How Manifest v3 forced us to rethink Browser Guard, and why that’s a good thing 

As a Browser Guard user, you might not have noticed much difference lately. Browser Guard still blocks scams and phishing attempts just like always, and, in many cases, even better.

But behind the scenes, almost everything changed. The rules that govern how browser extensions work went through a major overhaul, and we had to completely rebuild how Browser Guard protects you.

First, what is Manifest v3 (and v2)? 

Browser extensions include a configuration file called a “manifest”. Think of it as an instruction manual that tells your browser what an extension can do and how it’s allowed to do it.

Manifest v3 is the latest version of that system, and it’s now the only option allowed in major browsers like Chrome and Edge.

In Manifest v2, Browser Guard could use highly customized logic to analyze and block suspicious activity as it happened, protecting you as you browsed the web.

With Manifest v3, that flexibility is mostly gone. Extensions can no longer run deeply complex, custom logic in the same way. Instead, we can only pass static rule lists to the browser, called Declarative Net Request (DNR) rules.

But those DNR rules come with strict constraints.

Rule sets are size-limited by the browser to save space. Because rules are stored as raw JSON files, developers can’t use other data types to make them smaller. And updating those DNR rules can only be done by updating the extension entirely.

This is less of a problem on Chrome, which allows developers to push updates quickly, but other browsers don’t currently support this fast-track process. Dynamic rule updates exist, but they’re limited, and nowhere near large enough to hold the full set of rules.

In short, we couldn’t simply port Browser Guard from Manifest v2 to v3. The old approach wouldn’t keep our users protected.

A note about Firefox and Brave 

Firefox and Brave chose a different path and continue to support the more flexible Manifest v2 method of blocking requests.

However, since Brave doesn’t have its own extension store, users can only install extensions they already had before Google removed Manifest v2 extensions from the Chrome Web Store. Though Brave also has strong out-of-the-box ad protection.

For Browser Guard users on Firefox, rest assured the same great blocking techniques will continue to work.

How Browser Guard still protects you 

Given all of this, we had to get creative.

Many ad blockers already support pattern-based matching to stop ads and trackers. We asked a different question: what if we could use similar techniques to catch scam and phishing attempts before we know the specific URL is malicious?

Better yet, what if we did it without relying on the new DNR APIs?

So, we built a new pattern-matching system focused specifically on scam and phishing behavior, supporting:

  • Full regex-based URL matching
  • Full XPath and querySelector support
  • Matching against any content on the page
  • Favicon spoof detection

For example, if a site is hosted on Amazon S3, contains a password-input field, and uses a homoglyph in the URL to trick users into thinking they were logging into Facebook, Browser Guard can detect that combination—even if we’ve never seen the URL before.

Fake Facebook login screen

Why this matters more now 

With AI, attackers can create near-perfect duplicates of websites easier than ever. And did you spot the homoglyph in the URL? Nope, neither did I!  

That’s why we designed this system so we can update its rules every 30 minutes, instead of waiting for full extension updates.  

But I still see static blocking rules in Browser Guard 

That’s true—for now.  

We’ve found a temporary workaround that lets us support all the rules that we had before. However, we had to remove some of the more advanced logic that used to sit on top of them.

For example, we can’t use these large datasets to block subframe requests, only main frame requests. Nor can we stack multiple logic layers together; blocking is limited to simple matches (regex, domains and URLs).

Those limits are a big reason we’re investing more heavily in pattern-based and heuristic protection. 

Pure heuristics 

From day one, Browser Guard has used heuristics (behavior) to detect scams and phishing, monitoring behavior on the page to match suspicious activity.

For example, some scam pages deliberately break your browser’s back button by abusing window.replaceState, then trick you into calling that scammer’s “computer helpline.” Others try to convince you to run malicious commands on your computer.

Browser Guard can detect these behaviors and warn you before you fall for them. 

What’s next? 

Did someone say AI?  

You’ve probably seen Scam Guard in other Malwarebytes products. We’re currently working on a version tailored specifically for Browser Guard. More soon!

Final thoughts 

While Manifest v3 introduced meaningful improvements to browser security, it also created real challenges for security tools like Browser Guard.

Rather than scaling back, the Browser Guard team rebuilt our approach from the ground up, focusing on behavior, patterns, and faster response times. The result is protection that’s different under the hood, but just as committed to keeping you safe online.

How fake party invitations are being used to install remote access tools

“You’re invited!” 

It sounds friendly, familiar and quite harmless. But in a scam we recently spotted, that simple phrase is being used to trick victims into installing a full remote access tool on their Windows computers—giving attackers complete control of the system. 

What appears to be a casual party or event invitation leads to the silent installation of ScreenConnect, a legitimate remote support tool quietly installed in the background and abused by attackers. 

Here’s how the scam works, why it’s effective, and how to protect yourself. 

The email: A party invitation 

Victims receive an email framed as a personal invitation—often written to look like it came from a friend or acquaintance. The message is deliberately informal and social, lowering suspicion and encouraging quick action. 

In the screenshot below, the email arrived from a friend whose email account had been hacked, but it could just as easily come from a sender you don’t know.

So far, we’ve only seen this campaign targeting people in the UK, but there’s nothing stopping it from expanding elsewhere. 

Clicking the link in the email leads to a polished invitation page hosted on an attacker-controlled domain. 

Party invitation email from a contact

The invite: The landing page that leads to an installer 

The landing page leans heavily into the party theme, but instead of showing event details, the page nudges the user toward opening a file. None of them look dangerous on their own, but together they keep the user focused on the “invitation” file: 

  • A bold “You’re Invited!” headline 
  • The suggestion that a friend had sent the invitation 
  • A message saying the invitation is best viewed on a Windows laptop or desktop
  • A countdown suggesting your invitation is already “downloading” 
  • A message implying urgency and social proof (“I opened mine and it was so easy!”

Within seconds, the browser is redirected to download RSVPPartyInvitationCard.msi 

The page even triggers the download automatically to keep the victim moving forward without stopping to think. 

This MSI file isn’t an invitation. It’s an installer. 

The landing page

The guest: What the MSI actually does 

When the user opens the MSI file, it launches msiexec.exe and silently installs ScreenConnect Client, a legitimate remote access tool often used by IT support teams.  

There’s no invitation, RSVP form, or calendar entry. 

What happens instead: 

  • ScreenConnect binaries are installed under C:Program Files (x86)ScreenConnect Client 
  • A persistent Windows service is created (for example, ScreenConnect Client 18d1648b87bb3023) 
  • ScreenConnect installs multiple .NET-based components 
  • There is no clear user-facing indication that a remote access tool is being installed 

From the victim’s perspective, very little seems to happen. But at this point, the attacker can now remotely access their computer. 

The after-party: Remote access is established 

Once installed, the ScreenConnect client initiates encrypted outbound connections to ScreenConnect’s relay servers, including a uniquely assigned instance domain.

That connection gives the attacker the same level of access as a remote IT technician, including the ability to: 

  • See the victim’s screen in real time
  • Control the mouse and keyboard 
  • Upload or download files 
  • Keep access even after the computer is restarted 

Because ScreenConnect is legitimate software commonly used for remote support, its presence isn’t always obvious. On a personal computer, the first signs are often behavioral, such as unexplained cursor movement, windows opening on their own, or a ScreenConnect process the user doesn’t remember installing. 

Why this scam works 

This campaign is effective because it targets normal, predictable human behavior. From a behavioral security standpoint, it exploits our natural curiosity and appears to be a low risk. 

Most people don’t think of invitations as dangerous. Opening one feels passive, like glancing at a flyer or checking a message, not installing software. 

Even security-aware users are trained to watch out for warnings and pressure. A friendly “you’re invited” message doesn’t trigger those alarms. 

By the time something feels off, the software is already installed. 

Signs your computer may be affected 

Watch for: 

  • A download or executed file named RSVPPartyInvitationCard.msi 
  • An unexpected installation of ScreenConnect Client 
  • A Windows service named ScreenConnect Client with random characters  
  • Your computer makes outbound HTTPS connections to ScreenConnect relay domains 
  • Your system resolves the invitation-hosting domain used in this campaign, xnyr[.]digital 

How to stay safe  

This campaign is a reminder that modern attacks often don’t break in—they’re invited in. Remote access tools give attackers deep control over a system. Acting quickly can limit the damage.  

For individuals 

If you receive an email like this: 

  • Be suspicious of invitations that ask you to download or open software 
  • Never run MSI files from unsolicited emails 
  • Verify invitations through another channel before opening anything 

If you already clicked or ran the file:  

  • Disconnect from the internet immediately 
  • Check for ScreenConnect and uninstall it if present 
  • Run a full security scan 
  • Change important passwords from a clean, unaffected device 

For organisations (especially in the UK) 

  • Alert on unauthorized ScreenConnect installations
  • Restrict MSI execution where feasible 
  • Treat “remote support tools” as high-risk software
  • Educate users: invitations don’t come as installers 

This scam works by installing a legitimate remote access tool without clear user intent. That’s exactly the gap Malwarebytes is designed to catch.

Malwarebytes now detects newly installed remote access tools and alerts you when one appears on your system. You’re then given a choice: confirm that the tool is expected and trusted, or remove it if it isn’t.

Match, Hinge, OkCupid, and Panera Bread breached by ransomware group

The ShinyHunters ransomware group has claimed the theft of data containing 10 million records belonging to the Match Group and 14 million records from bakery-café chain Panera Bread.

Claims posted by ShinyHunters
Claims posted by ShinyHunters

The Match Group, that runs multiple popular online dating services like Tinder, Match.com, Meetic, OkCupid, and Hinge has confirmed a cyber incident and is investigating the data breach.

Panera Bread also confirmed that an incident occurred and has alerted authorities. “The data involved is contact information,” it said in an emailed statement to Reuters.

ShinyHunters seems to be gaining access through Single-Sign-On (SSO) platforms and using voice-cloning techniques, which has resulted in a growing number of breaches across different companies. However, not all of these breaches have the same impact.

The impact

For the Match Group, ShinyHunters claims:

“Over 10 million records of Hinge, Match, and OkCupid usage data from Appsflyer and hundreds of internal documents.”

Match says there is no evidence that logins, financial data, or private chats were stolen, but Personally Identifiable Information (PII) and tracking data for some users are in scope. A notification process has been set in motion.

For Panera Bread, ShinyHunters claims to have compromised 14 million records containing PII.

Panera Bread reassures users that there is no indication that the hackers accessed user login credentials, financial information, or private communications.

ShinyHunters also breached Bumblr, Carmax, and Edmunds among others, but I wanted to use Panera Bread and the Match Group as two examples that have very different consequences for users.

When your activity on a dating app is compromised, the impact can be deeply personal. Concerns can range from partners, family members, or employers discovering dating profiles to the risk of doxxing. For many people, stigma around certain apps can lead to fears of being outed, accused of infidelity, or even extorted.

The impact of the Panera Bread breach will be very different. “I just ordered a sandwich and now some criminals have my home address?” Data like this is useful to enrich existing data sets. And the more they know, the easier and better they can target you in phishing attempts.

Protecting yourself after a data breach

If you think you have been affected by a data breach, here are steps you can take to protect yourself:

  • Check the company’s advice. Every breach is different, so check with the company to find out what’s happened and follow any specific advice it offers.
  • Change your password. You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
  • Enable two-factor authentication (2FA). If you can, use a FIDO2-compliant hardware key, laptop, or phone as your second factor. Some forms of 2FA can be phished just as easily as a password, but 2FA that relies on a FIDO2 device can’t be phished.
  • Watch out for impersonators. The thieves may contact you posing as the breached platform. Check the official website to see if it’s contacting victims and verify the identity of anyone who contacts you using a different communication channel.
  • Take your time. Phishing attacks often impersonate people or brands you know, and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
  • Consider not storing your card details. It’s definitely more convenient to let sites remember your card details, but it increases risk if a retailer suffers a breach.
  • Set up identity monitoring, which alerts you if your personal information is found being traded illegally online and helps you recover after.

You can use Malwarebytes’ free Digital Footprint scan to find out if your private information is exposed online.

TikTok’s privacy update mentions immigration status. Here’s why.

In 2026, could any five words be more chilling than “We’re changing our privacy terms?”

The timing could not have been worse for TikTok US when it sent millions of US users a mandatory privacy pop-up on January 22. The message forced users to accept updated terms if they wanted to keep using the app. Buried in that update was language about collecting “citizenship or immigration status.”

Specifically, TikTok said:

“Information You Provide may include sensitive personal information, as defined under applicable state privacy laws, such as information from users under the relevant age threshold, information you disclose in survey responses or in your user content about your racial or ethnic origin, national origin, religious beliefs, mental or physical health diagnosis, sexual life or sexual orientation, status as transgender or nonbinary, citizenship or immigration status, or financial information.”

The internet reacted badly. TikTok users took to social media, with some suggesting that TikTok was building a database of immigration status, and others pledging to delete their accounts. It didn’t help that TikTok’s US operation became a US-owned company on the same day, with Senator Ed Markey (D-Mass.) criticizing what he sees as a lack of transparency around the deal.

In this case, things are may be less sinister than you’d think. The language is not new—it first appeared around August 2024. And TikTok is not asking users to provide their immigration status directly.

Instead, the disclosure covers sensitive information that users might voluntarily share in videos, surveys, or interactions with AI features.

The change appears to be driven largely by California’s AB-947, signed in October 2023. The law added immigration status to the state’s definition of sensitive personal information, placing it under stricter protections. Companies are required to disclose how they process sensitive personal information, even if they do not actively seek it out.

Other social media companies, including Meta, do not explicitly mention immigration status in their privacy policies. According to TechCrunch, that difference likely reflects how specific their disclosure language is—not a meaningful difference in what data is actually collected.

One meaningful change in TikTok’s updated policy does concern location tracking. Previous versions stated that TikTok did not collect GPS data from US users. The new policy says it may collect precise location data, depending on user settings. Users can reportedly opt out of this tracking.

Read the whole board, not just one square

So, does this mean TikTok—or any social media company—deserves our trust? That’s a harder question.

There are still red flags. In April, TikTok quietly removed a commitment to notify users before sharing data with law enforcement. According to Forbes, the company has also declined to say whether it shares, or would share, user data with agencies such as the Department of Homeland Security (DHS) or Immigration and Customs Enforcement (ICE).

That uncertainty is the real issue. Social media companies are notorious for collecting vast amounts of user data, and for being vague about how it may be used later. Outrage over a particularly explicit disclosure is understandable, but the privacy problem runs much deeper than a single policy update from one company.

People have reason to worry unless platforms explicitly commit to not collecting or inferring sensitive data—and explicitly commit to not sharing it with government agencies. And even then, skepticism is healthy. These companies have a long history of changing policies quietly when it suits them.

Meta confirms it’s working on premium subscription for its apps

Meta plans to test exclusive features that will be incorporated in paid versions of Facebook, Instagram, and WhatsApp. It confirmed these plans to TechCrunch.

But these plans are not to be confused with the ad-free subscription options that Meta introduced for Facebook and Instagram in the EU, the European Economic Area, and Switzerland in late 2023 and framed as a way to comply with General Data Protection Regulation (GDPR) and Digital Markets Act requirements.

From November 2023, users in those regions could either keep using the services for free with personalized ads or pay a monthly fee for an ad‑free experience. European rules require Meta to get users’ consent in order to show them targeted ads, so this was an obvious attempt to recoup advertising revenue when users declined to give that consent.

This year, users in the UK were given the same choice: use Meta’s products for free or subscribe to use them without ads. But only grudgingly, judging by the tone in the offer… “As part of laws in your region, you have a choice.”

As part of laws in your region, you have a choice
The ad-free option that has been rolling out coincides with the announcement of Meta’s premium subscriptions.

That ad-free option, however, is not what Meta is talking about now.

The newly announced plans are not about ads, and they are also separate from Meta Verified, which starts at around $15 a month and focuses on creators and businesses, offering a verification badge, better support, and anti‑impersonation protection.

Instead, these new subscriptions are likely to focus on additional features—more control over how users share and connect, and possibly tools such as expanded AI capabilities, unlimited audience lists, seeing who you follow that doesn’t follow you back, or viewing stories without the poster knowing it was you.

These examples are unconfirmed. All we know for sure is that Meta plans to test new paid features to see which ones users are willing to pay for and how much they can charge.

Meta has said these features will focus on productivity, creativity, and expanded AI.

My opinion

Unfortunately, this feels like another refusal to listen.

Most of us aren’t asking for more AI in our feeds. We’re asking for a basic sense of control: control over who sees us, what’s tracked about us, and how our data is used to feed an algorithm designed to keep us scrolling.

Users shouldn’t have to choose between being mined for behavioral data or paying a monthly fee just to be left alone. The message baked into “pay or be profiled” is that privacy is now a luxury good, not a default right. But while regulators keep saying the model is unlawful, the experience on the ground still nudges people toward the path of least resistance: accept the tracking and move on.

Even then, this level of choice is only available to users in Europe.

Why not offer the same option to users in the US? Or will it take stronger US privacy regulation to make that happen?

Microsoft Office zero-day lets malicious documents slip past security checks

Microsoft issued an emergency patch for a high-severity zero-day vulnerability in Office that allows attackers to bypass document security checks and is being exploited in the wild via malicious files.

Microsoft pushed the emergency patch for the zero‑day, tracked as CVE-2026-21509, and classified it as a “Microsoft Office Security Feature Bypass Vulnerability” with a CVSS score of 7.8 out of 10.

The flaw allows attackers to bypass Object Linking and Embedding (OLE) mitigations that are designed to block unsafe COM/OLE controls inside Office documents. This means a malicious attachment could infect a PC despite built-in protections.

In a real-life scenario, an attacker creates a fake Word, Excel, or PowerPoint file containing hidden “mini‑programs” or special objects. They can run code and do other things on the affected computer. Normally, Office has safety checks that would block those mini-programs because they’re risky.

However, the vulnerability allows the attacker to tweak the file’s structure and hidden information in a way that tricks Office into thinking the dangerous mini‑program inside the document is harmless. As a result, Office skips the usual security checks and allows the hidden code to run.

As code to test the bypass is publicly available, increasing the risk of exploitation, users are under urgent advice to apply the patch.

Updating Microsoft 365 and Office
Updating Microsoft 365 and Office

How to protect your system

What you need to do depends on which version of Office you’re using.

The affected products include Microsoft Office 2016, 2019, LTSC 2021, LTSC 2024, and Microsoft 365 Apps (both 32‑bit and 64‑bit).

Office 2021 and later are protected via a server‑side change once Office is restarted. To apply it, close all Office apps and restart them.

Office 2016 and 2019 require a manual update. Run Windows Update with the option to update other Microsoft products turned on.

If you’re running build 16.0.10417.20095 or higher, no action is required. You can check your build number by opening any Office app, going to your account page, and selecting About for whichever application you have open. Make sure the build number at the top reads 16.0.10417.20095 or higher.

What always helps:

  • Don’t open unsolicited attachments without verifying them with a trusted sender.
  • Treat all unexpected documents, especially those asking to “enable content” or “enable editing,” as suspicious.
  • Keep macros disabled by default and only allow signed macros from trusted publishers.
  • Use an up-to-date real-time anti-malware solution.
  • Keep your operating system and software fully up to date.

Clawdbot’s rename to Moltbot sparks impersonation campaign

After the viral AI assistant Clawdbot was forced to rename to Moltbot due to a trademark dispute, opportunists moved quickly. Within days, typosquat domains and a cloned GitHub repository appeared—impersonating the project’s creator and positioning infrastructure for a potential supply-chain attack.

The code is clean. The infrastructure is not. With the GitHub downloads and star rating rapidly rising, we took a deep dive into how fake domains target viral open source projects.

Fake domains spring up to impersonate Moltbot's landing page

The background: Why was Clawdbot renamed?

In early 2026, Peter Steinberger’s Clawdbot became one of the fastest-growing open source projects on GitHub. The self-hosted assistant—described as “Claude with hands”—allowed users to control their computer through WhatsApp, Telegram, Discord, and similar platforms.

Anthropic later objected to the name. Steinberger complied and rebranded the project to Moltbot (“molt” being what lobsters do when they shed their shell).

During the rename, both the GitHub organization and X (formerly Twitter) handle were briefly released before being reclaimed. Attackers monitoring the transition grabbed them within seconds.

“Had to rename our accounts for trademark stuff and messed up the GitHub rename and the X rename got snatched by crypto shills.” — Peter Steinberger

“Had to rename our accounts for trademark stuff and messed up the GitHub rename and the X rename got snatched by crypto shills.” — Peter Steinberger

That brief gap was enough.

Impersonation infrastructure emerged

While investigating a suspicious repository, I uncovered a coordinated set of assets designed to impersonate Moltbot.

Domains

  • moltbot[.]you
  • clawbot[.]ai
  • clawdbot[.]you

Repository

  • github[.]com/gstarwd/clawbot — a cloned repository using a typosquatted variant of the former Clawdbot project name

Website

A polished marketing site featuring:

  • professional design closely matching the real project
  • SEO optimization and structured metadata
  • download buttons, tutorials, and FAQs
  • claims of 61,500+ GitHub stars lifted from the real repository

Evidence of impersonation

False attribution: The site’s schema.org metadata falsely claims authorship by Peter Steinberger, linking directly to his real GitHub and X profiles. This is explicit identity misrepresentation.

The site's metadata

Misdirection to an unauthorized repository: “View on GitHub” links send users to gstarwd/clawbot, not the official moltbot/moltbot repository.

Stolen credibility:The site prominently advertises tens of thousands of stars that belong to the real project. The clone has virtually none (although at the time of writing, that number is steadily rising).

The site advertises 61,500+ GitHub stars

Mixing legitimate and fraudulent links: Some links point to real assets, such as official documentation or legitimate binaries. Others redirect to impersonation infrastructure. This selective legitimacy defeats casual verification and appears deliberate.

Full SEO optimization: Canonical tags, Open Graph metadata, Twitter cards, and analytics are all present—clearly intended to rank the impersonation site ahead of legitimate project resources.

The ironic security warning: The impersonation site even warns users about scams involving fake cryptocurrency tokens—while itself impersonating the project.

The site warms about crypto scams.

Code analysis: Clean by design

I performed a static audit of the gstarwd/clawbot repository:

  • no malicious npm scripts
  • no credential exfiltration
  • no obfuscation or payload staging
  • no cryptomining
  • no suspicious network activity

The code is functionally identical to the legitimate project, which is not reassuring.

The threat model

The absence of malware is the strategy. Nothing here suggests an opportunistic malware campaign. Instead, the setup points to early preparation for a supply-chain attack.

The likely chain of events:

A user searches for “clawbot GitHub” or “moltbot download” and finds moltbot[.]you or gstarwd/clawbot.

The code looks legitimate and passes a security audit.

The user installs the project and configures it, adding API keys and messaging tokens. Trust is established.

At a later point, a routine update is pulled through npm update or git pull. A malicious payload is delivered into an installation the user already trusts.

An attacker can then harvest:

  • Anthropic API keys
  • OpenAI API keys
  • WhatsApp session credentials
  • Telegram bot tokens
  • Discord OAuth tokens
  • Slack credentials
  • Signal identity keys
  • full conversation histories
  • command execution access on the compromised machine

What’s malicious, and what isn’t

Clearly malicious

  • false attribution to a real individual
  • misrepresentation of popularity metrics
  • deliberate redirection to an unauthorized repository

Deceptive but not yet malware

  • typosquat domains
  • SEO manipulation
  • cloned repositories with clean code

Not present (yet)

  • active malware
  • data exfiltration
  • cryptomining

Clean code today lowers suspicion tomorrow.

A familiar pattern

This follows a well-known pattern in open source supply-chain attacks.

A user searches for a popular project and lands on a convincing-looking site or cloned repository. The code appears legitimate and passes a security audit.

They install the project and configure it, adding API keys or messaging tokens so it can work as intended. Trust is established.

Later, a routine update arrives through a standard npm update or git pull. That update introduces a malicious payload into an installation the user already trusts.

From there, an attacker can harvest credentials, conversation data, and potentially execute commands on the compromised system.

No exploit is required. The entire chain relies on trust rather than technical vulnerabilities.

How to stay safe

Impersonation infrastructure like this is designed to look legitimate long before anything malicious appears. By the time a harmful update arrives—if it arrives at all—the software may already be widely installed and trusted.

That’s why basic source verification still matters, especially when popular projects rename or move quickly.

Advice for users

  • Verify GitHub organization ownership
  • Bookmark official repositories directly
  • Treat renamed projects as higher risk during transitions

Advice for maintainers

  • Pre-register likely typosquat domains before public renames
  • Coordinate renames and handle changes carefully
  • Monitor for cloned repositories and impersonation sites

Pro tip: Malwarebytes customers are protected. Malwarebytes is actively blocking all known indicators of compromise (IOCs) associated with this impersonation infrastructure, preventing users from accessing the fraudulent domains and related assets identified in this investigation.

Malicious Chrome extensions can spy on your ChatGPT chats

Researchers discovered 16 malicious browser extensions for Google Chrome and Microsoft Edge that steal ChatGPT session tokens, giving attackers access to accounts, including conversation history and metadata.

The 16 malicious extensions (15 for Chrome and 1 for Edge) claim to improve and optimize ChatGPT, but instead siphon users’ session tokens to attackers. Together, they have been downloaded around 900 times, a relatively small number compared to other malicious extensions.

Despite benign descriptions and, in some cases, a “featured” badge, the real goal of these extensions is to hijack ChatGPT identities by stealing session authentication tokens and sending them to attacker-controlled backends.

Possession of these tokens gives attackers the same level of access as the user, including conversation history and metadata.

In addition to your ChatGPT session token, the extensions also send extra details about themselves (such as their version and language settings), along with information about how they’re used, and special keys they get from their own online service.

Taken together, this allows the attackers to build a picture of who you are and how you work online. They can use it to keep recognizing you over time, build a profile of your behavior, and maintain access to your ChatGPT-connected services for much longer. This increases the privacy impact and means a single compromised extension can cause broader harm if its servers are abused or breached.

According to the researchers, this campaign coincides with a broader trend:

“The rapid growth in adoption of AI-powered browser extensions, aimed at helping users with their everyday productivity needs. While most of them are completely benign, many of these extensions mimic known brands to gain users’ trust, particularly those designed to enhance interaction with large language models.”

How to stay safe

Although we always advise people to install extensions only from official web stores, this case proves once again that not all extensions available there are safe. That said, installing extensions from outside official web stores carries an even higher risk.

Extensions listed in official stores undergo a review process before being approved. This process, which combines automated and manual checks, assesses the extension’s safety, policy compliance, and overall user experience. The goal is to protect users from scams, malware, and other malicious activity. However, this review process is not foolproof.

Microsoft and Google have been notified about the abuse. However, extensions that are already installed may remain active in Chrome and Edge until users manually remove them.
