Binance issues urgent warning to iPhone users

Cryptocurrency exchange Binance warned iPhone users about a security vulnerability detected in the operating system.

The company stated that the vulnerability covers iOS versions 26.7.1, 27.0.1, and 27.2. All mentioned versions are older Apple operating system updates.

The vulnerability allows a malicious application to directly access local files belonging to other applications on the device. Through this access, recovery phrases, private keys, and account login details of crypto wallets can be compromised.

Risk covers the entire crypto ecosystem

Binance stated that the issue does not originate from the exchange's own infrastructure, but occurs directly at the operating system level. The statement noted that the risk affects the entire cryptocurrency ecosystem, including wallets and other applications storing sensitive data.

The vulnerability was published on GitHub as a proof of concept (PoC) for developers by a security researcher named forcequitOS. According to data provided by the researcher, the flaw affects versions between iOS 26.0 and 26.7.2, as well as iOS 27.2. At this stage, there are no confirmed cases of cryptocurrency theft resulting from the exploitation of this vulnerability.

Steps users should take

Binance recommended the following steps to ensure user security:

• Immediately deleting profiles and applications installed from outside the official App Store,
• Updating the operating system and all applications on the phone to the latest official version,
• Creating a new wallet from scratch on a clean device, transferring assets there, and resetting active sessions for anyone suspecting their data was compromised.

Update step from Apple

Apple released the iOS 27.2.1 update on Monday, one day after the proof of concept was shared on GitHub. While the security notes published by the company listed nine different security vulnerabilities, there was no direct mention of the file access problem in question. Apple has not officially confirmed that this version patches the flaw.

In contrast, the chief information security officer of blockchain security firm SlowMist advised users to install iOS 27.2.1. The SlowMist executive stated that this newly released update will prevent the vulnerability.
