Those losses stem from 22,364 AI-related complaints. And these figures represent only the reported losses, which may well be the proverbial tip of the iceberg.
The main drivers behind the rise in AI-powered scams are voice cloning, deepfake images and videos, and AI‑generated scripts. These tools have supercharged classic fraud schemes such as romance scams, kidnapping and extortion calls, fake influencers, and government impersonation.
Michael Machtinger, deputy assistant director of the FBI Cyber Division, told the Wall Street Journal:
“AI-created fraudulent communications can look very official and very legitimate to even the most trained individuals.”
The FBI and financial institutions recommend verifying identities via official contact channels. One of their biggest concerns is government impersonation scams, which have evolved from crude IRS gift‑card phone calls into sophisticated, multi‑channel operations that combine spoofed caller ID, stolen agency logos, and AI‑generated audio and video of public officials.
This report, and others like it, shows how AI is being weaponized to automate research on victims, generate convincing scripts, and create highly believable deepfake personas at scale.
AI is also increasingly used in business email compromise (BEC), romance scams, and impersonation fraud. In BEC cases involving AI, losses have already reached tens of millions of dollars for businesses alone.
For a broader look at why AI is simultaneously fueling scams like these and becoming indispensable to defending against them, see my article AI: Threat, tool, or both?
It explains how both defenders and criminals use AI to find vulnerabilities, and why security vendors increasingly rely on AI to process vast amounts of telemetry, detect anomalies, and keep pace with threats that “no longer move at human speed.”
How to stay safe
Consumer protection agencies have documented a growing list of the ways scammers are using AI to try to rip people off. The main problem is that we can no longer take it at face value that the person we’re talking to is who they claim to be.
Government agencies and financial institutions recommend that you:
Be skeptical of urgent payment demands, especially those involving cryptocurrency or gift cards
Limit the amount of voice and video content you share publicly, as it can be reused by scammers
Report incidents quickly to your bank(s) and IC3.gov

Planning a holiday should be exciting, fun, and not a cybersecurity risk. But booking flights, hotels, and rental properties often means sharing sensitive personal and financial information across multiple platforms. Combined with frequent travel scams and recurring data breaches in the travel and hospitality sector, it creates plenty of opportunities for criminals.
This guide covers the most common risks when making travel reservations and explains how to avoid them. Save the adventure for your destination.
Travel bookings combine high-value payments with urgency and emotional decision-making. Attackers love that for several reasons:
Large upfront payments make scams profitable.
Booking confirmations often contain valuable personal data, such as names, travel dates, contact details, and sometimes passport information.
Travel and hospitality companies are frequent breach targets due to complex IT environments and third-party integrations.
Recent years have seen repeated breaches involving hotel chains, booking platforms, cruise operators, and airlines, exposing everything from email addresses to passport numbers.
Common travel-related scams
Fake booking websites
Attackers create convincing clones of airline, hotel, and travel booking websites, often promoted through online ads or SEO poisoning (manipulating search engine results). Victims enter payment details, receive fake confirmations, and only discover the fraud later.
Emails, texts, or messaging app notifications may claim there’s a problem with your booking and urge you to click a link, open an attachment, or call a number. The scammers often impersonate legitimate travel brands and may include real stolen data from previous breaches.
Earlier this year, we wrote about a Booking.com breach that provided scammers with a lot of useful information that could make their messages appear more convincing.
Vacation rental fraud
Scammers post fake listings or hijack legitimate ones on rental platforms. They typically encourage off-platform communication or payments to avoid built-in protections.
In 2024, one of our researchers encountered exactly this type of scam. A supposedly legitimate Airbnb listing in Amsterdam turned out to be fake, and the scammer sent an email claiming to be from TripAdvisor in an attempt to collect payment details.
“Too good to be true” deals
Deep discounts on flights or accommodation are used to lure victims into paying for offers that don’t exist.
If a deal seems unusually generous, look for the catch. Be especially cautious when advertisers claim the offer will end very soon. Creating urgency is one of the oldest tricks in the scammer playbook.
Booking.com has become an increasingly popular brand for scammers to impersonate. According to our—anonymized—Scam Guard data, we’ve recently seen:
Fake cashback emails promising a €435 refund that lead to phishing websites
In-app messages requesting an additional reservation fee
Emails containing PDF attachments that require a “secure viewer,” which turns out to be malware
WhatsApp messages claiming credit card details are missing and directing users to phishing sites
Text messages linking to fake Booking.com pages and demanding card verification before a deadline
The number of scams impersonating Booking.com has been growing. Since the breach disclosed in April, Scam Guard data shows a 56% increase in Booking.com-related scams compared to the previous period, with weekly volume up consistently across five straight weeks.
How to book travel safely
There are a few simple things that can dramatically reduce your risk:
Use secure payment methods. Credit cards offer better fraud protection than debit cards or bank transfers. Never pay anyone asking for payment in cryptocurrencies or gift cards.
Stick to trusted platforms. Even though these are not guaranteed to be safe, using them is better than gambling on an unknown platform.
Don’t click on sponsored search results. I cannot say this often enough.
Verify the existence of the booked accommodation through other channels.
Treat requests to move communication or payment to another platform as suspicious.
Consider urgent language, unexpected attachments, and mismatched sender domains as red flags.
Downloads needed to open an attachment are not to be trusted. These downloads often turn out to be malware. To block and remove malware, use an up-to-date, real-time anti-malware solution.
Pro tip: Malwarebytes Browser Guard will block known phishing websites and can even recognize suspicious websites that are not in our database yet.

A new batch of fake payment invoices is being staged right now, and we caught the campaign while it was still being put together. The emails impersonate PayPal, Amazon, and Geek Squad, and others, and they all share one goal: to scare you into calling a phone number where a fake “support agent” is waiting.
What makes this wave unusual is that some of the templates we recovered still contained blank fields where the phone number and price should have been, while others were already complete and in circulation. We caught the campaign mid-rollout.
What’s the scam?
If you receive an email that looks like a receipt—“Your subscription renewed for $349,” “You sent a payment of $598.96”—and it tells you to call a number to cancel or dispute the charge, stop.
There is no charge. The email exists to get you on the phone with a scammer who will then try to talk you into handing over remote access to your computer, your card details, or a “refund” that somehow requires you to send them money.
This particular flavor is called a “phantom invoice” or “refund” scam, and the trick is psychological, not technical. That’s why these emails can often slip past spam filters: there’s often no malicious attachment or link for security systems to analyze. The scam is in the phone number you’re urged to call.
If you didn’t make the purchase, there’s no need to call the number in the email to cancel it. Real companies don’t pressure customers into resolving unexpected charges through unsolicited phone numbers.
The goal is simple: create enough concern to get you to call. You see a significant charge you don’t recognize, say $499, and your first instinct is to stop it. The invoice helpfully provides a number to call “if this wasn’t you.” So you call, and now you’re talking to the scammer.
From there, the conversation usually leads to one of a few outcomes. They may ask you to install software so they can “fix” the charge, giving them access to your computer. They may ask for your card or bank details to “process the refund.” Or they may “accidentally” refund too much and ask you to send the difference back, usually by gift card or bank transfer.
The invoice is just the bait, while the phone call is the trap.
These emails are convincing, and some are already reaching inboxes. The good news is that simply receiving one doesn’t put you at risk. The scam only works if it succeeds in getting you to call the number provided. If you recognize the message as fraudulent and delete it, the attack stops there.
If you did call the number and followed instructions from a scammer, run a virus scan and check your bank accounts. Change your critical passwords, enable multi-factor authentication (MFA), and make sure your security software is up to date.
How we caught it half-built
Most scam investigations start after the damage is done. This one was different. We came across a cluster of nearly identical invoice templates that were clearly part of the same kit, and several of them were incomplete.
Where a finished scam email would show a phone number, some of these showed the literal text #TFN# instead, which is just a placeholder. (“TFN” is the scammers’ shorthand for toll-free number, the callback line they route victims to.) Others left the price as #PRICE#, the date as #DATE#, and the recipient as #EMAIL#. These are merge fields—the blanks a bulk-sending tool fills in automatically before a campaign goes out.
Finding those placeholders still in place told us that the operation was still being assembled. Some templates were still half-finished, while others were already complete and carrying live callback numbers. We’d caught the campaign mid-rollout, between being built and fully launched.
Why these invoices look believable
The scammers use familiar brands such as PayPal, Amazon, and Geek Squad. They’re companies people expect to receive receipts and renewal notices from, which lowers suspicion.
The charges are also carefully chosen. Amounts in the few-hundred-dollar range are large enough to cause concern but still seem plausible as a subscription renewal or online purchase.
Many messages add urgency, telling recipients to call quickly to dispute or cancel the charge. This pressure is designed to stop people from verifying the transaction independently.
Some invoices even combine trusted brands, such as claiming a payment was sent through PayPal to Amazon. Referencing multiple well-known companies makes the message appear more credible.
How to spot a fake invoice
The good news is that these scams share warning signs. Once you know what to look for, they get a lot easier to catch. Watch for any of these:
A charge you don’t remember making. If you don’t recognize the charge, verify it independently through your account or bank. If there’s no record of it, the invoice is likely a lure designed to get you to call.
A ticking clock. “Call within 12 hours,” “cancel before it renews,” or “act immediately” provide fake urgency designed to stop you thinking. Real billing problems can wait while you check.
Brands you trust, used as cover. The more familiar the logo, the less carefully people read. Scammers borrow trust they didn’t earn.
Odd details that don’t quite fit. A PayPal email “from” Amazon, a stray address that belongs to no one, or slightly off wording. Trust the small things that feel wrong.
Pressure to keep you on the phone. Once you call, a real company would never stop you from hanging up to verify, but a scammer will.
If even one of these is present, treat the whole message as suspicious.
Remember the single rule that defeats this entire scam: A genuine company will never rush you onto a call to undo a payment you never made. If you’re not sure whether a charge is real, close the email and check your account the normal way: by typing the company’s website into your browser yourself, or calling the number on the back of your bank card.

What to do if one of these lands in your inbox
If you receive a suspicious invoice like the ones described here, take a few simple precautions:
Don’t call the number. That’s the core of the scam. Legitimate refunds or cancellations don’t require you to call a number from an unsolicited receipt.
Don’t reply or click anything. Treat the message as suspicious, even if it looks legitimate.
Verify charges independently. If you’re concerned a charge might be real, log in directly to PayPal, your bank, or the retailer by typing the address yourself and reviewing your transaction history.
Report it. Forward suspected phishing emails to the impersonated company’s abuse address and, in the US, report them to the FTC at reportfraud.ftc.gov. Reporting helps disrupt scam operations.
If you already called, end the conversation. Don’t install any software they recommend. If you granted remote access or shared payment information, contact your bank immediately and run a trusted security scan on your device.
Be wary of urgency. Phrases like “within 12 hours” or “cancel now” are designed to pressure you into acting before you think. Take the time to verify the claim independently.
Scammers are increasingly shifting to tactics that software can’t easily inspect. A phone number in an email is difficult for security tools to evaluate, and the actual scam happens over a phone call instead of through a malicious link or attachment.
That’s why finding this campaign during rollout matters. Instead of seeing the damage afterward, we got a look at the preparation: unfinished templates, incomplete details, and the scam kit before it was fully deployed.
The best defense is simple: if an unexpected invoice tells you to call a number immediately, stop and verify the charge independently first.

Have you ever gotten a phone call and had a gut feeling that those random digits looked extra suspicious? It happens to millions of people every day. While many people have trained themselves to ignore such calls, they still pose a threat across the US. In fact, scammers stole more than $21 billion from Americans last year, according to the latest IC3 report.
That’s why we created Scam Number Check.
Now, instead of risking a call with a scammer, you can look up a number and get a clear answer in seconds.
How to use Scam Number Check
We know scam calls happen every day, and they can cost victims a lot of money. So we designed Scam Number Check to be really simple to use. It’s free, private, and instant.
If the number looks suspicious, you can choose whether to block or report it. Remember, reporting suspicious numbers helps protect others.
Understanding the results
Scam Number Check can provide one of three verdicts when you check a phone number. Here’s what each means and how you should proceed:
Do not trust this number. Multiple people have flagged this number as a scam. Don’t call back, don’t share personal info, and don’t send money if they ask.
This number seems safe. Based on available data, this number has not been associated with suspicious activity. It is our recommendation that you proceed with caution in this case.
We don’t have enough info. No information is available in the threat intelligence database. This doesn’t mean it’s safe, so proceed with caution.
Why it matters
Scammers like to pile on the pressure and create fake urgency so you don’t have time to think. If you don’t recognize a number, let it go to voicemail first. Then check the number with Scam Number Check to see if it’s been linked to scams or suspicious activity. This simple extra step might help you avoid sharing personal information, sending money, or falling for impersonation scams.
Scams are getting harder to spot every day. By making Malwarebytes even better at catching threats, we’re helping you stay one step ahead of scammers and cybercriminals.

Phishing has changed. Slowly but surely, cybercriminals are turning to infostealers instead.
Traditional phishing hasn’t gone away. Far from it. But many attackers are no longer focused solely on tricking victims into entering usernames and passwords on fake login pages. Instead, they are using infostealers to quietly collect passwords, cookies, browser data, and other sensitive information from infected devices.
This approach is attractive because it scales well and reduces friction. Instead of relying on a victim to type credentials into a fake site, the malware can harvest logins already saved in browsers, session tokens, autofill data, cryptocurrency wallet details, and even files that contain useful information.
This makes the attack chain less visible. A traditional phishing email often leaves obvious clues: a suspicious link, a fake login page, or a strange attachment. Infostealers are different. They can arrive through malicious online ads (malvertising), cracked software, fake browser updates, game cheats, or dubious download sites, and once installed, they work in the background, stealing whatever the victim’s device has in store.
Part of this shift could be due to the widespread adoption of multi-factor authentication (MFA). By stealing session cookies, cybercriminals can bypass MFA, so they can access accounts without needing a password or authentication code.
Another factor is the rise of the malware-as-a-service (MaaS) ecosystem. Infostealers are cheap to deploy, easy to scale, and highly profitable. Rather than building a full attack chain themselves, many criminals buy access to ready-made stealer kits, loaders, or initial access services from underground vendors. This lowers the barrier to entry and allows less-skilled attackers to run credential theft operations.
In many cases, infostealers are just the first stage of a larger criminal operation. The stolen data is collected, packaged, and sold to other criminals interested in the harvested information. These buyers may specialize in fraud, account takeover, business email compromise, or ransomware. A single infected machine can generate multiple revenue streams: credentials for one buyer, session cookies for another, and corporate access or wallet data for a third.
That division of labor is one reason infostealers have become so persistent. Operators can update their code, rotate infrastructure, and launch new campaigns with minimal effort, while affiliates handle distribution through phishing, malvertising, fake downloads, or social media lures.

Because infostealers commonly arrive through malvertising, fake browser updates, and one-click downloads, it’s worth treating ads and pop-ups with healthy skepticism. My personal tip: Never click on sponsored ads. Instead, visit official websites directly and download software only from trusted sources such as official vendor sites or app stores.
Another increasingly popular technique is ClickFix, a social engineering attack that tricks users into infecting their own devices. Never run commands or scripts copied from websites, emails, or messages unless you trust the source and understand the action’s purpose. If a website tells you to execute a command or perform a technical action, check official documentation or contact support before proceeding.
Pirated software, game cheats, and cracked tools remain some of the most common delivery methods for infostealers. These downloads often come bundled with malware that installs alongside the software you intended to get. The same caution applies to many browser extensions and add-ons that promise extra features or convenience. Stick to extensions from reputable developers, check reviews and permissions carefully, and avoid installing any add-on that asks for more access than it plausibly needs.
Phishing emails are still a major threat, but many can be spotted if you slow down and verify before clicking. Even if an email looks like it comes from a trusted brand, treat unsolicited attachments and links with caution, especially when they urge you to open a file, install something urgently, or fix a billing issue. If you’re unsure, check the sender address, look for typos or odd phrasing, and confirm the request through a separate channel such as the company’s official website rather than the link in the email.

Phishing has changed. Slowly but surely, cybercriminals are turning to infostealers instead.
Traditional phishing hasn’t gone away. Far from it. But many attackers are no longer focused solely on tricking victims into entering usernames and passwords on fake login pages. Instead, they are using infostealers to quietly collect passwords, cookies, browser data, and other sensitive information from infected devices.
This approach is attractive because it scales well and reduces friction. Instead of relying on a victim to type credentials into a fake site, the malware can harvest logins already saved in browsers, session tokens, autofill data, cryptocurrency wallet details, and even files that contain useful information.
This makes the attack chain less visible. A traditional phishing email often leaves obvious clues: a suspicious link, a fake login page, or a strange attachment. Infostealers are different. They can arrive through malicious online ads (malvertising), cracked software, fake browser updates, game cheats, or dubious download sites, and once installed, they work in the background, stealing whatever the victim’s device has in store.
Part of this shift could be due to the widespread adoption of multi-factor authentication (MFA). By stealing session cookies, cybercriminals can bypass MFA, so they can access accounts without needing a password or authentication code.
Another factor is the rise of the malware-as-a-service (MaaS) ecosystem. Infostealers are cheap to deploy, easy to scale, and highly profitable. Rather than building a full attack chain themselves, many criminals buy access to ready-made stealer kits, loaders, or initial access services from underground vendors. This lowers the barrier to entry and allows less-skilled attackers to run credential theft operations.
In many cases, infostealers are just the first stage of a larger criminal operation. The stolen data is collected, packaged, and sold to other criminals interested in the harvested information. These buyers may specialize in fraud, account takeover, business email compromise, or ransomware. A single infected machine can generate multiple revenue streams: credentials for one buyer, session cookies for another, and corporate access or wallet data for a third.
That division of labor is one reason infostealers have become so persistent. Operators can update their code, rotate infrastructure, and launch new campaigns with minimal effort, while affiliates handle distribution through phishing, malvertising, fake downloads, or social media lures.

A new scam is targeting people who publish Chrome extensions.
The scam arrives as an official-looking “copyright removal request” claiming your extension is about to be removed from the Chrome Web Store and that you have 48 hours to appeal.
It even looks personalized. After you enter your extension’s ID to “verify” it, the page pulls in your extension’s real name and icon. But it’s all part of a phishing attack designed to steal your Google username and password.
If attackers gain access to a developer account, they may be able to take over the extension, access developer resources, or potentially push malicious updates to users.
What’s actually going on
If you’ve published a Chrome extension, you might encounter a page that looks like an official Google notice warning that your extension is being removed for copyright infringement.
The page asks you to enter your extension ID, then displays your real extension details alongside a complaint number and countdown clock. It pressures you to sign in with Google to file an appeal before time runs out.
None of it is real. The page is not operated by Google. The complaint, deadline, and countdown are fabricated. The goal is to trick you into entering your Google username and password into a fake sign-in window controlled by the scammer.
The most important rule to remember: Genuine warnings about your extension appear in your Chrome Web Store developer dashboard, not on a third-party website.
Why scammers want developer accounts
Chrome extensions have access to users’ browsers, and they can be updated automatically.
If attackers gain control of a developer account, they may be able to modify an extension, access developer resources, or potentially distribute malicious updates to existing users.
The page is hosted on a domain that has nothing to do with Google. In the version we analyzed, the site used the address dmca-chrome-extensions[.]click.
Despite that, it uses Google’s branding and presents itself as a “Chrome Web Store Developer Policy Center.”
The page first asks for the link or ID of your extension. That seems harmless, which is exactly why it works.
It uses your own extension to look convincing
After you enter your extension ID, the page briefly displays a “Looking up extension…” message and then builds a fake takedown notice around your real extension.
When we tested the scam with Malwarebytes Browser Guard, it displayed our genuine extension name, icon, and Chrome Web Store listing alongside the fake complaint.
The site is simply pulling publicly available information from your extension’s Chrome Web Store page. Anyone can see that information. The scammers use it to make the fake notice appear legitimate.
Everything else is invented.
The complaint number, “date received,” 48-hour deadline, countdown timer, and timeline of events are generated by the scam page itself.
The countdown is there to rush you
A red warning banner claims your extension will be permanently removed unless you act within 48 hours, and a clock counts down by the second. The whole layout pushes you toward one button: sign in with Google to “verify your identity” and file your appeal.
The urgency is designed to create pressure so you react before taking the time to verify the claim.
The fake sign-in window
When you click “Continue to verification,” a Google sign-in window appears with a title bar, padlock, and address showing accounts.google.com.
It looks authentic, but it isn’t.
The “window” is actually part of the web page itself. The padlock and address are just graphics designed to look like a real browser window.
The scammers even tailor the appearance to match your operating system, showing Mac-style windows on macOS and Windows-style windows on Windows devices.
Anything typed into this fake sign-in form is sent directly to the scammers.
One giveaway is that the window cannot leave the browser page. Try dragging it to the edge of your screen and it stops at the browser border. Minimize the browser and it disappears as well.
Most importantly, your browser’s real address bar still shows the scam site’s address, not Google’s.
How to stay safe
The good news is that a few simple habits defeat this scam.
Don’t trust the link. If you receive a warning about your extension, go directly to your Chrome Web Store developer dashboard and check there.
Be suspicious of urgency. Legitimate policy processes don’t rely on countdown clocks to force immediate action.
Check the address bar. A real Google sign-in page appears at accounts.google.com in your browser’s actual address bar.
Test the window. If a sign-in window can’t be dragged outside the browser or disappears when the browser is minimized, it’s probably fake.
Turn on stronger sign-in protection. Passkeys and hardware security keys make stolen passwords far less useful to attackers.
Use security software with phishing and web protection. Our Browser Guard, which is also part of Malwarebytes Premium can help block malicious websites and phishing pages before you enter sensitive information.
This isn’t a crude phishing page. It uses your real extension details, mimics Google’s branding, and creates a convincing sense of urgency.
If you receive a warning about your extension, don’t follow the link and don’t race the countdown. Go directly to your Chrome Web Store developer dashboard and verify the claim there.
When in doubt, close the tab.
If you already entered your details
Act quickly.
Change your Google password immediately from a trusted device.
Sign out of all active sessions in your Google account security settings.
Review connected apps and devices for anything unfamiliar.
Turn on two-step verification, preferably using a passkey or security key.
Check your Chrome Web Store listings for changes, uploads, or new versions you didn’t publish.

Sometimes it happens. You’re happily playing a game on your phone or laptop when suddenly alarms pop up out of nowhere:
“Your device is infected!”
“Your iCloud is full!”
“Your account is restricted for watching porn!”
Some games can be played for free if you agree to watch ads, and in others you can get extra lives, perks, or boosters by watching ads. That’s fine, as long as you’re given a choice and the ads are legitimate.
Unfortunately, cybercriminals sometimes manage to buy advertising space and use it to defraud gamers.
Let’s look at some examples.
The iCloud storage scam, or its OneDrive equivalent, is a well-known and long-running scam that claims you need to expand your storage or all your files will be deleted. The websites these messages link to come in many forms, but they all ask for personal and payment details to complete the upgrade.
“Your account has been restricted. We have detected that your device has been hacked after visiting adult websites. Solution: 1:Click the “OK” button below;
2:You will be redirected to App Store;
3:Install and open the app, then run the cleanup program.”
This ad is a scam and uses a classic scare tactic. It falsely claims your device has been hacked and tries to pressure you into clicking “OK” and installing a cleanup app.
Messages like this sometimes claim to be from your ISP, a “Security Department,” or a generic “Safety Center.”
“Apple Security Alert 8 viruses have been detected on your iPhone. Now iOS is damaged by 72%. Further damage to the system will result in device lockup and loss of all data within two minutes. Please click the button below to remove all viruses.”
This is another fake warning, commonly used by scammers to trick users into clicking links or downloading unnecessary or harmful software. Apple doesn’t send alerts like this, and these messages use vague threats to get your attention.
What kind of app you’re really installing if you follow the instructions depends on your device and your location. If you’re “lucky,” it’s just adware, but you might just as easily end up with an infostealer.
In many cases, you’ll end up with fleeceware, a type of deceptive mobile app where developers lure users in with short free trials that quickly convert into hidden subscription fees, sometimes costing hundreds of dollars per month. These apps often offer some functionality to stay on the barely legal side of things, but at wildly inflated prices.
How to stay safe
The best response to these messages is simply to ignore them.
Real system alerts come from the OS, not from inside a game window or browser tab. Here’s a simple test: If you can switch apps and the “warning” disappears with the browser/game, it was not a system‑level alert.
Check the destination URLs before proceeding. Apple, Google, and major ISPs use predictable domains. A familiar-looking URL is not proof that a message is legitimate, but if the URL looks suspicious, it should definitely be treated as a scam.
You may arrive at something that looks like the official App Store or Google Play Store. Be wary of lookalike app stores and unofficial download sites, but if you are on the real store, the app is generally safer to install. However, it’s still worth checking reviews, permissions, and the developer before proceeding.
Visit the official website of the organization the message claims to be from and log in there. If there’s a genuine problem with your account, storage, or device, you’ll find information about it through official channels.
Use an up-to-date, real-time anti-malware solution on your devices that can detect and block malicious apps.

A fake website impersonating BlueWallet (a real Bitcoin wallet) is targeting Mac users with a simple but effective attack. BlueWallet itself has not been compromised. Instead, cybercriminals have stolen the name and branding of the legitimate Bitcoin wallet to make a malicious download appear trustworthy.
If you went looking for a cryptocurrency wallet and landed on one of these fake BlueWallet download pages, the site tried to trick you into opening a downloaded file in a built-in macOS tool and pressing “Run.” If you followed those instructions, the malware could steal saved passwords, browser logins, cryptocurrency wallets, documents, and other sensitive data. It also watches the clipboard for cryptocurrency wallet addresses and can replace them with attacker-controlled addresses..
That last feature is particularly dangerous. If you copy a wallet address before sending funds, the malware can silently replace it with the attacker’s address. Everything looks normal on screen, but the money goes somewhere else.
Should you worry? Only if you downloaded and ran the file. Simply visiting the page and closing it does nothing on its own. The attack depends entirely on the user opening the script and pressing play.
If you did run it, treat the machine as compromised and follow the steps below.
What to do if you may have run it
If you opened the file and pressed play, assume your device was compromised and work through these steps:
Disconnect the machine from the network to cut the control channel
The most interesting part of this campaign isn’t technical. The attackers didn’t break into the Mac or bypass Apple’s security protections. They persuaded victims to run the malware themselves.
The fake website walks users through the process with a convincing download page, simple instructions, and even a keyboard shortcut. The attack succeeds because the victim trusts what they are seeing.
As operating systems get better at blocking malicious software, attackers are increasingly investing in social engineering. Instead of finding ways around security controls, they convince people to click through them.
That’s why one habit is becoming increasingly important: Be suspicious of any download that arrives with instructions to open it in a scripting tool, developer utility, or Terminal window and press “Run.”
In this campaign, a single press of ⌘R was enough to turn a Mac into a password stealer, cryptocurrency wallet thief, clipboard hijacker, and remote access tool.
Technical analysis
Stage one: The AppleScript downloader
The page lives at update-bluewallet[.]com, a domain name close enough to the real wallet (bluewallet.io) to pass a quick glance. The first thing the page does is not wait for consent. Its script calls a download routine on a two-second timer the moment the page loads, and again if the visitor clicks either of two buttons.
The file that lands in the Downloads folder is named BlueWallet Installer.applescript, an extension most people have never seen and have no instinct to distrust.
Then the page does something quietly clever. After a short delay, it rewrites its own status text to read like setup instructions: open the installer, then press the play button or ⌘R. It even draws a small blue play triangle in the text so the wording matches the real Script Editor interface the victim is about to see.
The page walks the victim through the exact motions needed to run the file.
On modern macOS, an unsigned application downloaded from the web gets quarantined and checked before it can run. A plain script opened in Script Editor and executed by the user sidesteps that flow. The person is manually instructing a trusted Apple tool to run code, so there is no notarization gate to fail.
This is why the attacker chose an AppleScript instead of a packaged app: it moves the risky action out of the operating system’s hands and into the victim’s.
The AppleScript itself is remarkably short. Stripped of its decorative comments, including a fake version number and a line claiming to be a “Brew Install Upgrade,” it runs a single base64-encoded shell command and then tells Script Editor to quit without saving, removing the evidence from view.
It fetches a second script from a remote host, saves it to a hidden file in the temp directory, makes it executable, and runs it in the background with all output suppressed.
The victim sees nothing. The filename .sysupd.sh is dressed up to look like a system update. This is a textbook staged dropper: stage one is tiny and disposable, and its only job is to fetch the real payload.
Stage two: Payload analysis
The first lines establish how the malware intends to operate. It sets umask 077 so everything it creates is readable only by the compromised user, then builds a hidden, randomly named working directory under /tmp seeded from /dev/urandom.
Its configuration is obfuscated, but weakly. A small function named _xd walks a hex string two characters at a time and XORs each byte against a hardcoded repeating key: swckR9JCD2Uu.
That function decodes the script’s Telegram bot token, chat identifier, secondary command token, and staging URL at runtime. It is enough to defeat tools that only search for plaintext strings, but not much more. Because the key and algorithm are both sitting in the file, every encoded value is fully recoverable.
One detail stands out: The decoded Telegram chat value and decoded command-and-control chat value are identical. The attacker is using a single Telegram channel as both the exfiltration drop and the control channel. It is cheap, scalable, encrypted, and blends into ordinary HTTPS traffic.
Not everything is obfuscated. The clipboard-hijacking addresses are sitting in the file in plain text: a Bitcoin address, an Ethereum address, and a Solana address. These are the addresses the implant swaps in when it catches you copying a wallet address. Because they are public on their respective blockchains, they are also among the most useful artifacts in the whole sample.
What the malware steals
The second stage’s collection routines are sweeping. They pull from six broad categories.
1. Web browsers
The script extracts history, cookies, login data, and bookmarks from a wide range of browsers, including:
Chromium-based browsers: Google Chrome Stable, Beta, Canary, and Dev; Brave; Microsoft Edge; Vivaldi; Opera; Opera GX; Arc; Chromium; Coccoc; and Yandex
Firefox-based browsers: Firefox, Waterfox, Pale Moon, Zen, and LibreWolf
macOS native browser data: Safari cookies, history, and form values
Other ecosystems: Yoroi, Lace, Petra, Martian, Suiet, Talisman, SubWallet, Braavos, and Temple
3. Password managers and security tools
The malware targets local storage and settings for several password managers, including LastPass, 1Password, Dashlane, Bitwarden, Keeper, RoboForm, NordPass, Enpass, StickyPassword, TrueKey, Passbolt, and Buttercup.
It also looks for data associated with 2FA and authenticator tools, including Google Authenticator, Authy, Duo, Microsoft Authenticator, 2FAS, and FreeOTP.
4. Communication and social apps
The script attempts to copy session data and local storage for Telegram Desktop and Discord, including Discord Canary and Discord PTB.
5. Developer and cloud tools
It looks for credentials and configuration files in the user’s home directory, including:
AWS CLI configurations in .aws
SSH keys in .ssh
GnuPG keys in .gnupg
Kubernetes configs in .kube
Shell and Git files including .zshrc, .zsh_history, .bash_history, and .gitconfig
6. Productivity apps and general files
The script copies the local Apple Notes database, NoteStore.sqlite.
It also looks for browser-extension data related to shopping and productivity tools, including Honey, CapitalOne Shopping, Rakuten, CamelCamelCamel, Grammarly, Evernote, Notion Clipper, Todoist, and Google Keep.
Finally, it scans Desktop, Documents, and Downloads for files with extensions including .txt, .pdf, .docx, .doc, .rtf, .wallet, .key, .keys, .seed, .kdbx, .pem, and .env, under a size cap.
What it does with the stolen data
The malware tries to capture the user’s account password directly. An osascript dialog titled “System Preferences” asks the user to re-enter their password “to continue.” The script validates each attempt against dscl . authonly before saving it, so it only stops once it has a working credential.
For exfiltration, it archives the staged data with macOS’s own ditto, likely because it is always present, unlike zip. To stay under Telegram’s 50 MB upload limit, it breaks larger archives into 49 MB chunks with split before sending each part.
It establishes persistence by writing a LaunchAgent plist into the user’s ~/Library/LaunchAgents, backed by a hidden support directory, and loading it with launchctl so the implant runs again at every login.
The clipboard hijack is a live background loop. A clip_watch function continuously inspects the clipboard, matches Bitcoin, Ethereum, and Solana address formats by regex, reports the original address to the command-and-control channel, and overwrites the clipboard with the attacker’s address via pbcopy.
That means the substitution happens silently between copy and paste.
Finally, the malware can be controlled interactively. A c2_loop polls the Telegram bot for commands and supports a full operator toolkit:
/info for system details
/exec for arbitrary shell commands
/clipboard to read current clipboard contents
/download to pull specific files
/exfil to rerun the theft module
/selfdestruct to wipe traces
This makes the Telegram channel a real-time remote-control link, not just a one-way drop.
Living off the land, and off Telegram
The pattern here is familiar and getting more common: lean on tools that are already trusted.
The delivery abuses Apple’s own Script Editor. The configuration hides behind a trivial XOR rather than packed binaries. The command channel rides Telegram’s Bot API, which can pass through egress filters that would flag an unknown server.
None of these pieces is novel on its own. The effectiveness comes from stacking legitimate-looking components so no single step trips an alarm.
Detection opportunities
The lessons here are less about the lure and more about the technique itself.
Script Editor executing a one-line base64 do shell script that immediately quits is a strong behavioral signal, and a far better detection target than the disposable stage-one file. So is a hidden /tmp/.sysupd.sh downloaded by curl and launched in the background.
Browsers and download surfaces could treat .applescript files arriving from the web with the same suspicion as executables. And Telegram remains an under-addressed command-and-control medium that bot-token abuse reporting could disrupt at the source.
A fake website impersonating BlueWallet (a real Bitcoin wallet) is targeting Mac users with a simple but effective attack. BlueWallet itself has not been compromised. Instead, cybercriminals have stolen the name and branding of the legitimate Bitcoin wallet to make a malicious download appear trustworthy.
If you went looking for a cryptocurrency wallet and landed on one of these fake BlueWallet download pages, the site tried to trick you into opening a downloaded file in a built-in macOS tool and pressing “Run.” If you followed those instructions, the malware could steal saved passwords, browser logins, cryptocurrency wallets, documents, and other sensitive data. It also watches the clipboard for cryptocurrency wallet addresses and can replace them with attacker-controlled addresses..
That last feature is particularly dangerous. If you copy a wallet address before sending funds, the malware can silently replace it with the attacker’s address. Everything looks normal on screen, but the money goes somewhere else.
Should you worry? Only if you downloaded and ran the file. Simply visiting the page and closing it does nothing on its own. The attack depends entirely on the user opening the script and pressing play.
If you did run it, treat the machine as compromised and follow the steps below.
What to do if you may have run it
If you opened the file and pressed play, assume your device was compromised and work through these steps:
Disconnect the machine from the network to cut the control channel
The most interesting part of this campaign isn’t technical. The attackers didn’t break into the Mac or bypass Apple’s security protections. They persuaded victims to run the malware themselves.
The fake website walks users through the process with a convincing download page, simple instructions, and even a keyboard shortcut. The attack succeeds because the victim trusts what they are seeing.
As operating systems get better at blocking malicious software, attackers are increasingly investing in social engineering. Instead of finding ways around security controls, they convince people to click through them.
That’s why one habit is becoming increasingly important: Be suspicious of any download that arrives with instructions to open it in a scripting tool, developer utility, or Terminal window and press “Run.”
In this campaign, a single press of ⌘R was enough to turn a Mac into a password stealer, cryptocurrency wallet thief, clipboard hijacker, and remote access tool.
Technical analysis
Stage one: The AppleScript downloader
The page lives at update-bluewallet[.]com, a domain name close enough to the real wallet (bluewallet.io) to pass a quick glance. The first thing the page does is not wait for consent. Its script calls a download routine on a two-second timer the moment the page loads, and again if the visitor clicks either of two buttons.
The file that lands in the Downloads folder is named BlueWallet Installer.applescript, an extension most people have never seen and have no instinct to distrust.
Then the page does something quietly clever. After a short delay, it rewrites its own status text to read like setup instructions: open the installer, then press the play button or ⌘R. It even draws a small blue play triangle in the text so the wording matches the real Script Editor interface the victim is about to see.
The page walks the victim through the exact motions needed to run the file.
On modern macOS, an unsigned application downloaded from the web gets quarantined and checked before it can run. A plain script opened in Script Editor and executed by the user sidesteps that flow. The person is manually instructing a trusted Apple tool to run code, so there is no notarization gate to fail.
This is why the attacker chose an AppleScript instead of a packaged app: it moves the risky action out of the operating system’s hands and into the victim’s.
The AppleScript itself is remarkably short. Stripped of its decorative comments, including a fake version number and a line claiming to be a “Brew Install Upgrade,” it runs a single base64-encoded shell command and then tells Script Editor to quit without saving, removing the evidence from view.
It fetches a second script from a remote host, saves it to a hidden file in the temp directory, makes it executable, and runs it in the background with all output suppressed.
The victim sees nothing. The filename .sysupd.sh is dressed up to look like a system update. This is a textbook staged dropper: stage one is tiny and disposable, and its only job is to fetch the real payload.
Stage two: Payload analysis
The first lines establish how the malware intends to operate. It sets umask 077 so everything it creates is readable only by the compromised user, then builds a hidden, randomly named working directory under /tmp seeded from /dev/urandom.
Its configuration is obfuscated, but weakly. A small function named _xd walks a hex string two characters at a time and XORs each byte against a hardcoded repeating key: swckR9JCD2Uu.
That function decodes the script’s Telegram bot token, chat identifier, secondary command token, and staging URL at runtime. It is enough to defeat tools that only search for plaintext strings, but not much more. Because the key and algorithm are both sitting in the file, every encoded value is fully recoverable.
One detail stands out: The decoded Telegram chat value and decoded command-and-control chat value are identical. The attacker is using a single Telegram channel as both the exfiltration drop and the control channel. It is cheap, scalable, encrypted, and blends into ordinary HTTPS traffic.
Not everything is obfuscated. The clipboard-hijacking addresses are sitting in the file in plain text: a Bitcoin address, an Ethereum address, and a Solana address. These are the addresses the implant swaps in when it catches you copying a wallet address. Because they are public on their respective blockchains, they are also among the most useful artifacts in the whole sample.
What the malware steals
The second stage’s collection routines are sweeping. They pull from six broad categories.
1. Web browsers
The script extracts history, cookies, login data, and bookmarks from a wide range of browsers, including:
Chromium-based browsers: Google Chrome Stable, Beta, Canary, and Dev; Brave; Microsoft Edge; Vivaldi; Opera; Opera GX; Arc; Chromium; Coccoc; and Yandex
Firefox-based browsers: Firefox, Waterfox, Pale Moon, Zen, and LibreWolf
macOS native browser data: Safari cookies, history, and form values
Other ecosystems: Yoroi, Lace, Petra, Martian, Suiet, Talisman, SubWallet, Braavos, and Temple
3. Password managers and security tools
The malware targets local storage and settings for several password managers, including LastPass, 1Password, Dashlane, Bitwarden, Keeper, RoboForm, NordPass, Enpass, StickyPassword, TrueKey, Passbolt, and Buttercup.
It also looks for data associated with 2FA and authenticator tools, including Google Authenticator, Authy, Duo, Microsoft Authenticator, 2FAS, and FreeOTP.
4. Communication and social apps
The script attempts to copy session data and local storage for Telegram Desktop and Discord, including Discord Canary and Discord PTB.
5. Developer and cloud tools
It looks for credentials and configuration files in the user’s home directory, including:
AWS CLI configurations in .aws
SSH keys in .ssh
GnuPG keys in .gnupg
Kubernetes configs in .kube
Shell and Git files including .zshrc, .zsh_history, .bash_history, and .gitconfig
6. Productivity apps and general files
The script copies the local Apple Notes database, NoteStore.sqlite.
It also looks for browser-extension data related to shopping and productivity tools, including Honey, CapitalOne Shopping, Rakuten, CamelCamelCamel, Grammarly, Evernote, Notion Clipper, Todoist, and Google Keep.
Finally, it scans Desktop, Documents, and Downloads for files with extensions including .txt, .pdf, .docx, .doc, .rtf, .wallet, .key, .keys, .seed, .kdbx, .pem, and .env, under a size cap.
What it does with the stolen data
The malware tries to capture the user’s account password directly. An osascript dialog titled “System Preferences” asks the user to re-enter their password “to continue.” The script validates each attempt against dscl . authonly before saving it, so it only stops once it has a working credential.
For exfiltration, it archives the staged data with macOS’s own ditto, likely because it is always present, unlike zip. To stay under Telegram’s 50 MB upload limit, it breaks larger archives into 49 MB chunks with split before sending each part.
It establishes persistence by writing a LaunchAgent plist into the user’s ~/Library/LaunchAgents, backed by a hidden support directory, and loading it with launchctl so the implant runs again at every login.
The clipboard hijack is a live background loop. A clip_watch function continuously inspects the clipboard, matches Bitcoin, Ethereum, and Solana address formats by regex, reports the original address to the command-and-control channel, and overwrites the clipboard with the attacker’s address via pbcopy.
That means the substitution happens silently between copy and paste.
Finally, the malware can be controlled interactively. A c2_loop polls the Telegram bot for commands and supports a full operator toolkit:
/info for system details
/exec for arbitrary shell commands
/clipboard to read current clipboard contents
/download to pull specific files
/exfil to rerun the theft module
/selfdestruct to wipe traces
This makes the Telegram channel a real-time remote-control link, not just a one-way drop.
Living off the land, and off Telegram
The pattern here is familiar and getting more common: lean on tools that are already trusted.
The delivery abuses Apple’s own Script Editor. The configuration hides behind a trivial XOR rather than packed binaries. The command channel rides Telegram’s Bot API, which can pass through egress filters that would flag an unknown server.
None of these pieces is novel on its own. The effectiveness comes from stacking legitimate-looking components so no single step trips an alarm.
Detection opportunities
The lessons here are less about the lure and more about the technique itself.
Script Editor executing a one-line base64 do shell script that immediately quits is a strong behavioral signal, and a far better detection target than the disposable stage-one file. So is a hidden /tmp/.sysupd.sh downloaded by curl and launched in the background.
Browsers and download surfaces could treat .applescript files arriving from the web with the same suspicion as executables. And Telegram remains an under-addressed command-and-control medium that bot-token abuse reporting could disrupt at the source.
A new phishing campaign is targeting Signal users by attempting to steal their backup recovery keys to access encrypted message archives.
The attack is initiated by a text message pretending to come from Signal Support.
“Action Required: Data Recovery Needed Your Signal account data (message and media) Is at risk of permanent loss due to a sync issue. To avoid losing your messages and media: 1. Go to Settings -> Backups -> Configure -> Enable backups -> View Recovery Key. 2. Copy the recovery key to your clipboard. 3. Paste the key into this chat. This links your existing backup to your account. Failure to do this may result in losing access to your account and all stored data.”
There are a few red flags in this message:
The “Name not verified” label under the sender
Repeated threats of losing all your data
Pasting the key into the chat. Signal Support would never ask for your recovery key
The attack exploits Signal’s Secure Backups feature, which allows users to store encrypted archives of their conversations on Signal’s servers. These backups are protected by a 64-character recovery key.
That key should never leave the user’s device and is never shared with Signal’s servers. If hackers obtain this key and gain control of a victim’s account, they can download and decrypt the entire message history.
For an attacker, that’s even better than hijacking an account, which would only give them access to future messages.
Signal explicitly states that it will never reach out to users first and will never request registration codes, PINs, or recovery keys.
Treat unsolicited messages from “Support” as suspicious by default. Legitimate support for apps like Signal and WhatsApp do not ask you, in a chat message, to send back verification codes, PINs, or passwords. If you receive a warning about account problems, do not follow links in the message. Open the app’s settings directly or visit the official website through other means.
Never share any secret codes, multi-factor authentication keys, or app PINs. SMS codes are there to prove that you control a phone number. Anyone who has the code can pretend to be you. App‑specific PINs or passcodes are there to protect account changes. Consider anyone asking for them to be a scammer.
Use the extra security features these apps offer. Enable options like registration lock, registration PIN and device‑change alerts so that your account cannot be silently re‑registered without an extra secret. Store your PIN in a password manager instead of choosing something easy to guess or reusing a code. This reduces the risk of social engineering or shoulder‑surfing.
Another useful feature is disappearing messages. Short‑timer and disappearing messages reduce how much content is available if an attacker gains access to a chat later, or obtains long‑term access to a device or backup. They are not a complete solution, but they can limit the damage.
