iPhone 17 Adds Advanced Memory Security, Protecting Crypto Wallets

Apple’s iPhone 17 introduces Memory Integrity Enforcement (MIE), a hardware‑level safety upgrade that’s on by default and built for high‑risk users like high‑net‑worth crypto holders and frequent signers. MIE pairs with EMTE for real‑time validation, blocking zero‑day chains such as out‑of‑bounds and use‑after‑free, while lowering side‑channel exposure. The result: safer wallet signing and stronger Passkeys without user setup. With memory safety bugs driving roughly 70% of software flaws, this shift meaningfully hardens everyday security.
