Buried in an ocean of flashy novelties introduced by Apple this week, the tech large additionally revealed new safety expertise for its newest iPhone 17 and iPhone Air gadgets. This new safety expertise was made particularly to struggle in opposition to surveillance distributors and the sorts of vulnerabilities they depend on probably the most, in keeping with Apple.
The characteristic is known as Reminiscence Integrity Enforcement (MIE) and is designed to assist cease reminiscence corruption bugs, that are a few of the commonest vulnerabilities exploited by spyware and adware builders and makers of cellphone forensic gadgets utilized by legislation enforcement.
“Recognized mercenary spyware and adware chains used in opposition to iOS share a standard denominator with these concentrating on Home windows and Android: they exploit reminiscence security vulnerabilities, that are interchangeable, highly effective, and exist all through the trade,” Apple wrote in its blog post.
Cybersecurity specialists, together with individuals who make hacking instruments and exploits for iPhones, inform TechCrunch that this new safety expertise might make Apple’s latest iPhones a few of the most safe gadgets on the planet. The result’s more likely to make life tougher for the businesses that make spyware and adware and zero-day exploits for planting spyware and adware on a goal’s cellphone or extracting information from them.
“The iPhone 17 might be now probably the most safe computing surroundings on the planet that’s nonetheless linked to the web,” a safety researcher, who has labored on growing and promoting zero-days and different cyber capabilities to the U.S. authorities for years, advised TechCrunch.
The researcher advised TechCrunch that MIE will increase the fee and time to develop their exploits for the newest iPhones, and consequently up their costs for paying clients.
“This can be a large deal,” mentioned the researcher, who requested to stay nameless to debate delicate issues. “It’s not hack proof. Nevertheless it’s the closest factor we now have to hack proof. None of it will ever be 100% good. Nevertheless it raises the stakes probably the most.”

Jiska Classen, a professor and researcher who research iOS on the Hasso Plattner Institute in Germany, agreed that MIE will increase the price of growing surveillance applied sciences.
Classen mentioned it’s because a few of the bugs and exploits that spyware and adware firms and researchers have that presently work will cease working as soon as the brand new iPhones are out and MIE is carried out.
“I might additionally think about that for a sure time window some mercenary spyware and adware distributors don’t have working exploits for the iPhone 17,” mentioned Classen.
“This can make their life arguably infinitely harder,” mentioned Patrick Wardle, a researcher who runs a startup that makes cybersecurity merchandise particularly for Apple gadgets. “After all that’s mentioned with the caveat that it’s all the time a cat-and-mouse sport.”
Wardle mentioned people who find themselves fearful about getting hacked with spyware and adware ought to improve to the brand new iPhones.
The specialists TechCrunch spoke to mentioned MIE will scale back the efficacy of each distant hacks, resembling these launched with spyware and adware like NSO Group’s Pegasus and Paragon’s Graphite. It would additionally assist to guard in opposition to bodily system hacks, resembling these carried out with cellphone unlocking {hardware} like Cellebrite or Graykey.
Taking up the “majority of exploits”
Most fashionable gadgets, together with the vast majority of iPhones as we speak, run software program written in programming languages which might be liable to memory-related bugs, typically known as reminiscence overflow or corruption bugs. When triggered, a reminiscence bug could cause the contents of reminiscence from one app to spill into different areas of a consumer’s system the place it shouldn’t go.
Reminiscence-related bugs can enable malicious hackers to entry and management components of a tool’s reminiscence that they shouldn’t be permitted to. The entry can be utilized to plant malicious code that’s able to gaining broader entry to an individual’s information saved within the cellphone’s reminiscence, and exfiltrating it over the cellphone’s web connection.
MIE goals to defend in opposition to these sorts of broad reminiscence assaults by vastly decreasing the assault floor during which reminiscence vulnerabilities will be exploited.
In response to Halvar Flake, an knowledgeable in offensive cybersecurity, reminiscence corruptions “are the overwhelming majority of exploits.”
MIE is constructed on a expertise known as Memory Tagging Extension (MTE), initially developed by chipmaker Arm. In its weblog publish, Apple mentioned over the previous 5 years it labored with Arm to develop and enhance the reminiscence security options right into a product known as Enhanced Reminiscence Tagging Extension (EMTE).
MIE is Apple’s implementation of this new safety expertise, which takes benefit of Apple having full management of its expertise stack, from software program to {hardware}, in contrast to a lot of its phone-making opponents.
Google offers MTE for some Android gadgets; the security-focused GrapheneOS, a customized model of Android, additionally offers MTE.
However different specialists say Apple’s MIE goes a step additional. Flake mentioned the Pixel 8 and GrapheneOS are “nearly comparable,” however the brand new iPhones can be “probably the most safe mainstream” gadgets.
MIE works by allocating every bit of a more moderen iPhone’s reminiscence with a secret tag, successfully its personal distinctive password. This implies solely apps with that secret tag can entry the bodily reminiscence sooner or later. If the key doesn’t match, the safety protections kick in and block the request, the app will crash, and the occasion is logged.
That crash and log is especially important because it’s extra doubtless for spyware and adware and zero-days to set off a crash, making it simpler for Apple and safety researchers investigating assaults to identify them.
“A mistaken step would result in a crash and a doubtlessly recoverable artifact for a defender,” mentioned Matthias Frielingsdorf, the vice chairman of analysis at iVerify, an organization that makes an app to guard smartphones from spyware and adware. “Attackers already had an incentive to keep away from reminiscence corruption.”
Apple didn’t reply to a request for remark.
MIE can be on by default system vast, which implies it can defend apps like Safari and iMessage, which will be entry factors for spyware and adware. However third-party apps must implement MIE on their very own to enhance protections for his or her customers. Apple released a version of EMTE for builders to do this.
In different phrases, MIE is a big step in the fitting path, however it can take a while to see its impression, relying on what number of builders implement it and the way many individuals purchase new iPhones.
Some attackers will inevitably nonetheless discover a manner.
“MIE is an efficient factor and it’d even be a giant deal. It might considerably increase the fee for attackers and even power a few of them out of the market,” mentioned Frielingsdorf. “However there are going to be loads of dangerous actors that may nonetheless discover success and maintain their enterprise.”
“So long as there are consumers there can be sellers,” mentioned Frielingsdorf.
