Binance flags affected iOS versions
Binance warned Tuesday that an iOS flaw could expose crypto wallet recovery phrases and private keys if a user runs a malicious app on an affected iPhone. The exchange listed iOS 26.7.1, 27.0.1 and 27.2 among the versions that could let malicious apps read local files from other apps. That access could put seed phrases, private keys and login credentials at risk across the wider crypto space, Binance said. The company added that the problem is an iOS-level issue and not one unique to Binance.
The warning matters because wallet keys are often stored or handled on the same device people use for everyday apps. A malicious app that can reach another app’s files may not need a sophisticated attack. That is perhaps the most troubling part. Binance did not say how many users might be affected, but it urged caution.
What users should do now
Binance told users to delete any apps installed from untrusted sources. It also advised updating iOS and all apps to the latest official versions. If someone suspects a breach already happened, Binance said they should move funds to new wallets created on clean devices. That last step is important. Creating a new wallet on the same phone may not solve the problem if the device is still compromised. For now, the practical advice is simple: treat unknown apps as a risk, keep devices updated, and consider a clean device for wallet recovery.
Disclosure timeline and patch questions
Blockchain security firm SlowMist flagged the issue earlier on Tuesday. It said a malicious app could read recovery phrases if a wallet stores them unencrypted on the device. An iOS security researcher who goes by forcequitOS publicly disclosed the flaw on Sunday and credited another researcher who goes by 0xjohnny.
Apple released iOS 27.2.1 and 26.7.3 on Monday. It remains unclear whether either update fixes the flaw. Cointelegraph contacted Apple and Binance about the vulnerability but had not received a response by publication.
