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.

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.

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.

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.

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.
