonic phrase, private key, or login credentials are in readable files, there is a risk of leakage. Delete side-loaded apps from unknown sources, update your system and wallet software, and do not save your mnemonic phrase on your phone. If you suspect a leak, create a new wallet on a clean device and transfer your assets. A reminder again: Use a hardware wallet to isolate your private keys for large amounts of assets! Using your usual computer and mobile phone is never suitable for large amounts of assets.
