iPhone 17 offers built-in hardware crypto wallet protection

An advanced security feature built into iPhone 17 is reported to address iOS attacks, providing always-on memory safety protection across our devices. This feature, called Memory Integrity Enforcement (MIE), can provide crypto wallet holders with better security as it makes exploiting most memory corruption vulnerabilities inherently difficult. F2Pool and Cobo founder DiscussFish (@bitfish1) discussed MIE in an X post. 

“According to statistics, memory safety vulnerabilities account for 70% of all software vulnerabilities. This upgrade is simply a boon for high-net-worth users & frequent signers! Wallet signing and Passkeys are more secure – here comes the must-buy reason,” the post says.

Some users, meanwhile, argued that the feature makes attacks more difficult but there’s still a need for specialized security products. As Apple states, MIE targets high-end spyware, used by nation-states, which often exploit memory flaws to control devices. 

Apple states that MIE provides memory safety protection for critical parts of the device, including the kernel, the core part of the operating system that manages hardware and software interactions. The company clarifies that MIE operates synchronously, unlike standard memory tools that can leave gaps for attackers, ensuring continuous protection without affecting performance. Apple adds that developing MIE required extensive updates across Apple silicon, operating systems, and software frameworks, and builds on secure memory allocators with Enhanced Memory Tagging Extension (EMTE) and strict confidentiality policies. 

In recent years, Apple has addressed several zero-day vulnerabilities exploited in targeted attacks. In 2024, flaws in WebKit and the iOS kernel were patched after being actively exploited. In 2025, an out-of-bounds write vulnerability in the ImageIO framework was used in sophisticated attacks against specific individuals, prompting emergency updates across iOS, iPadOS, and macOS.
