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 units. This new safety expertise was made particularly to battle in opposition to surveillance distributors and the forms of vulnerabilities they depend on essentially the most, in accordance with Apple.
The function known as Reminiscence Integrity Enforcement (MIE) and is designed to assist cease reminiscence corruption bugs, that are a few of the most typical vulnerabilities exploited by spy ware builders and makers of telephone forensic units utilized by legislation enforcement.
“Identified mercenary spy ware chains used in opposition to iOS share a typical denominator with these concentrating on Home windows and Android: they exploit reminiscence security vulnerabilities, that are interchangeable, highly effective, and exist all through the business,” Apple wrote in its weblog put up.
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 units on the planet. The result’s prone to make life tougher for the businesses that make spy ware and zero-day exploits for planting spy ware on a goal’s telephone or extracting knowledge from them.
“The iPhone 17 might be now essentially the most safe computing surroundings on the planet that’s nonetheless related 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, instructed TechCrunch.
The researcher instructed TechCrunch that MIE will elevate the fee and time to develop their exploits for the newest iPhones, and consequently up their costs for paying prospects.
“It is a big deal,” mentioned the researcher, who requested to stay nameless to debate delicate issues. “It’s not hack proof. However it’s the closest factor we now have to hack proof. None of this can ever be 100% good. However it raises the stakes essentially the most.”

Jiska Classen, a professor and researcher who research iOS on the Hasso Plattner Institute in Germany, agreed that MIE will elevate the price of growing surveillance applied sciences.
Classen mentioned it is because a few of the bugs and exploits that spy ware corporations and researchers have that at present 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 spy ware distributors don’t have working exploits for the iPhone 17,” mentioned Classen.
“It will make their life arguably infinitely tougher,” mentioned Patrick Wardle, a researcher who runs a startup that makes cybersecurity merchandise particularly for Apple units. “In fact that’s mentioned with the caveat that it’s all the time a cat-and-mouse recreation.”
Wardle mentioned people who find themselves nervous about getting hacked with spy ware ought to improve to the brand new iPhones.
The specialists TechCrunch spoke to mentioned MIE will cut back the efficacy of each distant hacks, equivalent to these launched with spy ware like NSO Group’s Pegasus and Paragon’s Graphite. It would additionally assist to guard in opposition to bodily system hacks, equivalent to these carried out with telephone unlocking {hardware} like Cellebrite or Graykey.
Taking up the “majority of exploits”
Most fashionable units, together with nearly all of iPhones at the moment, run software program written in programming languages which are liable to memory-related bugs, usually referred to 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 person’s system the place it shouldn’t go.
Reminiscence-related bugs can enable malicious hackers to entry and management elements 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 knowledge saved within the telephone’s reminiscence, and exfiltrating it over the telephone’s web connection.
MIE goals to defend in opposition to these sorts of broad reminiscence assaults by vastly lowering the assault floor wherein reminiscence vulnerabilities might be exploited.
In line with Halvar Flake, an professional in offensive cybersecurity, reminiscence corruptions “are the overwhelming majority of exploits.”
MIE is constructed on a expertise referred to as Reminiscence Tagging Extension (MTE), initially developed by chipmaker Arm. In its weblog put up, Apple mentioned over the previous 5 years it labored with Arm to broaden and enhance the reminiscence security options right into a product referred to 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 rivals.
Google gives MTE for some Android units; the security-focused GrapheneOS, a customized model of Android, additionally gives MTE.
However different specialists say Apple’s MIE goes a step additional. Flake mentioned the Pixel 8 and GrapheneOS are “virtually comparable,” however the brand new iPhones might be “essentially the most safe mainstream” units.
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 spy ware and zero-days to set off a crash, making it simpler for Apple and safety researchers investigating assaults to identify them.
“A flawed step would result in a crash and a probably recoverable artifact for a defender,” mentioned Matthias Frielingsdorf, the vp of analysis at iVerify, an organization that makes an app to guard smartphones from spy ware. “Attackers already had an incentive to keep away from reminiscence corruption.”
Apple didn’t reply to a request for remark.
MIE might be on by default system huge, which implies it can shield apps like Safari and iMessage, which might be entry factors for spy ware. However third-party apps must implement MIE on their very own to enhance protections for his or her customers. Apple launched a model of EMTE for builders to do this.
In different phrases, MIE is a large step in the precise course, 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 approach.
“MIE is an effective factor and it’d even be a giant deal. It might considerably elevate 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 might be sellers,” mentioned Frielingsdorf.
