Buried in an ocean of flashy novelties introduced by Apple this week, the tech big additionally revealed new safety know-how for its newest iPhone 17 and iPhone Air units. This new safety know-how was made particularly to combat towards surveillance distributors and the varieties of vulnerabilities they depend on probably the most, based on Apple.
The function 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 spy ware builders and makers of cellphone forensic units utilized by regulation enforcement.
“Identified mercenary spy ware chains used towards 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 blog post.
Cybersecurity consultants, together with individuals who make hacking instruments and exploits for iPhones, inform TechCrunch that this new safety know-how 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 cellphone or extracting knowledge 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, instructed TechCrunch.
The researcher instructed TechCrunch that MIE will increase the price and time to develop their exploits for the newest iPhones, and consequently up their costs for paying clients.
“This can be a large deal,” stated the researcher, who requested to stay nameless to debate delicate issues. “It’s not hack proof. However it’s the closest factor now we have to hack proof. None of this may ever be 100% good. However 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 stated it’s because a few of the bugs and exploits that spy ware firms and researchers have that at present work will cease working as soon as the brand new iPhones are out and MIE is applied.
“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,” stated Classen.
“It will make their life arguably infinitely tougher,” stated Patrick Wardle, a researcher who runs a startup that makes cybersecurity merchandise particularly for Apple units. “In fact that’s stated with the caveat that it’s all the time a cat and mouse sport.”
Wardle stated people who find themselves fearful about getting hacked with spy ware ought to improve to the brand new iPhones.
The consultants TechCrunch spoke to stated MIE will scale back the efficacy of each distant hacks, similar to these launched with spy ware like NSO Group’s Pegasus and Paragon’s Graphite. It can additionally assist to guard towards bodily gadget hacks, similar to these carried out with cellphone unlocking {hardware} like Cellebrite or Graykey.
Taking up the “majority of exploits”
Most trendy units, together with the vast majority of iPhones at present, 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 gadget 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 knowledge saved within the cellphone’s reminiscence, and exfiltrating it over the cellphone’s web connection.
MIE goals to defend towards these sorts of broad reminiscence assaults by vastly decreasing the assault floor wherein reminiscence vulnerabilities might 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 know-how referred to as Memory Tagging Extension (MTE) initially developed by chipmaker Arm. In its weblog put up, Apple stated over the previous 5 years it labored with Arm to increase 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 know-how, which takes benefit of Apple having full management of its know-how stack, from software program to {hardware}, in contrast to lots of its phone-making opponents.
Google offers MTE for some Android units; the security-focused GrapheneOS, a customized model of Android, additionally offers MTE.
However different consultants say Apple’s MIE goes a step additional. Flake stated the Pixel 8 and GrapheneOS are “nearly comparable,” however the brand new iPhones can be “probably 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 vital 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,” stated 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 can be on by default system huge, which implies it can shield apps like Safari and iMessage, which might be entry-points for spy ware. However third-party apps should implement MIE on their very own to enhance protections for his or her customers. Apple released a version of EMTE for builders to try this.
In different phrases, MIE is a large step in the precise route, however it can take a while to see its affect, 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 effective factor and it would even be an enormous deal. It might considerably increase the price for attackers and even power a few of them out of the market,” stated Frielingsdorf. “However there are going to be loads of unhealthy actors that may nonetheless discover success and maintain their enterprise.”
“So long as there are consumers there can be sellers,” stated Frielingsdorf.
