According to CoinMeta, Ledger's Chief Technology Officer Charles Guillemet recently warned cryptocurrency holders not to store important wallet information on iPhone due to rising security threats. He pointed out on social media that vulnerabilities that can leak important data are becoming increasingly easy for hackers to exploit. He emphasized, "Do not store anything valuable on your phone, especially your encryption seeds." This warning is in response to an emergency security alert issued by the crypto exchange Binance regarding a vulnerability in Apple's iOS operating system. The vulnerability allows malicious applications to access files of other applications on the same device, affecting versions iOS 26.7.1, 27.0.1, and 27.2. Binance recommends that users uninstall applications from untrusted sources, update their operating systems, and avoid installing any unauthorized software.
