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 gadgets. This new safety know-how was made particularly to struggle towards surveillance distributors and the sorts of vulnerabilities they depend on probably the most, based on 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.
“Identified mercenary spyware and adware chains used towards iOS share a standard denominator with these focusing 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 submit.
Cybersecurity specialists, 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 gadgets on the planet. The result’s prone 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 atmosphere on the planet that’s nonetheless related to the web,” a safety researcher, who has labored on creating 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 associated fee and time to develop their exploits for the newest iPhones, and consequently up their costs for paying clients.
“This can be 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 now we have to hack proof. None of this can 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 creating surveillance applied sciences.
Classen mentioned it’s because a few of the bugs and exploits that spyware and adware corporations and researchers have that at the moment 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.
“It will make their life arguably infinitely harder,” mentioned Patrick Wardle, a researcher who runs a startup that makes cybersecurity merchandise particularly for Apple gadgets. “In fact that’s mentioned with the caveat that it’s at all times a cat-and-mouse recreation.”
Wardle mentioned people who find themselves nervous 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, reminiscent of these launched with spyware and adware like NSO Group’s Pegasus and Paragon’s Graphite. It should additionally assist to guard towards bodily gadget hacks, reminiscent of these carried out with cellphone unlocking {hardware} like Cellebrite or Graykey.
Taking up the “majority of exploits”
Most fashionable gadgets, together with nearly all of iPhones immediately, run software program written in programming languages which might be susceptible to memory-related bugs, typically referred to as reminiscence overflow or corruption bugs. When triggered, a reminiscence bug may 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 permit 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 information 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 lowering 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 Reminiscence Tagging Extension (MTE), initially developed by chipmaker Arm. In its weblog submit, Apple mentioned 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}, not like a lot of its phone-making rivals.
Google affords MTE for some Android gadgets; the security-focused GrapheneOS, a customized model of Android, additionally affords 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 will likely be “probably the most safe mainstream” gadgets.
MIE works by allocating every bit of a more recent 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 seemingly 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 flawed step would result in a crash and a probably 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 will likely be on by default system extensive, which suggests it would shield apps like Safari and iMessage, which might be entry factors for spyware and adware. However third-party apps should implement MIE on their very own to enhance protections for his or her customers. Apple launched a model of EMTE for builders to try this.
In different phrases, MIE is a large step in the appropriate path, however it would 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 effective factor and it would even be an enormous deal. It might considerably increase the associated fee for attackers and even drive a few of them out of the market,” mentioned 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 will likely be sellers,” mentioned Frielingsdorf.
