Apple on Tuesday unveiled its new iPhone 17 and iPhone Air smartphones, which embrace a brand new reminiscence safety function to safeguard units towards refined adware assaults.
The brand new function is named Reminiscence Integrity Enforcement (MIE) and the tech large says it offers always-on reminiscence security safety for the newest telephones. The brand new iPhone lineup is working iOS 26.
Apple identified that whereas its iOS working system has not been hit by widespread malware assaults, iPhones are commonly focused by well-resourced risk actors.
These assaults sometimes contain exploits created by ‘lawful’ surveillance options suppliers. These firms are also known as mercenary adware distributors as a result of whereas they declare to solely present their providers to authorities businesses for functions of nationwide safety and felony investigations, in actuality their merchandise are in lots of circumstances offered to authoritarian regimes and find yourself getting used towards journalists, human rights activists, and political dissidents.
The exploits developed by these adware distributors typically contain reminiscence security vulnerabilities and Apple’s new MIE safety goals to make exploitation of such flaws considerably tougher.
Based on Apple, the MIE function leverages Arm’s Enhanced Reminiscence Tagging Extension (EMTE), which the chip large launched in 2022 as an replace to its 2019 Reminiscence Tagging Extension (MTE) specification following a collaboration with Apple.
MIE makes use of EMTE together with safe reminiscence allocators, and in depth Tag Confidentiality Enforcement insurance policies to supply safety within the kernel, Safari, and Messages.
After testing MIE towards identified exploit chains and up to date vulnerabilities, Apple discovered that it’s extremely environment friendly in blocking assaults of their early phases, stopping risk actors from reviving exploit chains by swapping out one bug for one more.

“Inevitably, attackers should face MIE at a stage the place their capabilities are nonetheless very restricted, leaving few viable avenues for exploitation. This results in fragile chains the place breaking only one step is commonly sufficient to invalidate your entire exploit technique,” the tech large defined.
Ivan Krstić, head of safety engineering and structure at Apple, famous, “Based mostly on our evaluations pitting Reminiscence Integrity Enforcement towards exceptionally refined mercenary adware assaults from the final three years, we imagine MIE will make exploit chains considerably dearer and troublesome to develop and keep, disrupt most of the simplest exploitation methods from the final 25 years, and utterly redefine the panorama of reminiscence security for Apple merchandise.”
Google has additionally just lately introduced a brand new function, named Superior Safety mode, designed to dam adware and different assaults geared toward Android customers.
