Buried in an ocean of flashy novelties introduced by Apple this week, the tech large additionally revealed new security expertise for its newest iPhone 17 and iPhone Air units. This new security expertise was made particularly to battle towards surveillance distributors and the kinds of vulnerabilities they depend on essentially the most, in response to Apple.
The characteristic 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 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 publish.
Cybersecurity specialists, together with individuals who make hacking instruments and exploits for iPhones, inform information.killnetswitch that this new security expertise might make Apple’s latest iPhones a few of the most safe units on the planet. The result’s prone to make life more durable for the businesses that make spy ware and zero-day exploits for planting spy ware on a goal’s telephone or extracting information from them.
“The iPhone 17 might be now essentially the most safe computing atmosphere on the planet that’s nonetheless related to the web,” a security researcher, who has labored on creating and promoting zero-days and different cyber capabilities to the U.S. authorities for years, instructed information.killnetswitch.
The researcher instructed information.killnetswitch that MIE will increase the fee and time to develop their exploits for the newest iPhones, and consequently up their costs for paying prospects.
“This can be a large 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% excellent. 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 increase the price of creating surveillance applied sciences.
Classen mentioned it is 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,” 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 units. “After all that’s mentioned with the caveat that it’s at all times a cat-and-mouse sport.”
Wardle mentioned people who find themselves nervous about getting hacked with spy ware ought to improve to the brand new iPhones.
The specialists information.killnetswitch spoke to mentioned MIE will scale back the efficacy of each distant hacks, comparable to these launched with spy ware like NSO Group’s Pegasus and Paragon’s Graphite. It would additionally assist to guard towards bodily gadget hacks, comparable to these carried out with telephone unlocking {hardware} like Cellebrite or Graykey.
Taking up the “majority of exploits”
Most trendy units, together with the vast majority of iPhones immediately, run software program written in programming languages which are vulnerable 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 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 telephone’s reminiscence, and exfiltrating it over the telephone’s web connection.
MIE goals to defend towards these sorts of broad reminiscence assaults by vastly lowering the assault floor during which reminiscence vulnerabilities might be exploited.
In keeping with Halvar Flake, an skilled 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 publish, 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 security expertise, which takes benefit of Apple having full management of its expertise stack, from software program to {hardware}, not like lots of its phone-making opponents.
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 can 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 security 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 probably for spy ware and zero-days to set off a crash, making it simpler for Apple and security researchers investigating assaults to identify them.
“A mistaken 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 can be on by default system broad, which suggests it is going to defend apps like Safari and iMessage, which might be entry factors for spy ware. 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 do this.
In different phrases, MIE is a big step in the proper path, however it is going to take a while to see its influence, 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’d even be an enormous deal. It might considerably increase the fee for attackers and even drive 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 patrons there can be sellers,” mentioned Frielingsdorf.
