⚠️ALARMING: Using an OLD iPhone as a cold wallet may not be as safe as you think, OneKey founder Yishi Wang warns. Following several public iPhone jailbreak demos over the past two weeks, he highlighted a risk for crypto holders. Wiping the device and enabling airplane mode does not remove chip vulnerabilities affecting iPhone 11 and earlier models, including the second-gen SE. The BootROM flaws cannot be fixed through iOS updates. THE RISKS: - A phone accessed while unattended or borrowed may look normal when returned. This is known as an “evil maid” attack. - An attacker could use specialized USB tools to run code before iOS starts. No internet connection is needed. - Outdated software, short PINs and weak wallet passwords could make an attack easier. If an encrypted wallet file is extracted, attackers could keep guessing its password offline. - Yishi cites ChoiceJacking, a separate technique that can approve data-access prompts on vulnerable older software. Apple addressed it in iOS 18.4. Yishi recommends generating a completely new seed in a trusted environment and transferring funds. A new address under the old seed is not enough. Of note, users with recent, updated iPhones have LESS reason for concern.
