WhatsApp is quietly rolling out a new safety layer for photos, videos, and documents, and it lives entirely under the hood. It won’t change how you chat, but it will change what happens to the files that move through your chats—especially the kind that can hide malware.
The new feature, called Strict Account Settings, is rolling out gradually over the coming weeks. To see whether you have the option—and to enable it—go to Settings > Privacy > Advanced.
Yesterday, we wrote about a WhatsApp bug on Android that made headlines because a malicious media file in a group chat could be downloaded and used as an attack vector without you tapping anything. You only had to be added to a new group to be exposed to the booby-trapped file. That issue highlighted something security folks have worried about for years: media files are a great vehicle for attacks, and they do not always exploit WhatsApp itself, but bugs in the operating system or its media libraries.
In Meta’s explanation of the new technology, it points back to the 2015 Stagefright Android vulnerability, where simply processing a malicious video could compromise a device. Back then, WhatsApp worked around the issue by teaching its media library to spot broken MP4 files that could trigger those OS bugs, buying users protection even if their phones were not fully patched.
What’s new is that WhatsApp has now rebuilt its core media-handling library in Rust, a memory-safe programming language. This helps eliminate several types of memory bugs that often lead to serious security problems. In the process, it replaced about 160,000 lines of older C++ code with roughly 90,000 lines of Rust, and rolled the new library out to billions of devices across Android, iOS, desktop apps, wearables, and the web.
On top of that, WhatsApp has bundled a series of checks into an internal system it calls “Kaleidoscope.” This system inspects incoming files for structural oddities, flags higher‑risk formats like PDFs with embedded content or scripts, detects when a file pretends to be something it’s not (for example, a renamed executable), and marks known dangerous file types for special handling in the app. It won’t catch every attack, but it should prevent malicious files from poking at more fragile parts of your device.
For everyday users, the Rust rebuilt and Kaleidoscope checks are good news. They add a strong, invisible safety net around photos, videos and other files you receive, including in group chats where the recent bug could be abused. They also line up neatly with our earlier advice to turn off automatic media downloads or use Advanced Privacy Mode, which limits how far a malicious file can travel on your device even if it lands in WhatsApp.
WhatsApp is the latest platform to roll out enhanced protections for users: Apple introduced Lockdown Mode in 2022, and Android followed with Advanced Protection Mode last year. WhatsApp’s new Strict Account Settings takes a similar high-level approach, applying more restrictive defaults within the app, including blocking attachments and media from unknown senders.
However, this is no reason to rush back to WhatsApp, or to treat these changes as a guarantee of safety. At the very least, Meta is showing that it is willing to invest in making WhatsApp more secure.

WhatsApp is going through a rough patch. Some users would argue it has been ever since Meta acquired the once widely trusted messaging platform. User sentiment has shifted from “trusted default messenger” to a grudgingly necessary Meta product.
Privacy-aware users still see WhatsApp as one of the more secure mass-market messaging platforms if you lock down its settings. Even then, many remain uneasy about Meta’s broader ecosystem, and wish all their contacts would switch to a more secure platform.
Back to current affairs, which will only reinforce that sentiment.
Google’s Project Zero has just disclosed a WhatsApp vulnerability where a malicious media file, sent into a newly created group chat, can be automatically downloaded and used as an attack vector.
The bug affects WhatsApp on Android and involves zero‑click media downloads in group chats. You can be attacked simply by being added to a group and having a malicious file sent to you.
According to Project Zero, the attack is most likely to be used in targeted campaigns, since the attacker needs to know or guess at least one contact. While focused, it is relatively easy to repeat once an attacker has a likely target list.
And to put a cherry on top for WhatsApp’s competitors, a potentially even more serious concern for the popular messaging platform, an international group of plaintiffs sued Meta Platforms, alleging the WhatsApp owner can store, analyze, and access virtually all of users’ private communications, despite WhatsApp’s end-to-end encryption claims.
Reportedly, Meta pushed a server change on November 11, 2025, but Google says that only partially resolved the issue. So, Meta is working on a comprehensive fix.
Google’s advice is to disable Automatic Download or enable WhatsApp’s Advanced Privacy Mode so that media is not automatically downloaded to your phone.
And you’ll need to keep WhatsApp updated to get the latest patches, which is true for any app and for Android itself.
Goal: ensure that no photos, videos, audio, or documents are pulled to the device without an explicit decision.
Doing this directly implements Project Zero’s guidance to “disable Automatic Download” so that malicious media can’t silently land on your storage as soon as you are dropped into a hostile group.
Even if WhatsApp still downloads some content, you can stop it from leaking into shared storage where other apps and system components see it.
WhatsApp is a sandbox, and should contain the threat. Which means, keeping media inside WhatsApp makes it harder for a malicious file to be processed by other, possibly more vulnerable components.
The attack chain requires the attacker to add you and one of your contacts to a new group. Reducing who can do that lowers risk.
Read this guide for Android and iOS to learn how to do that.

WhisperPair is a set of attacks that lets an attacker hijack many popular Bluetooth audio accessories that use Google Fast Pair and, in some cases, even track their location via Google’s Find Hub network—all without requiring any user interaction.
Researchers at the Belgian University of Leuven revealed a collection of vulnerabilities they found in audio accessories that use Google’s Fast Pair protocol. The affected accessories are sold by 10 different companies: Sony, Jabra, JBL, Marshall, Xiaomi, Nothing, OnePlus, Soundcore, Logitech, and Google itself.
Google Fast Pair is a feature that makes pairing Bluetooth earbuds, headphones and similar accessories with Android devices quick and seamless, and syncs them across a user’s Google account.
The Google Fast Pair Service (GFPS) utilizes Bluetooth Low Energy (BLE) to discover nearby Bluetooth devices. Many big-name audio brands use Fast Pair in their flagship products, so the potential attack surface consists of hundreds of millions of devices.
The weakness lies in the fact that Fast Pair skips checking whether a device is in pairing mode. As a result, a device controlled by an attacker, such as a laptop, can trigger Fast Pair even when the earbuds are sitting in a user’s ear or pocket, then quickly complete a normal Bluetooth pairing and take full control.
What that control enables depends on the capabilities of the hijacked device. This can range from playing disturbing noises to recording audio via built-in microphones.
It gets worse if the attacker is the first to pair the accessory with an Android device. In that case, the attacker’s Owner Account Key–designating their Google account as the legitimate owner’s—to the accessory. If the Fast Pair accessory also supports Google’s Find Hub network, which many people use to locate lost items, the attacker may then be able to track the accessory’s location.
Google classified this vulnerability, tracked under CVE‑2025‑36911, as critical. However, the only real fix is a firmware or software update from the accessory manufacturer, so users need to check with their specific brand and install accessory updates, as updating the phone alone does not fix the issue.
To find out whether your device is vulnerable, the researchers published a list and recommend keeping all accessories updated. The research team tested 25 commercial devices from 16 manufacturers using 17 different Bluetooth chipsets. They were able to take over the connection and eavesdrop on the microphone on 68% of the tested devices.
These are the devices the researchers found to be vulnerable, but it’s possible that others are affected as well:

If you were still questioning whether iOS 26+ is for you, now is the time to make that call.
Why?
On December 12, 2025, Apple patched two WebKit zero‑day vulnerabilities linked to mercenary spyware and is now effectively pushing iPhone 11 and newer users toward iOS 26+, because that’s where the fixes and new memory protections live. These vulnerabilities were primarily used in highly targeted attacks, but such campaigns are likely to expand over time.
WebKit powers the Safari browser and many other iOS applications, so it’s a big attack surface to leave exposed and isn’t limited to “risky” behavior. These vulnerabilities allowed an attacker to execute arbitrary code on a device after exploitation via malicious web content.
Apple has confirmed that attackers are already exploiting these vulnerabilities in the wild, making installation of the update a high‑priority security task for every user. Campaigns that start with diplomats, journalists, or executives often lead to tooling and exploits leaking or being repurposed, so “I’m not a target” is not a viable safety strategy.
Due to public resistance to new features like Liquid Glass, many iPhone users have not yet upgraded to iOS 26.2. Reports suggest adoption of iOS 26 has been unusually slow. As of January 2026, only about 4.6% of active iPhones are on iOS 26.2, and roughly 16% are on any version of iOS 26, leaving the vast majority on older releases such as iOS 18.
However, Apple only ships these fixes and newer protections, such as Memory Integrity Enforcement, on iOS 26+ for supported devices. Users on older, unsupported devices won’t be able to access these protections at all.
Another important factor in the upgrade cycle is restarting the device. What many people don’t realize is that when you restart your device, any memory-resident malware is flushed—unless it has somehow gained persistence, in which case it will return. High-end spyware tools tend to avoid leaving traces needed for persistence and often rely on users not restarting their devices.
Upgrading requires a restart, which makes this a win-win: you get the latest protections, and any memory-resident malware is flushed at the same time.
For iOS and iPadOS users, you can check if you’re using the latest software version, go 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.
The most important fix—however painful you may find it—is to upgrade to iOS 26.2. Not doing means missing an accumulating list of security fixes, leaving your device vulnerable to more and more newly found vulnerabilities.

Reportedly, pcTattletale founder Bryan Fleming has pleaded guilty in US federal court to computer hacking, unlawfully selling and advertising spyware, and conspiracy.
This is good news not just because we despise stalkerware like pcTattletale, but because it is only the second US federal stalkerware prosecution in a decade. It could could open the door to further cases against people who develop, sell, or promote similar tools.
In 2021, we reported that “employee and child-monitoring” software vendor pcTattletale had not been very careful about securing the screenshots it secretly captured from victims’ phones. A security researcher testing a trial version discovered that the app uploaded screenshots to an unsecured online database, meaning anyone could view them without authentication, such as a username and password.
In 2024, we revisited the app after researchers found it was once again leaking a database containing victim screenshots. One researcher discovered that pcTattletale’s Application Programming Interface (API) allowed anyone to access the most recent screen capture recorded from any device on which the spyware is installed. Another researcher uncovered a separate vulnerability that granted full access to the app’s backend infrastructure. That access allowed them to deface the website and steal AWS credentials, which turned out to be shared across all devices. As a result, the researcher obtained data about both victims and the customers who were doing the tracking.
This is no longer possible. Not because the developers fixed the problems, but because Amazon locked pcTattletale’s entire AWS infrastructure. Fleming later abandoned the product and deleted the contents of its servers.
However, Homeland Security Investigations had already started investigating pcTattletale in June 2021 and did not stop. A few things made Fleming stand out among other stalkerware operators. While many hide behind overseas shell companies, Fleming appeared to be proud of his work. And while others market their products as parental control or employee monitoring tools, pcTattletale explicitly promoted spying on romantic partners and spouses, using phrases such as “catch a cheater” and “surreptitiously spying on spouses and partners.” This made it clear the software was designed for non-consensual surveillance of adults.
Fleming is expected to be sentenced later this year.
Malwarebytes, as one of the founding members of the Coalition Against Stalkerware, makes it a priority to detect and remove stalkerware-type apps from your device.
It is important to keep in mind, however, that removing stalkerware may alert the person spying on you that the app has been discovered. The Coalition Against Stalkerware outlines additional steps and considerations to help you decide the safest next move.
Because the apps often install under different names and hide themselves from users, they can be difficult to find and remove. That is where Malwarebytes can help you.
To scan your device:
The scan may take a few minutes.
If malware is detected, you can choose one of the following actions:

Executive Summary The OPCOPRO “Truman Show” operation is a fully synthetic, AI‑powered investment scam that uses legitimate Android and iOS apps from the official mobile app stores, and AI‑generated communities to steal money and identity data from victims. Instead of relying on malicious code, the attackers use social engineering. The attackers pull victims using phishing SMS/ads/Telegram into tightly-controlled WhatsApp and Telegram groups, where AI‑generated “experts” and synthetic peers simulate an institutional‑grade trading community for weeks before any money or personal details are requested. The mobile apps themselves contain no trading logic and act only as WebView shells connected to attacker‑controlled […]

This blog is part of a series highlighting new and concerning trends we noticed over the last year. Trends matter because they almost always provide a good indication of what’s coming next.
If there’s one thing that became very clear in 2025, it’s that malware is no longer focused on Windows alone. We’ve seen some major developments, especially in campaigns targeting Android and macOS. Unfortunately, many people still don’t realize that protecting smartphones, tablets, and other connected devices is just as essential as securing their laptops.
Banking Trojans on Android are not new, but their level of sophistication continues to rise. These threats continue to be a major problem in 2025, often disguising themselves as fake apps to steal credentials or stealthily take over devices. A recent wave of advanced banking Trojans, such as Herodotus, can mimic human typing behaviors to evade detection, highlighting just how refined these attacks have become. Android malware also includes adware that aggressively pushes intrusive ads through free apps, degrading both the user experience and overall security.
Several Trojans were found to use overlays, which are fake login screens appearing on top of real banking and cryptocurrency apps. They can read what’s on the screen, so when someone enters their username and password, the malware steals them.
One of the most notable developments for Mac users was the expansion of the notorious ClickFix campaign to macOS. Early in 2025, I described how criminals used fake CAPTCHA sites and a clipboard hijacker to provide instructions that led visitors ro infect their own machines with the Lumma infostealer.
ClickFix is the name researchers have since given to this type of campaign, where users are tricked into running malicious commands themselves. On macOS, this technique is being used to distribute both AMOS stealers and the Rhadamanthys infostealer.
Malware developers increasingly use cross-platform languages such as Rust and Go to create malware that can run on Windows, macOS, Linux, mobile, and even Internet of Things (IoT) devices. This enables flexible targeting and expands the number of potential victims. Malware-as-a-Service (MaaS) models are on the rise, offering these tools for rent or purchase on underground markets, further professionalizing malware development and distribution.
iPhone users have been found to be more prone to scams and less conscious about mobile security than Android owners. That brings us to the first line of defense, which has nothing to do with the device or operating system you use: education.
Social engineering exploits human behavior, and knowing what to look out for makes you far less likely to fall for a scam.
Fake apps that turn out to be malware, malicious apps in the Play Store, sextortion, and costly romance scams all prey on basic human emotions. They either go straight for the money or deliver Trojan droppers as the first step toward infecting a device.
We’ve also seen consistent growth in Remote Access Trojan (RAT) activity, often used as an initial infection method. There’s also been a rise in finance-focused attacks, including cryptocurrency and banking-related targets, alongside widespread stealer malware driving data breaches.
Taken together, these trends point to a clear shift. Cybercriminals are increasingly focusing on operating systems beyond Windows, combining advanced techniques and social engineering tailored specifically to mobile and macOS.

We’ve also seen consistent growth in Remote Access Trojan (RAT) activity, often used as an initial infection method. There’s also been a rise in finance-focused attacks, including cryptocurrency and banking-related targets, alongside widespread stealer malware driving data breaches.
Taken together, these trends point to a clear shift. Cybercriminals are increasingly focusing on operating systems beyond Windows, combining advanced techniques and social engineering tailored specifically to mobile and macOS.

China-based phishing groups blamed for non-stop scam SMS messages about a supposed wayward package or unpaid toll fee are promoting a new offering, just in time for the holiday shopping season: Phishing kits for mass-creating fake but convincing e-commerce websites that convert customer payment card data into mobile wallets from Apple and Google. Experts say these same phishing groups also are now using SMS lures that promise unclaimed tax refunds and mobile rewards points.
Over the past week, thousands of domain names were registered for scam websites that purport to offer T-Mobile customers the opportunity to claim a large number of rewards points. The phishing domains are being promoted by scam messages sent via Apple’s iMessage service or the functionally equivalent RCS messaging service built into Google phones.
An instant message spoofing T-Mobile says the recipient is eligible to claim thousands of rewards points.
The website scanning service urlscan.io shows thousands of these phishing domains have been deployed in just the past few days alone. The phishing websites will only load if the recipient visits with a mobile device, and they ask for the visitor’s name, address, phone number and payment card data to claim the points.

If card data is submitted, the site will then prompt the user to share a one-time code sent via SMS by their financial institution. In reality, the bank is sending the code because the fraudsters have just attempted to enroll the victim’s phished card details in a mobile wallet from Apple or Google. If the victim also provides that one-time code, the phishers can then link the victim’s card to a mobile device that they physically control.

Ford Merrill works in security research at SecAlliance, a CSIS Security Group company. Merrill said multiple China-based cybercriminal groups that sell phishing-as-a-service platforms have been using the mobile points lure for some time, but the scam has only recently been pointed at consumers in the United States.
“These points redemption schemes have not been very popular in the U.S., but have been in other geographies like EU and Asia for a while now,” Merrill said.
A review of other domains flagged by urlscan.io as tied to this Chinese SMS phishing syndicate shows they are also spoofing U.S. state tax authorities, telling recipients they have an unclaimed tax refund. Again, the goal is to phish the user’s payment card information and one-time code.

Many SMS phishing or “smishing” domains are quickly flagged by browser makers as malicious. But Merrill said one burgeoning area of growth for these phishing kits — fake e-commerce shops — can be far harder to spot because they do not call attention to themselves by spamming the entire world.
Merrill said the same Chinese phishing kits used to blast out package redelivery message scams are equipped with modules that make it simple to quickly deploy a fleet of fake but convincing e-commerce storefronts. Those phony stores are typically advertised on Google and Facebook, and consumers usually end up at them by searching online for deals on specific products.

With these fake e-commerce stores, the customer is supplying their payment card and personal information as part of the normal check-out process, which is then punctuated by a request for a one-time code sent by your financial institution. The fake shopping site claims the code is required by the user’s bank to verify the transaction, but it is sent to the user because the scammers immediately attempt to enroll the supplied card data in a mobile wallet.
According to Merrill, it is only during the check-out process that these fake shops will fetch the malicious code that gives them away as fraudulent, which tends to make it difficult to locate these stores simply by mass-scanning the web. Also, most customers who pay for products through these sites don’t realize they’ve been snookered until weeks later when the purchased item fails to arrive.
“The fake e-commerce sites are tough because a lot of them can fly under the radar,” Merrill said. “They can go months without being shut down, they’re hard to discover, and they generally don’t get flagged by safe browsing tools.”
Happily, reporting these SMS phishing lures and websites is one of the fastest ways to get them properly identified and shut down. Raymond Dijkxhoorn is the CEO and a founding member of SURBL, a widely-used blocklist that flags domains and IP addresses known to be used in unsolicited messages, phishing and malware distribution. SURBL has created a website called smishreport.com that asks users to forward a screenshot of any smishing message(s) received.
“If [a domain is] unlisted, we can find and add the new pattern and kill the rest” of the matching domains, Dijkxhoorn said. “Just make a screenshot and upload. The tool does the rest.”

Merrill said the last few weeks of the calendar year typically see a big uptick in smishing — particularly package redelivery schemes that spoof the U.S. Postal Service or commercial shipping companies.
“Every holiday season there is an explosion in smishing activity,” he said. “Everyone is in a bigger hurry, frantically shopping online, paying less attention than they should, and they’re just in a better mindset to get phished.”
As we can see, adopting a shopping strategy of simply buying from the online merchant with the lowest advertised prices can be a bit like playing Russian Roulette with your wallet. Even people who shop mainly at big-name online stores can get scammed if they’re not wary of too-good-to-be-true offers (think third-party sellers on these platforms).
If you don’t know much about the online merchant that has the item you wish to buy, take a few minutes to investigate its reputation. If you’re buying from an online store that is brand new, the risk that you will get scammed increases significantly. How do you know the lifespan of a site selling that must-have gadget at the lowest price? One easy way to get a quick idea is to run a basic WHOIS search on the site’s domain name. The more recent the site’s “created” date, the more likely it is a phantom store.
If you receive a message warning about a problem with an order or shipment, visit the e-commerce or shipping site directly, and avoid clicking on links or attachments — particularly missives that warn of some dire consequences unless you act quickly. Phishers and malware purveyors typically seize upon some kind of emergency to create a false alarm that often causes recipients to temporarily let their guard down.
But it’s not just outright scammers who can trip up your holiday shopping: Often times, items that are advertised at steeper discounts than other online stores make up for it by charging way more than normal for shipping and handling.
So be careful what you agree to: Check to make sure you know how long the item will take to be shipped, and that you understand the store’s return policies. Also, keep an eye out for hidden surcharges, and be wary of blithely clicking “ok” during the checkout process.
Most importantly, keep a close eye on your monthly statements. If I were a fraudster, I’d most definitely wait until the holidays to cram through a bunch of unauthorized charges on stolen cards, so that the bogus purchases would get buried amid a flurry of other legitimate transactions. That’s why it’s key to closely review your credit card bill and to quickly dispute any charges you didn’t authorize.
