Nov 10, 2026 · Summarized by Fundy Tech from 2 sources
The 30-second version
Binance says a published iOS sandbox escape could let apps read other apps’ files, including wallet keys and login details. Apple’s latest updates do not list a fix.
Key points
- The issue affects iOS 26 and 27 versions named by Binance.
- A proof-of-concept app called WQ Files can read other apps’ data.
- No crypto losses have been confirmed, according to Binance.
Why it matters
For households and crypto users, this could expose seed phrases, private keys and login credentials if risky apps are installed. The safest move is to remove untrusted apps and update iOS and all apps. If you suspect compromise, move funds to a new wallet on a clean device.
Who’s affected: iPhones running the affected iOS versions
What to do
- Update iOS and all apps.
- Delete untrusted or sideloaded apps.
- Move funds to a new wallet if you suspect compromise.
