Хранение сид-фраз на iPhone 11 и более ранних моделях несет риски даже после сброса настроек и включения авиарежима. Эти устройства подвержены атакам через аппаратные уязвимости, которые нельзя устранить обновлением iOS, предупредил основатель производителя аппаратных кошельков OneKey Иши Ван.
Over the past two weeks iPhones have been publicly jailbroken more than once, and most people treated it as a bit of tech drama and scrolled on. I want to use it to talk about something that matters more to people in crypto: wiping an old iPhone, putting it in airplane mode and using it only to hold your seed phrase is not as safe as most people think. If it’s an iPhone 11 or older, the problem lives in the chip, and no iOS update will fix it. Quick recap of what happened. On October 16 at Hexacon in Paris, the Calif team jailbroke an iPhone 18 Pro running iOS 27.0.1 live on stage. The jailbreak survived a reboot, they had root, and they got past MIE, the hardware memory protection Apple added starting with the A19 specifically to stop spyware. In the same session they showed attacks that get in through a single click in Signal or iMessage. A week later, on the day iPhone Duo went on sale, they jailbroke that too. Apple shipped iOS 27.2 on October 26, and Calif says most of the bugs they used are now fixed. Then on October 30, Ikotas Labs, the Japanese team that just won Pwn2Own, posted that they had jailbroken 27.2 as well. Their video only shows swapped icons and the version number, though, so I’m treating it as unconfirmed for now. For most people on a recent phone who keep it updated, none of this is a reason to panic. Before chains like these get patched, they usually sit with spyware vendors and forensics companies, and the odds of an ordinary person being specifically targeted are low. Update to 27.2 and you’ve done what you need to. The people I actually want to warn are those using an old iPhone as a cold wallet. iPhone 4S through iPhone X have checkm8 in the BootROM, made public in 2019. This June, usbliter8 went public, covering the iPhone XS, XR, the 11 series and the 2nd-gen SE. The BootROM is boot code burned into the chip at the factory. Apple can’t patch it with a software update, so these devices will carry the hole for as long as they exist. Exploiting it doesn’t need a network either. Once someone has your phone in hand, they put it into DFU mode and plug in a custom USB board (the public research used a $5 Raspberry Pi Pico 2), and they can run their own code before iOS even boots. Airplane mode makes no difference here. I don’t want to overstate it. On models like the XS and 11, the BootROM bug alone won’t hand over your seed phrase, because your passcode and the Secure Enclave are still in the way. The trouble is that these remaining layers are exactly where people tend to cut corners: a 6-digit passcode, an iOS version years out of date with a pile of public n-days, a short wallet app password. On some older models, forensic tools use bugs like this to brute-force the passcode. And if your wallet app encrypts the seed with nothing but a short password, once that encrypted file is copied off, the attacker can take it home and keep guessing offline, with no attempt limit. Old iOS versions also have a charging port problem. ChoiceJacking, published in 2025, lets a malicious charger pose as a keyboard and approve the>October 31, 2026
Предприниматель напомнил о двух уязвимостях смартфонов от Apple. Раскрытая в 2019 году checkm8 затрагивает поколения iPhone от 4S до X. Обнаруженная в июне 2026 года usbliter8 затрагивает чипы A12 и A13, которые используются в XS, XR, линейке 11 и SE второго поколения.
