iPhone 17’s New MIE Feature Strengthens Crypto Wallet Security

Cobo founder DiscusFish has said that the new iPhone 17 introduces a new Memory Integrity Enforcement (MIE) feature that boosts crypto wallet ￰0￱ system is designed to block advanced memory attacks during crypto wallet signing by combining hardware and software ￰1￱ It Matters for Crypto Users Apple shared in a September 9 blog post that MIE is powered by the A19 chip and uses Enhanced Memory Tagging Extension (EMTE), which checks memory in ￰2￱ setup instantly blocks common exploits such as buffer overflows and use-after-free ￰3￱ the crypto industry, this is important because memory flaws account for nearly 70% of all software vulnerabilities and are a common entry point for malware during wallet ￰4￱ processes have always been a top target for hackers, as a single weak spot can lead to the theft of funds.

Apple’s new MIE steps in by stopping these attacks at the hardware level before they can cause ￰5￱ down these threats early makes wallet signing much safer and harder for spyware to steal ￰6￱ benefit is that protections are always on, meaning users do not need to set up anything ￰7￱ called the feature “a major win for high-net-worth crypto users and frequent signers.” Apple has also addressed side-channel risks with a function called Tag Confidentiality Enforcement (TCE), which prevents attackers from exposing memory tag values through speculative execution or other ￰8￱ closes another pathway often used by hackers to get wallet ￰9￱ company’s security team confirmed that MIE was tested against real-world exploit chains, with most attacks stopped in their earliest ￰10￱ reduces the opportunities for bad actors to compromise software.

Additionally, the protections go beyond Apple’s native ￰11￱ can also enable these features through Enhanced Security settings in Xcode, allowing crypto apps outside Apple’s ecosystem to benefit from the same defense ￰12￱ 17 Sets New Standard for Wallet Safety Overall, the new iPhone 17 reduces the risk of spyware targeting private keys by combining typed memory allocators, tag checks, and confidentiality ￰13￱ means that digital asset owners can reduce reliance on external hardware wallets or specialized devices for everyday signing. Elsewhere, a recent report from Web3 security firm CertiK revealed that more than $2.1 billion has already been lost to crypto-related attacks in ￰14￱ breaches account for the bulk of these losses, with compromised apps alone responsible for $1.6 ￰15￱ company added that this makes them the most damaging attack vector by a wide margin.
