Apple has released a software update that deals with an issue that could allow deleted notifications to be retrieved. Something that, in at least one reported case, was used by law enforcement during forensic analysis.
Apple fixed the issue in iOS and iPadOS versions 18.7.8 and 26.4.2 (check availability for your device at those links). The update deals with a singular security vulnerability, tracked as CVE-2026-28950.
Although the description is brief—“a logging issue was addressed with improved data redaction”—the impact points us in the right direction.
“Notifications marked for deletion could be unexpectedly retained on the device.”
This suggests that Apple’s bug was that iOS kept copies of notification content in an internal database for longer than intended, even after the messages “disappeared” or the app was uninstalled. In a case reported by 404 Media, law enforcement was able to recover those notifications using standard forensic tools once they had access to the unlocked device. The example in that reported case involved Signal.
“The FBI was able to forensically extract copies of incoming Signal messages from a defendant’s iPhone, even after the app was deleted, because copies of the content were saved in the device’s push notification database.”
Before we go into the update process, you may want to know that you can mute or hide notifications in Signal, which also protects them from prying eyes. In Signal, open your Settings and tap on Notifications. You can adjust several settings there. For example, I have mine set so I only see the name of the sender.
Install the update
For iOS and iPadOS users, you can check if you’re using the latest software version by going to Settings > General > Software Update. It’s also worth turning on Automatic Updates if you haven’t already. You can do that on the same screen.

Scammers have found a way to abuse legitimate Apple account notification emails to trick targets into calling fake tech support numbers.
According to a report from BleepingComputer, scammers create an Apple account and insert a phishing message into the personal information fields, then modify the account so that Apple sends a genuine security alert about the change to the target.
BleepingComputer was able to replicate the attack.
The attacker creates an Apple ID they control, then stuffs the phishing message into the personal information fields (first name, last name, possibly address), splitting it across fields because they will not fit into just one.
To launch the phish, the attacker changes something benign on their specially created Apple account, such as shipping information, which causes Apple’s systems to send a “Your Apple account was updated” security email.
While the original alert is addressed to the attacker’s iCloud email, they are then able to redistribute it to a wider victim list, for example through a mailing list.
In the copy the targets receive, the email headers still show a legitimate Apple sender, and the presence of the attacker’s iCloud address can even make it look like “someone else” has gained access to the account.
Because Apple includes those user-supplied fields in the security email, the phishing text is delivered inside a legitimate message sent from Apple’s own infrastructure.
This method, called call-back phishing, filters out suspicious users, so the scammers can focus on the people who fell for the first part.
The emails come from a legitimate source, sail through every security filter because of that, and look convincing enough to scare the receiver into thinking someone spent $899 from their PayPal account.
But the structure of the email does not make sense.
“Dear User” is immediately followed by the scam message where your name should have been. The header says it’s about account information rather than a purchase. And the iCloud account does not belong to the recipient. So, once you know how it’s done, they’re not impossible to spot. Which is why we wrote this blog.
And when in doubt, you can always ask Malwarebytes Scam Guard.
Scam Guard identified the screenshot as a scam and guides users through the next steps.
Scams like these work, because many users still view phone calls as more trustworthy than email, especially if the email itself passed all the usual technical authenticity checks and they initiated the call themselves.
How to stay safe
Tech support scammers will try to convince callers to install some kind of remote desktop application to steal data from your computer, or ask for financial details so they can steal your money.
To stay safe from these scammers:
Be wary of unexpected alerts about high‑value purchases you do not recognize. They are suspicious even if they come from a real domain.
Never call a number sent to you by unsolicited means or even found in sponsored search results.
Carefully read emails and text messages, even if they come form trustworthy addresses. Does the email make sense from a structural and linguistic point of view?
If someone claiming to be support for a legitimate company asks for remote access or payment details during a call, hang up and contact the company through official channels.

DarkSword and Coruna are two new tools for invisible attacks on iOS devices. These attacks require no user interaction and are already being actively used by bad actors in the wild. Before these threats emerged, most iPhone users didn’t have to lose sleep over their data security. Protection was really only a major concern for a narrow group — politicians, activists, diplomats, high-level business execs, and others who handle extremely sensitive data — who might be targeted by foreign intelligence agencies. We’ve covered sophisticated spyware used against such a group before — noting how hard to come by those tools were.
However, DarkSword and Coruna — discovered by researchers earlier this year — are total game-changers. This malware is being used for mass infections of everyday users. In this post, we dive into why this shift happened, why these tools are so dangerous, and how you can stay protected.
What we know about DarkSword, and how it can target your iPhone
In mid-March 2026, three separate research teams coordinated the release of their findings on a new spyware strain called DarkSword. This tool is capable of silently hacking devices running iOS 18 without the user ever knowing something is wrong.
First, we should clear up some confusion: iOS 18 isn’t as vintage as it might sound. Even though the latest version is iOS 26, Apple recently overhauled its versioning system, which threw everyone for a loop. They decided to jump ahead eight versions — from 18 straight to 26 — so the OS number matches the current year. Despite the jump, Apple estimates that about a quarter of all active devices still run iOS 18 or older.
With that cleared up, let’s get back to DarkSword. Research shows that this malware infects victims when they visit perfectly legitimate websites that have been injected with malicious code. The spyware installs itself without any user interaction at all: you just have to land on a compromised page. This is what’s known as a zero-click infection technique. Researchers report that several thousand devices have already been hit this way.
To compromise a device, DarkSword uses a six-vulnerability exploit chain to escape the sandbox, escalate privileges, and execute code. Once it’s in, the malware harvests data from the infected device, including:
Passwords
Photos
Chats and data from iMessage, WhatsApp, and Telegram
Browser history
Information from Apple’s Calendar, Notes, and Health apps
On top of all that, DarkSword lets attackers scoop up crypto-wallet data, making it essentially dual-purpose malware that functions as both a spy tool and a way to drain your crypto.
The only bit of good news is that the spyware doesn’t survive a reboot. DarkSword is fileless malware, meaning it lives in the device’s RAM, and never actually embeds itself into the file system.
Coruna: how older iOS versions are being targeted
Just two weeks before the DarkSword findings went public, researchers flagged another iOS threat dubbed Coruna. This malware is capable of compromising devices running older software — specifically iOS 13 through 17.2.1. Coruna uses the exact same playbook as DarkSword: victims visit a legitimate site injected with malicious code which then drops the malware onto the device. The whole process is completely invisible and requires zero user interaction.
A deep dive into Coruna’s code revealed it exploits a total of 23 different iOS vulnerabilities, several of which are tucked away in Apple’s WebKit. It’s worth reminding that, generally speaking (outside the EU), all iOS browsers are required to use the WebKit engine. This means these vulnerabilities don’t just affect Safari users — they’re a threat to anyone using a third-party browser on their iPhone as well.
The latest version of Coruna, much like DarkSword, includes modifications designed to drain crypto wallets. It also harvests photos and, in certain instances, email data. From what we can tell, stealing cryptocurrency seems to be the primary motive behind Coruna’s widespread deployment.
Who created Coruna and DarkSword — and how did they end up in the wild?
Code analysis of both tools suggests that Coruna and DarkSword were likely built by different developers. However, in both cases, we’re looking at software originally created by state-affiliated companies, possibly from the U.S. The high quality of the code points to this; these aren’t just Frankenstein kits cobbled together from random parts, but uniformly engineered exploits. Somewhere along the line, these tools leaked into the hands of cybercrime gangs.
One theory suggests an employee at the company that developed Coruna sold it to hackers. Since then, the malware has been used to drain crypto wallets belonging to users in China; experts estimate that at least 42 000 devices were infected there alone.
As for DarkSword, cybercriminals have already used it to compromise users in Saudi Arabia, Turkey, and Malaysia. The problem is exacerbated by the fact that the attackers who first deployed DarkSword left the full source code on infected websites, meaning it could easily be picked up by other criminal groups.
The code also includes detailed comments in English explaining exactly what each component does, which supports the theory of its Western origins. These step-by-step instructions make it easy for other hackers to adapt the tool for their own purposes.
How to protect yourself from Coruna and DarkSword
Serious malware that allows for the mass infection of iPhones while requiring zero interaction from the user has now landed in the hands of an essentially unlimited pool of cybercriminals. To pick up Coruna or DarkSword, you simply have to visit the wrong site at the wrong time. So this is one of those cases where every user needs to take iOS security seriously — not just those in high-risk groups.
The best thing you can do to protect yourself from Coruna and DarkSword is to update your devices to the latest version of iOS or iPadOS 26, as soon as you can. If you can’t update to the newest software — for instance, if your device is older and doesn’t support iOS 26 — you should still install the latest version available to you. Specifically, look for versions 15.8.7, 16.7.15, or 18.7.7. In a rare move, Apple patched a wide range of older operating systems.
To protect your Apple devices from similar malware that will likely pop up in the future, we recommend the following:
Install updates promptly on all your Apple devices. The company regularly releases OS versions that patch known vulnerabilities — don’t skip them.
Enable Background Security Improvements. This feature allows your device to receive critical security fixes separately from full iOS updates, reducing the window for hackers to exploit vulnerabilities. To enable it, go to Settings → Privacy & Security → Background Security Improvements and turn on the Automatically Install
Consider using Lockdown Mode. This is a heightened security setting that limits some device features but simultaneously blocks or significantly complicates attacks. To enable this, go to Settings → Privacy & Security → Lockdown Mode → Turn On Lockdown Mode.
Reboot your device once a day (or more). This stops fileless malware in its tracks, since these threats aren’t embedded in the system and disappear after a restart.
Use encrypted storage for sensitive data. Keep things like crypto wallet keys, photos of IDs, and confidential info in a secure vault. Kaspersky Password Manager is a great fit for this; it manages your passwords, two-factor authentication tokens, and passkeys across all your devices while also keeping your notes, photos, and docs synced and encrypted.
The idea that Apple devices are bulletproof is a myth. They’re vulnerable to zero-click attacks, Trojans, and ClickFix infection techniques — and we’ve even seen malicious apps slip into the App Store more than once. Read more here:
Apple heeft sinds 2022 een speciale lockdownmodus ingebouwd in zijn iPhones. Die is bedoeld voor wie mogelijk doelwit is van een geavanceerde cyberaanval. Volgens Apple werkt de modus zo goed, dat het nog geen hacker is gelukt om door de beveiliging heen te breken van iemand die de modus aan heeft staan.
On March 4, 2026, Google and iVerify published reports about a highly sophisticated exploit kit targeting Apple iPhone devices. According to Google, the exploit kit was first discovered in targeted attacks conducted by a customer of an unnamed surveillance vendor. It was later used by other attackers in watering-hole attacks in Ukraine and in financially motivated attacks in China. Additionally, researchers discovered an instance with the debug version of the exploit kit, which revealed the internal names of the exploits and the framework name used by its developers — Coruna. Analysis of the kit showed that it relies on the exploitation of many previously patched vulnerabilities and also includes exploits for CVE-2023-32434 and CVE-2023-38606. These two vulnerabilities particularly caught our attention because they had been first discovered as zero-days used in Operation Triangulation.
Operation Triangulation is a complex mobile APT campaign targeting iOS devices. We discovered it while monitoring the network traffic of our own corporate Wi-Fi network. We noticed suspicious activity that originated from several iOS-based phones. Following the investigation, we learned that this campaign employed a sophisticated spyware implant and multiple zero-day exploits. The investigation lasted for over six months, during which we disclosed our findings in connection to the attack. Kaspersky GReAT experts also presented these findings at the 37th Chaos Communication Congress (37C3).
Although all the details of both CVE-2023-32434 and CVE-2023-38606 have long been publicly available, and other researchers have developed their own exploits without ever seeing the Triangulation code, we decided to closely investigate the exploits used in Coruna. Some of the exploit kit distribution links provided by Google remained active at the time the report was published, which allowed us to collect, decrypt, and analyze all components of Coruna.
During our analysis, we discovered that the kernel exploit for CVE-2023-32434 and CVE-2023-38606 vulnerabilities used in Coruna, in fact, is an updated version of the same exploit that had been used in Operation Triangulation. The images below illustrate a high-level overview of the two attack chains. The exploit in question is highlighted with a red rectangle.
Attack chain of Operation Triangulation (simplified)
Attack chain of Coruna (simplified)
Moreover, we discovered that Coruna includes four additional kernel exploits that we had not seen used in Operation Triangulation, two of which were developed after the discovery of Operation Triangulation. All of these exploits are built on the same kernel exploitation framework and share common code. Code similarities from kernel exploits can also be found in other components of Coruna. These findings led us to conclude that this exploit kit was not patchworked but rather designed with a unified approach. We assume that it’s an updated version of the same exploitation framework that was used — at least to some extent — in Operation Triangulation.
Technical details
While we continue to investigate all exploits and vulnerabilities used by Coruna, this post provides a high-level overview of the exploit kit and attack chain.
Safari
Exploitation begins with a stager that fingerprints the browser and selects and executes appropriate remote code execution (RCE) and pointer authentication code (PAC) exploits depending on the browser version. It also contains a URL to an encrypted file with information about all available packages containing exploits and other components. The stager also includes a 256-bit key used to decrypt it. The URL and decryption key are passed to a payload embedded in PAC exploits.
Payload
The payload is responsible for initiating the exploitation of the kernel. After initialization, the payload first downloads a file with information about other available components. To extract it, the payload performs several steps processing multiple file formats.
First, the downloaded file is decrypted using the ChaCha20 stream cipher. Decryption yields a container with the magic number 0xBEDF00D, which stores LZMA-compressed data.

We provide a description of all possible File ID values below. At this stage, when the payload gathers information about all available file packages, this container holds only one file, and its File ID is 0x70000.
Finally, we get to the file with information about all available file packages. It starts with the magic value 0x12345678. The exploit kit uses this file format to obtain URLs and decryption keys for additional components that need to be downloaded.

The components required for exploiting a targeted device are selected using the Package ID. Its high byte specifies the package type and required hardware. We’ve seen the following package types:
0xF2 – exploit for ARM64,
0xF3 – exploit for ARM64E,
0xA2 – Mach-O loader for ARM64,
0xA3 – Mach-O loader for ARM64E,
2 – implant for ARM64,
0xE2 – implant for ARM64E.
The payload code also supports additional package types, such as 0xF1, an exploit for older ARM devices that do not support 64-bit architecture. Interestingly, however, the files for such exploits are missing.
Other bytes of the Package ID define the supported firmware version and CPU generation.

The files inside these packages are also stored in encrypted and compressed 0xF00DBEEF containers, but this time compression is optional and is determined by the second bit in the Flags field. Different packages contain different sets of files. A description of all possible File IDs is given in the table below.

After downloading the necessary components, the payload begins executing kernel exploits, Mach-O loaders, and the malware launcher. The payload selects an appropriate Mach-O loader based on the firmware version, CPU, and presence of the iokit-open-service permission.
Kernel exploits
We analyzed all five kernel exploits from the kit and discovered that one of them is an updated version of the same exploit we discovered in Operation Triangulation. There are many small changes, but the most noticeable are as follows:
The code takes into account more values from XNU version strings, allowing for more accurate version checking.
Added a check for iOS 17.2. We assume that this was the latest version of iOS at the time of development (released in December 2023).
Added checks for newer Apple processors: A17, M3, M3 Pro, M3 Max (released in fall 2023).
Added a check for iOS version 16.5 beta 4. This version patched the exploit after our report to Apple.
Why does the exploit need to check for iOS 17.2 and newer CPUs if the targeted vulnerabilities were fixed in iOS 16.5 beta 4? The answer can be found by examining other exploits: they are all based on the same source code. The only difference is in the vulnerabilities they exploit, so these checks were added to support the newer exploits and appeared in the older version after recompilation.
Launcher
The launcher is responsible for orchestrating the post-exploitation activities. It also uses the kernel exploit and the interface it provides. However, since the exploit creates special kernel objects during its execution that provide the ability to read and write to kernel memory, the launcher simply reuses these objects without the need to trigger vulnerabilities and go through the entire exploitation path again. The launcher cleans up exploitation artifacts, retrieves the process name for injection from a config with the 0xDEADD00F magic number, injects a stager into the target process, uses it to execute itself, and launches the implant.
Conclusions
This case demonstrates once again the dangers associated with such malicious tools that lie in their potential wide usage. Originally developed for cyber-espionage purposes, this framework is now being used by cybercriminals of a broader kind, placing millions of users with unpatched devices at risk. Given its modular design and ease of reuse, we expect that other threat actors will begin incorporating it into their attacks. We strongly recommend that users install the latest security updates as soon as possible, if they have not already done so.

The components required for exploiting a targeted device are selected using the Package ID. Its high byte specifies the package type and required hardware. We’ve seen the following package types:
0xF2 – exploit for ARM64,
0xF3 – exploit for ARM64E,
0xA2 – Mach-O loader for ARM64,
0xA3 – Mach-O loader for ARM64E,
2 – implant for ARM64,
0xE2 – implant for ARM64E.
The payload code also supports additional package types, such as 0xF1, an exploit for older ARM devices that do not support 64-bit architecture. Interestingly, however, the files for such exploits are missing.
Other bytes of the Package ID define the supported firmware version and CPU generation.

After downloading the necessary components, the payload begins executing kernel exploits, Mach-O loaders, and the malware launcher. The payload selects an appropriate Mach-O loader based on the firmware version, CPU, and presence of the iokit-open-service permission.
Kernel exploits
We analyzed all five kernel exploits from the kit and discovered that one of them is an updated version of the same exploit we discovered in Operation Triangulation. There are many small changes, but the most noticeable are as follows:
The code takes into account more values from XNU version strings, allowing for more accurate version checking.
Added a check for iOS 17.2. We assume that this was the latest version of iOS at the time of development (released in December 2023).
Added checks for newer Apple processors: A17, M3, M3 Pro, M3 Max (released in fall 2023).
Added a check for iOS version 16.5 beta 4. This version patched the exploit after our report to Apple.
Why does the exploit need to check for iOS 17.2 and newer CPUs if the targeted vulnerabilities were fixed in iOS 16.5 beta 4? The answer can be found by examining other exploits: they are all based on the same source code. The only difference is in the vulnerabilities they exploit, so these checks were added to support the newer exploits and appeared in the older version after recompilation.
Launcher
The launcher is responsible for orchestrating the post-exploitation activities. It also uses the kernel exploit and the interface it provides. However, since the exploit creates special kernel objects during its execution that provide the ability to read and write to kernel memory, the launcher simply reuses these objects without the need to trigger vulnerabilities and go through the entire exploitation path again. The launcher cleans up exploitation artifacts, retrieves the process name for injection from a config with the 0xDEADD00F magic number, injects a stager into the target process, uses it to execute itself, and launches the implant.
Conclusions
This case demonstrates once again the dangers associated with such malicious tools that lie in their potential wide usage. Originally developed for cyber-espionage purposes, this framework is now being used by cybercriminals of a broader kind, placing millions of users with unpatched devices at risk. Given its modular design and ease of reuse, we expect that other threat actors will begin incorporating it into their attacks. We strongly recommend that users install the latest security updates as soon as possible, if they have not already done so.
Apple has released a Background Security Improvement to patch a flaw that could allow malicious websites to bypass browser protections and access data from other sites.
What is it?
The patched WebKit vulnerability is described as:
“A cross-origin issue in the Navigation API was addressed with improved input validation.”
WebKit vulnerabilities refer to security flaws in Apple’s web rendering engine, which powers Safari, Mail, and the App Store on iOS and macOS.
What this means is that the CVE-2026-20643 vulnerability makes it possible for a malicious website to pretend to be another site, maybe one you trust, and then read or steal information that should be kept separate. Normally, browsers enforce a rule called the “same‑origin policy,” which is like a strict fence that stops one site from peeking into another site’s data. This bug could help cybercriminals cut through that fence.
In practical terms, an attacker would first have to lure you to a specially crafted web page. If you visited it, that page could try to bypass the normal isolation between sites and access things it should not see, such as data from another tab or embedded content from a different service.
Attackers do not currently appear to exploit this flaw in the wild, but they like to chain issues like this with other bugs to steal accounts or sensitive data, which likely prompted Apple to ship it as a Background Security Improvement. Apple’s fix tightens how WebKit checks and handles cross‑site navigation.
What to do
This patch for a WebKit vulnerability, tracked as CVE-2026-20643, installs on top of versions 26.3.1/26.3.2 and not as a separate full OS version. Background Security Improvements are only available on the latest OS branch (26.x) and apply silently in the background if you’re on the latest version.
For iOS and iPadOS users, you can check if you’re using the latest software version by going to Settings > General > Software Update. It’s also worth turning on Automatic Updates if you haven’t already. You can do that on the same screen.
For macOS Tahoe users, you can find out if you’re on the latest 26.3 version from the Apple menu. In the upper-left corner of your screen, choose About This Mac. The information shown there includes the macOS name and version number. If you need to know the build number as well, click the version number to see it.
This Background Security Improvement is only available for Mac users running Tahoe 26.3.1 and MacBook Neo users running 26.3.2.
All users have to do is to check if they have the Background Security Improvements option set to enabled.
For iPhone and iPad users, this setting can be found under Privacy & Security, where you can scroll down and look for the Background Security Improvements toggle.
Automatically install security improvements
On a Mac (macOS Tahoe 26.3.+ only), you can check by following these instructions:
Click the Apple menu > System Settings.
In the sidebar, click Privacy& Security.
Scroll down on the right and click Background Security Improvements.
Make sure Automatically Install is turned on. If it’s off, the Mac won’t get Background Security Improvements until the fixes are rolled into a later full update.
The Install option in my screenshot means that you can speed up the process by clicking it. But it’s fine to wait until it happens automatically.
After the update, your OS version should show 26.3.1 (a), except for MacBook Neos which should be at 26.3.2 (a).
We don’t just report on phone security—we provide it
Cybersecurity researchers have taken a close look at the inner workings of the Predator spyware, developed by the Cyprus-based company Intellexa. Rather than focusing on how the spyware initially infects a device, this latest research zooms in on how the malware behaves once a device has already been compromised.
The most fascinating discovery involves the mechanisms the Trojan uses to hide iOS camera and microphone indicators. By doing so, it can covertly spy on the infected user. In today’s post, we break down what Predator spyware actually is, how the iOS indicator system is designed to work, and how this malware manages to disable these indicators.
What Predator is, how it works, and what… Alien has to do with it
We previously took a deep dive into the most notorious commercial spyware out there in a dedicated feature — where we discussed the star of today’s post, Predator, among the others. You can check out that earlier post for a detailed review of this spyware, but for now, here’s a quick refresher on the essentials.
Predator was originally developed by a North Macedonian company named Cytrox. It was later acquired by the aforementioned Intellexa, a Cyprus-registered firm owned by a former Israeli intelligence officer — a truly international spy games collaboration.
Strictly speaking, Predator is the second half of a spyware duo designed to monitor iOS and Android users. The first component is named Alien; it’s responsible for compromising a device and installing Predator. As you might’ve guessed, these pieces of malware are named after the famous Alien vs. Predator franchise.
An attack using Intellexa’s software typically begins with a message containing a malicious link. When the victim clicks it, they’re directed to a site that leverages a chain of browser and OS vulnerabilities to infect the device. To keep things looking normal and avoid raising suspicion, the user is then redirected to a legitimate website.
Besides Alien, Intellexa offers several other delivery vehicles for landing Predator on a target’s device. These include the Mars and Jupiter systems, which are installed on the service provider’s side to infect devices through a man-in-the-middle attack.
Predator spyware for iOS comes packed with a wide array of surveillance tools. Most notably, it can record and transmit data from the device’s camera and microphone. Naturally, to keep the user from catching on to this suspicious activity, the system’s built-in recording indicators — the green and orange dots at the top of the screen — must be disabled. While it’s been known for some time that Predator could somehow hide these alerts, it’s only thanks to this research that we know how exactly it pulls it off.
How the iOS camera and microphone indicator system works
To understand how Predator disables these indicators, we first need to look at how iOS handles them. Since the release of iOS 14 in 2020, Apple devices have alerted users whenever the microphone or camera is active by displaying an orange or green dot at the top of the screen. If both are running simultaneously, only the green dot is shown.
In iOS 14 and later, an orange dot appears at the top of the screen when the microphone is in use. Source
Just like other iOS user interface elements, recording indicators are managed by a process called SpringBoard, which is responsible for the device’s system-wide UI. When an app starts using the camera or microphone, the system registers the change in that specific module’s state. This activity data is then gathered by an internal system component, which passes the information to SpringBoard for processing. Once SpringBoard receives word that the camera or microphone is active, it toggles the green or orange dot on or off based on that data.
If the camera is in use (or both the camera and microphone are), a green dot appears. Source
From an app’s perspective, the process works like this: first, the app requests permission to access the camera or microphone through the standard iOS permission mechanism. When the app actually needs to use one or both of these modules, it calls the iOS system API. If the user has granted permission, iOS activates the requested module and automatically updates the status indicator. These indicators are strictly controlled by the operating system; third-party apps have no direct access to them.
How Predator interferes with the iOS camera and microphone indicators
Cybersecurity researchers analyzed a captured version of Predator and uncovered traces of multiple techniques used by the spyware’s creators to bypass built-in iOS mechanisms and disable recording indicators.
In the first approach — which appears to have been used during early development — the malware attempted to interfere with the indicators at the display stage right after SpringBoard received word that the camera or microphone was active. However, this method was likely deemed too complex and unreliable by the developers. As a result, this specific function remains in the Trojan as dead code — it’s never actually executed.
Ultimately, Predator settled on a simpler, more effective method that operates at the very level where the system receives data about the camera or microphone being turned on. To do this, Predator intercepts the communication between SpringBoard and the specific component responsible for collecting activity data from these modules.
By exploiting the specific characteristics of Objective-C — the programming language used to write the SpringBoard application — the malware completely blocks the signals indicating that the camera or microphone has been activated. As a result, SpringBoard never receives the signal that the module’s status has changed, so it never triggers the recording indicators.
How to lower your risk of spyware infection
Predator-grade spyware is quite expensive, and typically reserved for high-stakes industrial or state-sponsored espionage. On one hand, this means defending against such a high-tier threat is difficult — and achieving 100% protection is likely impossible. On the other hand, for these same reasons, the average user is statistically unlikely to be targeted.
However, if you’ve reason to believe you’re at risk from Predator or Pegasus-class spyware, here are a few steps you can take to make an attacker’s job much harder:
Don’t click suspicious links from unknown senders.
Regularly update your operating system, browsers, and messaging apps.
Reboot your device occasionally. A simple restart can often help “lose the tail”, forcing attackers to reinfect the device from scratch.
…iPhone and iPad are the first and only consumer devices in compliance with the information assurance requirements of NATO nations. This enables iPhone and iPad to be used with classified information up to the NATO restricted level without requiring special software or settings—a level of government certification no other consumer mobile device has met.
This is out of the box, no modifications required.
On March 3, 2026, Google warned about a powerful exploit kit targeting Apple iPhone models running iOS version 13.0 (released in September 2019) up to version 17.2.1 (released in December 2023).
In the latest security updates, Apple patched the vulnerabilities used in the Coruna exploit kit for older mobile devices that can no longer be updated to the latest iOS version. For newer iOS versions, patches associated with the Coruna exploit were already shipped in iOS 16.6 through 17.2 in updates released in 2023 and 2024.
The Coruna exploit kit was first observed in highly targeted attacks, but was later seen in watering hole attacks targeting Ukrainian users by a suspected Russian espionage group. Later still, it appeared on a very large set of fake Chinese financial websites, suggesting the exploit was being used by more mainstream cybercriminals.
The exploit relies on WebKit vulnerabilities (CVE-2023-43000 and CVE-2024-23222) that can be triggered by processing maliciously crafted web content, and then gains kernel privileges by abusing a separate kernel vulnerability tracked as CVE-2023-41974.
The table below shows which updates are available and points you to the relevant security content for that operating system (OS).
Apple heeft nieuwe beveiligingsupdates uitgerold voor oudere iPhones om een gevaarlijk lek te dichten dat bekendstaat als Coruna. Het gaat om de updates iOS 15.8.7 en iOS 16.7.15 waarmee toestellen tot de iPhone 6s worden beschermd.
If you don’t go searching for AI services, they’ll find you all the same. Every major tech company feels a moral obligation not just to develop an AI assistant, integrated chatbot, or autonomous agent, but to bake it into their existing mainstream products and forcibly activate it for tens of millions of users. Here are just a few examples from the last six months:
Google activated Gemini for all U.S. Chrome users, cranked its browser functionality to the max, aggressively expanded the reach of AI Overviews in search results, and baked a whole suite of AI features into its online services (Gmail, Google Docs, and others).
Apple integrated its own Apple Intelligence (conveniently sharing the AI acronym) into the latest OS versions across all device types and most of its native apps.
On the flip side, geeks have rushed to build their own “personal Jarvises” by renting VPS instances or hoarding Mac minis to run the OpenClaw AI agent. Unfortunately, OpenClaw’s security issues with default settings turned out to be so massive that it’s already been dubbed the biggest cybersecurity threat of 2026.
Beyond the sheer annoyance of having something shoved down your throat, this AI epidemic brings some very real practical risks and headaches. AI assistants hoover up every bit of data they can get their hands on, parsing the context of the websites you visit, analyzing your saved documents, reading through your chats, and so on. This gives AI companies an unprecedentedly intimate look into every user’s life.
A leak of this data during a cyberattack — whether from the AI provider’s servers or from the cache on your own machine — could be catastrophic. These assistants can see and cache everything you can, including data usually tucked behind multiple layers of security: banking info, medical diagnoses, private messages, and other sensitive intel. We took a deep dive into how this plays out when we broke down the issues with the AI-powered Copilot+ Recall system, which Microsoft also planned to force-feed to everyone. On top of that, AI can be a total resource hog, eating up RAM, GPU cycles, and storage, which often leads to a noticeable hit to system performance.
For those who want to sit out the AI storm and avoid these half-baked, rushed-to-market neural network assistants, we’ve put together a quick guide on how to kill the AI in popular apps and services.
How to disable AI in Google Docs, Gmail, and Google Workspace
Google’s AI assistant features in Mail and Docs are lumped together under the umbrella of “smart features”. In addition to the large language model, this includes various minor conveniences, like automatically adding meetings to your calendar when you receive an invite in Gmail. Unfortunately, it’s an all-or-nothing deal: you have to disable all of the “smart features” to get rid of the AI.
To do this, open Gmail, click the Settings (gear) icon, and then select See all settings. On the General tab, scroll down to Google Workspace smart features. Click Manage Workspace smart feature settings and toggle off two options: Smart features in Google Workspace and Smart features in other Google products. We also recommend unchecking the box next to Turn on smart features in Gmail, Chat, and Meet on the same general settings tab. You’ll need to restart your Google apps afterward (which usually happens automatically).
How to disable AI Overviews in Google Search
You can kill off AI Overviews in search results on both desktops and smartphones (including iPhones), and the fix is the same across the board. The simplest way to bypass the AI overview on a case-by-case basis is to append -ai to your search query — for example, how to make pizza -ai. Unfortunately, this method occasionally glitches, causing Google to abruptly claim it found absolutely nothing for your request.
If that happens, you can achieve the same result by switching the search results page to Web mode. To do this, select the Web filter immediately below the search bar — you’ll often find it tucked away under the More button.
A more radical solution is to jump ship to a different search engine entirely. For instance, DuckDuckGo not only tracks users less and shows little ads, but it also offers a dedicated AI-free search — just bookmark the search page at noai.duckduckgo.com.
How to disable AI features in Chrome
Chrome currently has two types of AI features baked in. The first communicates with Google’s servers and handles things like the smart assistant, an autonomous browsing AI agent, and smart search. The second handles locally more utility-based tasks, such as identifying phishing pages or grouping browser tabs. The first group of settings is labeled AI mode, while the second contains the term Gemini Nano.
To disable them, type chrome://flags into the address bar and hit Enter. You’ll see a list of system flags and a search bar; type “AI” into that search bar. This will filter the massive list down to about a dozen AI features (and a few other settings where those letters just happen to appear in a longer word). The second search term you’ll need in this window is “Gemini“.
After reviewing the options, you can disable the unwanted AI features — or just turn them all off — but the bare minimum should include:
AI Mode Omnibox entrypoint
AI Entrypoint Disabled on User Input
Omnibox Allow AI Mode Matches
Prompt API for Gemini Nano
Prompt API for Gemini Nano with Multimodal Input
Set all of these to Disabled.
How to disable AI features in Firefox
While Firefox doesn’t have its own built-in chatbots and hasn’t (yet) tried to force upon users agent-based features, the browser does come equipped with smart-tab grouping, a sidebar for chatbots, and a few other perks. Generally, AI in Firefox is much less “in your face” than in Chrome or Edge. But if you still want to pull the plug, you’ve two ways to do it.
The first method is available in recent Firefox releases — starting with version 148, a dedicated AI Controls section appeared in the browser settings, though the controls are currently a bit sparse. You can use a single toggle to completely Block AI enhancements, shutting down AI features entirely. You can also specify whether you want to use On-device AI by downloading small local models (currently just for translations) and configure AI chatbot providers in sidebar, choosing between Anthropic Claude, ChatGPT, Copilot, Google Gemini, and Le Chat Mistral.
The second path — for older versions of Firefox — requires a trip into the hidden system settings. Type about:config into the address bar, hit Enter, and click the button to confirm that you accept the risk of poking around under the hood.
A massive list of settings will appear along with a search bar. Type “ML” to filter for settings related to machine learning.
To disable AI in Firefox, toggle the browser.ml.enabled setting to false. This should disable all AI features across the board, but community forums suggest this isn’t always enough to do the trick. For a scorched-earth approach, set the following parameters to false (or selectively keep only what you need):
ml.chat.enabled
ml.linkPreview.enabled
ml.pageAssist.enabled
ml.smartAssist.enabled
ml.enabled
ai.control.translations
tabs.groups.smart.enabled
urlbar.quicksuggest.mlEnabled
This will kill off chatbot integrations, AI-generated link descriptions, assistants and extensions, local translation of websites, tab grouping, and other AI-driven features.
How to disable AI features in Microsoft apps
Microsoft has managed to bake AI into almost every single one of its products, and turning it off is often no easy task — especially since the AI sometimes has a habit of resurrecting itself without your involvement.
How to disable AI features in Edge
Microsoft’s browser is packed with AI features, ranging from Copilot to automated search. To shut them down, follow the same logic as with Chrome: type edge://flags into the Edge address bar, hit Enter, then type “AI” or “Copilot” into the search box. From there, you can toggle off the unwanted AI features, such as:
Enable Compose (AI-writing) on the web
Edge Copilot Mode
Edge History AI
Another way to ditch Copilot is to enter edge://settings/appearance/copilotAndSidebar into the address bar. Here, you can customize the look of the Copilot sidebar and tweak personalization options for results and notifications. Don’t forget to peek into the Copilot section under App-specific settings — you’ll find some additional controls tucked away there.
How to disable Microsoft Copilot
Microsoft Copilot comes in two flavors: as a component of Windows (Microsoft Copilot), and as part of the Office suite (Microsoft 365 Copilot). Their functions are similar, but you’ll have to disable one or both depending on exactly what the Redmond engineers decided to shove onto your machine.
The simplest thing you can do is just uninstall the app entirely. Right-click the Copilot entry in the Start menu and select Uninstall. If that option isn’t there, head over to your installed apps list (Start → Settings → Apps) and uninstall Copilot from there.
In certain builds of Windows 11, Copilot is baked directly into the OS, so a simple uninstall might not work. In that case, you can toggle it off via the settings: Start → Settings → Personalization → Taskbar→ turn off Copilot.
If you ever have a change of heart, you can always reinstall Copilot from the Microsoft Store.
It’s worth noting that many users have complained about Copilot automatically reinstalling itself, so you might want to do a weekly check for a couple of months to make sure it hasn’t staged a comeback. For those who are comfortable tinkering with the System Registry (and understand the consequences), you can follow this detailed guide to prevent Copilot’s silent resurrection by disabling the SilentInstalledAppsEnabled flag and adding/enabling the TurnOffWindowsCopilot parameter.
How to disable Microsoft Recall
The Microsoft Recall feature, first introduced in 2024, works by constantly taking screenshots of your computer screen and having a neural network analyze them. All that extracted information is dumped into a database, which you can then search using an AI assistant. We’ve previously written in detail about the massive security risks Microsoft Recall poses.
Under pressure from cybersecurity experts, Microsoft was forced to push the launch of this feature from 2024 to 2025, significantly beefing up the protection of the stored data. However, the core of Recall remains the same: your computer still remembers your every move by constantly snapping screenshots and OCR-ing the content. And while the feature is no longer enabled by default, it’s absolutely worth checking to make sure it hasn’t been activated on your machine.
To check, head to the settings: Start → Settings → Privacy & Security →Recall & snapshots. Ensure the Save snapshots toggle is turned off, and click Delete snapshots to wipe any previously collected data, just in case.
How to disable AI in Notepad and Windows context actions
AI has seeped into every corner of Windows, even into File Explorer and Notepad. You might even trigger AI features just by accidentally highlighting text in an app — a feature Microsoft calls “AI Actions”. To shut this down, head to Start → Settings → Privacy & Security → Click to Do.
Notepad has received its own special Copilot treatment, so you’ll need to disable AI there separately. Open the Notepad settings, find the AI features section, and toggle Copilot off.
Finally, Microsoft has even managed to bake Copilot into Paint. Unfortunately, as of right now, there is no official way to disable the AI features within the Paint app itself.
How to disable AI in WhatsApp
In several regions, WhatsApp users have started seeing typical AI additions like suggested replies, AI message summaries, and a brand-new Chat with Meta AI button. While Meta claims the first two features process data locally on your device and don’t ship your chats off to their servers, verifying that is no small feat. Luckily, turning them off is straightforward.
To disable Suggested Replies, go to Settings → Chats → Suggestions & smart replies and toggle off Suggested replies. You can also kill off AI Sticker suggestions in that same menu. As for the AI message summaries, those are managed in a different location: Settings → Notifications → AI message summaries.
How to disable AI on Android
Given the sheer variety of manufacturers and Android flavors, there’s no one-size-fits-all instruction manual for every single phone. Today, we’ll focus on killing off Google’s AI services — but if you’re using a device from Samsung, Xiaomi, or others, don’t forget to check your specific manufacturer’s AI settings. Just a heads-up: fully scrubbing every trace of AI might be a tall order — if it’s even possible at all.
In Google Messages, the AI features are tucked away in the settings: tap your account picture, select Messages settings, then Gemini in Messages, and toggle the assistant off.
Broadly speaking, the Gemini chatbot is a standalone app that you can uninstall by heading to your phone’s settings and selecting Apps. However, given Google’s master plan to replace the long-standing Google Assistant with Gemini, uninstalling it might become difficult — or even impossible — down the road.
If you can’t completely uninstall Gemini, head into the app to kill its features manually. Tap your profile icon, select Gemini Apps activity, and then choose Turn off or Turn off and delete activity. Next, tap the profile icon again and go to the Connected Apps setting (it may be hiding under the Personal Intelligence setting). From here, you should disable all the apps where you don’t want Gemini poking its nose in.
Apple’s platform-level AI features, collectively known as Apple Intelligence, are refreshingly straightforward to disable. In your settings — on desktops, smartphones, and tablets alike — simply look for the section labeled Apple Intelligence & Siri. By the way, depending on your region and the language you’ve selected for your OS and Siri, Apple Intelligence might not even be available to you yet.

Apple has released security updates for iPhones, iPads, Macs, Apple Watches, Apple TVs, and Safari, fixing, in particular, a zero-day flaw that is actively exploited in targeted attacks.
Exploiting this zero-day flaw would allow cybercriminals to run any code they want on the affected device, potentially installing spyware or backdoors without the owner noticing.
Installing these updates as soon as possible keeps your personal information—and everything else on your Apple devices—safe from such an attack.
CVE-2026-20700
The zero-day vulnerability tracked as CVE-2026-20700, is a memory corruption issue in versions before watchOS 26.3, tvOS 26.3, macOS Tahoe 26.3, visionOS 26.3, iOS 26.3 and iPadOS 26.3. An attacker with memory write capability may be able to execute arbitrary code.
Apple says the vulnerability was used as part of an infection chain combined with CVE-2025-14174 and CVE-2025-43529 against devices running iOS versions prior to iOS 26.
Those two vulnerabilities were already patched in the December 2025 update.
Updates for your particular device

If an update appears, tap Download and Install.
Enter your iPhone passcode or Apple ID password if prompted.
Your Apple Watch will automatically restart during the update process. Make sure it remains near your iPhone and on charge until the update completes.
How to update Apple TV
Turn on your Apple TV and make sure it’s connected to the internet, then:
Open the Settings app on Apple TV.
Navigate to System > Software Updates.
Select Update Software.
If an update appears, select Download and Install.
The Apple TV will download the update and restart as needed. Keep your device connected to power and Wi-Fi until the process finishes.
How to update your Safari browser
Safari updates are included with macOS updates, so installing the latest version of macOS will also update Safari. To check manually:
Open the Apple menu > System Settings > General > Software Update.
If you see a Safari update listed separately, click Update Now to install it.
Restart your Mac when prompted.
If you’re on an older macOS version that’s still supported (like Sonoma or Sequoia), Apple may offer Safari updates independently through Software Update.
More advice to stay safe
The most important fix—however inconvenient it may be—is to upgrade to iOS 26.3 (or the latest available version for your device). Not doing so means missing an accumulating list of security fixes, leaving your device vulnerable to newly found vulnerabilities.
Apple has released security updates for iPhones, iPads, Macs, Apple Watches, Apple TVs, and Safari, fixing, in particular, a zero-day flaw that is actively exploited in targeted attacks.
Exploiting this zero-day flaw would allow cybercriminals to run any code they want on the affected device, potentially installing spyware or backdoors without the owner noticing.
Installing these updates as soon as possible keeps your personal information—and everything else on your Apple devices—safe from such an attack.
CVE-2026-20700
The zero-day vulnerability tracked as CVE-2026-20700, is a memory corruption issue in versions before watchOS 26.3, tvOS 26.3, macOS Tahoe 26.3, visionOS 26.3, iOS 26.3 and iPadOS 26.3. An attacker with memory write capability may be able to execute arbitrary code.
Apple says the vulnerability was used as part of an infection chain combined with CVE-2025-14174 and CVE-2025-43529 against devices running iOS versions prior to iOS 26.
Those two vulnerabilities were already patched in the December 2025 update.
Updates for your particular device
The table below shows which updates are available and points you to the relevant security content for that operating system (OS).
iPhone 11 and later, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 8th generation and later, and iPad mini 5th generation and later
For iOS and iPadOS users, here’s how to check if you’re using the latest software version:
Go to Settings > General > Software Update. You will see if there are updates available and be guided through installing them.
Turn on Automatic Updates if you haven’t already—you’ll find it on the same screen.
How to update macOS on any version
To update macOS on any supported Mac, use the Software Update feature, which Apple designed to work consistently across all recent versions. Here are the steps:
Click the Apple menu in the upper-left corner of your screen.
Choose System Settings (or System Preferences on older versions).
Select General in the sidebar, then click Software Update on the right. On older macOS, just look for Software Update directly.
Your Mac will check for updates automatically. If updates are available, click Update Now (or Upgrade Now for major new versions) and follow the on-screen instructions. Before you upgrade to macOS Tahoe 26, please read these instructions.
Enter your administrator password if prompted, then let your Mac finish the update (it might need to restart during this process).
Make sure your Mac stays plugged in and connected to the internet until the update is done.
How to update Apple Watch
Ensure your iPhone is paired with your Apple Watch and connected to Wi-Fi, then:
Keep your Apple Watch on its charger and close to your iPhone.
Open the Watch app on your iPhone.
Tap General > Software Update.
If an update appears, tap Download and Install.
Enter your iPhone passcode or Apple ID password if prompted.
Your Apple Watch will automatically restart during the update process. Make sure it remains near your iPhone and on charge until the update completes.
How to update Apple TV
Turn on your Apple TV and make sure it’s connected to the internet, then:
Open the Settings app on Apple TV.
Navigate to System > Software Updates.
Select Update Software.
If an update appears, select Download and Install.
The Apple TV will download the update and restart as needed. Keep your device connected to power and Wi-Fi until the process finishes.
How to update your Safari browser
Safari updates are included with macOS updates, so installing the latest version of macOS will also update Safari. To check manually:
Open the Apple menu > System Settings > General > Software Update.
If you see a Safari update listed separately, click Update Now to install it.
Restart your Mac when prompted.
If you’re on an older macOS version that’s still supported (like Sonoma or Sequoia), Apple may offer Safari updates independently through Software Update.
More advice to stay safe
The most important fix—however inconvenient it may be—is to upgrade to iOS 26.3 (or the latest available version for your device). Not doing so means missing an accumulating list of security fixes, leaving your device vulnerable to newly found vulnerabilities.
