Roger Linn is a legend in the world of musical instruments. He’s been at the cutting edge of music technology for decades. He created the LM-1, the first drum machine to use samples, and its successor, the LinnDrum, is one of the most iconic drum machines of all time. They were used on countless records in the 1980s, including hits by Tom Petty, Queen, and Tears for Fears. But the most notable fan was probably Prince, who used them extensively on Purple Rain and 1999.

Android malware hidden in fake antivirus app
NEWYou can now listen to Fox News articles!
If you use an Android phone, this deserves your attention.
Cybersecurity researchers warn that hackers are using Hugging Face, a popular platform for sharing artificial intelligence (AI) tools, to spread dangerous Android malware.
At first, the threat appears harmless because it is disguised as a fake antivirus app. Then, once you install it, criminals gain direct access to your device. Because of this, the threat stands out as especially troubling. It combines two things people already trust — security apps and AI platforms.

What Hugging Face is and why it matters
For anyone unfamiliar, Hugging Face is an open platform where developers share AI, NLP and machine learning models. It is widely used by researchers and startups and has become a central hub for AI experimentation. That openness is also what attackers exploited. Because Hugging Face allows public repositories and supports many file types, criminals were able to host malicious code in plain sight.
The fake antivirus app behind the attack
The malware first appeared in an Android app called TrustBastion. On the surface, it looks like a helpful security tool. It promises virus protection, phishing defense and malware blocking. In reality, it does the opposite.
Once installed, TrustBastion immediately claims your phone is infected. It then pressures you to install an update. That update delivers the malicious code. This tactic is known as scareware. It relies on panic and urgency to push users into tapping before thinking.
FAKE ERROR POPUPS ARE SPREADING MALWARE FAST

How the malware spreads and adapts
According to Bitdefender, a global cybersecurity company, the campaign centers on a fake Android security app called TrustBastion. Victims were likely shown ads or warnings claiming their device was infected and were instructed to manually install the app.
The attackers hosted TrustBastion’s APK files directly on Hugging Face, placing them inside public datasets that appeared legitimate at first glance. Once installed, the app immediately prompted users to install a required “update,” which delivered the actual malware.
After researchers reported the malicious repository, it was taken down. However, Bitdefender observed that nearly identical repositories quickly reappeared, with small cosmetic changes but the same malicious behavior. That rapid re-creation made the campaign harder to fully shut down.
What this Android malware can actually do
This Trojan is not minor or annoying. It is invasive. Bitdefender says the malware can:
Take screenshots of your device
Show fake login screens for financial services
Capture your lock screen PIN
Once collected, that data is sent to a third-party server. From there, attackers can move quickly to drain accounts or lock you out of your own phone.
What Google says about the threat
Google says users who stick to official app stores are protected. A Google spokesperson told CyberGuy, “Based on our current detection, no apps containing this malware are found on Google Play.
“Android users are automatically protected against known versions of this malware by Google Play Protect, which is on by default on Android devices with Google Play Services.
“Google Play Protect can warn users or block apps known to exhibit malicious behavior, even when those apps come from sources outside of Play.”

How to stay safe from Hugging Face Android malware
This threat is a reminder that small choices matter. Here is what you should do right now:
1) Stick to trusted app stores
Only download apps from reputable sources like Google Play Store or the Samsung Galaxy Store. These platforms have moderation and scanning in place.
2) Read reviews before installing
Look closely at ratings, download counts and recent comments. Fake security apps often have vague reviews or sudden rating spikes.
3) Use a data removal service
Even careful users can have personal data exposed. A data removal service helps remove your phone number, email and other details from data broker sites that criminals rely on. That reduces follow-up scams, fake security alerts and account takeover attempts.
While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice. They aren’t cheap, and neither is your privacy.
These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites. It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet. By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.

4) Run Play Protect and use strong antivirus software
Scan your device regularly with Play Protect and back it up with strong antivirus software for added protection. Google Play Protect, which is built-in malware protection for Android devices, automatically removes known malware. However, it is important to note that Google Play Protect may not be enough. Historically, it hasn’t been 100% effective at removing all known malware from Android devices.
The best way to protect yourself against malicious links that install malware and potentially access your private information is to have strong antivirus software installed on all your devices. This protection can also help you detect phishing emails and ransomware, keeping your personal information and digital assets safe.

5) Avoid sideloading APK files
Avoid installing apps from websites outside the app store. These apps bypass security checks, so always verify the publisher name and URL.
6) Lock down your Google account
Your phone security depends on it. Enable two-step verification (2FA) first, then use a strong, unique password stored in a password manager to prevent account takeovers.
Next, see if your email has been exposed in past breaches. Our No. 1 password manager (see Cyberguy.com) pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

7) Be cautious with permissions
Be cautious with accessibility permissions. Malware often abuses them to take control of your device.
8) Watch app updates closely
Malware can hide inside fake updates. Be cautious of urgent fixes that push you outside the app store.
Kurt’s key takeaways
This attack shows how quickly trust can be weaponized. A platform designed to advance AI research was repurposed as a delivery system for malware. A fake antivirus app became the threat it claimed to stop. Staying safe no longer means avoiding sketchy-looking apps. It means questioning even those apps that appear helpful and professional.

Somehow, those are not his greatest contributions to the music world. That would, undoubtedly, be the MPC. Linn partnered with Akai to create one of the most popular and important samplers ever. The MPC60 and its successors became the tool of choice for countless hip-hop and house producers. J Dilla’s MPC 3000 even sits in the Smithsonian.
Roger Linn was also an early adopter of MPE, or MIDI polyphonic expression. It’s a key feature of his LinnStrument, an expressive 3D controller released in 2014 — three years before the Association of Musical Electronics Industry (AMEI) officially released the MPE standard. Turns out the man stays so innovative by keeping things simple and focused.

NEWYou can now listen to Fox News articles!
A robot mower sounds like the kind of yard tool that should make life easier. It cuts the grass, saves you time and quietly handles a chore most people would rather avoid.
But a new independent security report raises a bigger concern about what may be happening behind the scenes. Security researcher Andreas Makris says Yarbo robots, which include autonomous lawn mowers and snow blowers, contained serious flaws that could expose owners to remote access, live camera viewing and Wi-Fi credential theft. The report says roughly 6,000 robots are currently affected.
Yarbo has since responded through its Security Center, saying the core technical findings are accurate and that it has started rolling out security fixes. Still, the report raises important questions about how much access smart yard devices should have inside your home network.

SMART HOME HACKING FEARS: WHAT’S REAL AND WHAT’S HYPE
A robot mower connected to home Wi-Fi can create security risks if remote access controls are weak or unclear. (Yarbo)
Yarbo robot security risk: What the report claims
Makris says Yarbo robots ship with a persistent remote access setup that uses a tunnel to reach the robot over the internet. According to the report, the robots also include a hardcoded root password shared across the fleet and a remote connection method tied to the robot’s serial number. That is important because “root” access gives someone deep control over the device. In simple terms, it can mean administrator-level access to the system inside the robot. The report also says the remote tunnel runs automatically, can restart itself if stopped and may return if removed. That raises a major concern for owners because they may not have a simple switch in the app to shut it off.
Why a robot mower could put your home network at risk
Smart devices often need internet access to work. App controls, software updates, diagnostics and support all depend on that connection. However, Makris claims Yarbo’s setup creates a much riskier situation. He says remote access appears to be built into every robot, rather than turned on only when an owner asks for help. The report says an attacker with the right information could potentially reach a robot remotely, access internal functions and use it as a foothold on the owner’s network. So while a robot mower may seem harmless as it cuts grass, rolls through the yard or parks near the garage, that same machine can also connect to your Wi-Fi, carry cameras and sit close to your home every day.
5 WORRISOME PRIVACY CLAUSES HIDDEN IN SMART HOME DEVICES
The Yarbo report raises concerns about remote access, live camera feeds and saved Wi-Fi credentials on connected yard robots. (Yarbo)
Yarbo camera access concerns for homeowners
According to the report, Yarbo robots can have multiple camera feeds. Makris says that if someone gained root access through the remote tunnel, they could potentially view the robot’s surroundings remotely. That could include a driveway, backyard, entryway, garage area or outdoor space where your family spends time. For homeowners, this concern goes beyond a glitch. A camera-equipped device outside your home deserves the same scrutiny as a camera inside your home.
How saved Wi-Fi passwords could be exposed
The report also says an attacker with root access could retrieve saved Wi-Fi credentials from the robot’s system. That would be a serious issue because many homes use one main Wi-Fi network for phones, laptops, tablets, smart TVs, security devices and more. Once someone has your Wi-Fi password, the risk can spread. They may try to reach other connected devices or look for weak spots that were never meant to face the internet. This is why connected outdoor equipment should never get a free pass. A lawn robot may be housed outside or in the garage, but its network access can reach inside.
What Yarbo says now
After Makris published his report, Yarbo posted a response to its Security Center page on its website. The company said the report identified serious vulnerabilities in its remote diagnostic, credential management and data-handling systems. Yarbo co-founder Kenneth Kohlmann also said the “core technical findings are accurate” and acknowledged that the company’s initial response did not reflect the seriousness of the issues.
Yarbo says the problems primarily involved historical design choices in parts of its remote diagnostic, access management and data-handling systems. The company also said some legacy support tools did not give users enough visibility or control. Yarbo said some authentication and credential systems did not meet its current security expectations.
A NEW SECURITY SEAL OF APPROVAL IS COMING TO YOUR SMART HOME GADGETS
Security experts recommend keeping smart yard devices on a guest network instead of your main home Wi-Fi. (Yarbo)
What Yarbo says it has fixed
Yarbo says it has taken several remediation steps since the report was published. According to the company, it has retired historical fleet-level root credentials, revoked shared FRP remote-access credentials and disabled related FRP server-side connection paths.
The company also says updated versions of the Yarbo mobile app no longer contain static credentials or embedded access mechanisms capable of directly authenticating against backend services. Yarbo says it has removed reporting scripts, legacy dependencies and non-essential network configurations that no longer served a necessary product function.
However, Yarbo says more work remains. The company says it is rebuilding its credential management system so any remaining shared-credential models can be replaced with individually scoped, per-device credentials. Each credential would support independent rotation and revocation.
Why Yarbo data connections raise privacy questions
The report also points to connections involving Hanyangtech, Yarbo’s Shenzhen-based parent company, along with ByteDance Feishu, Tencent TDMQ and Chinese DNS resolvers. Makris says some robot telemetry can be sent to ByteDance’s Feishu platform and that certain infrastructure choices are built into the firmware.
Yarbo now says it has removed reporting scripts, legacy dependencies and non-essential network configurations that no longer served a necessary operational or product function. The company also says historical servers and legacy access channels will continue to be phased out as part of its remediation work.
The core issue is transparency. Owners should know where their devices send data, which companies can access it and whether those connections are essential for normal use. That level of clarity matters even more for devices with cameras, location data and access to home networks.
What this means for you
If you own a Yarbo robot, this report means you should treat it like any other connected device with cameras, location data and access to your home Wi-Fi. Yarbo says it is pushing security updates automatically to connected devices. That means owners should connect their Yarbo long enough to receive the latest security update. After that, consider moving it back to a guest network or an isolated smart-device network.
CyberGuy reached out to Yarbo, and a representative said the company encouraged readers to refer to the Security Center at yarbo.com/pages/yarbo-security-center for the latest verified information and ongoing updates.
How Yarbo owners can reduce the risk
You may not be able to control everything happening inside the robot, but you can take a few practical steps to limit what it can reach on your home network.
1) Put the robot on a guest network
Do not keep your robot mower on the same network as your laptop, phone or security cameras. Use a guest network or a separate smart-device network if your router supports it.
2) Change your main Wi-Fi password if you are concerned
If your robot has connected to your main Wi-Fi and you are worried about exposure, change the Wi-Fi password. Use a strong, unique password and store it in a trusted password manager so you do not have to reuse or remember it. Then reconnect only trusted devices. Check out the best expert-reviewed password managers of 2026 at Cyberguy.com
3) Check your router for unknown devices
Open your router app or admin page and review connected devices. Look for anything unfamiliar. Remove devices you do not recognize.
4) Limit what the robot can access
Some routers let you isolate guest devices. Turn that on when available. This can keep the robot from seeing other devices on your network.
5) Ask Yarbo for specific answers
Owners should ask what remote diagnostic access remains, whether credentials are now unique per robot and whether the company will provide a true off switch for remote diagnostics.
6) Keep the robot updated, but stay cautious
Yarbo says security updates are delivered automatically once devices connect to the internet. Connect the robot through a guest network or an isolated smart-device network so it can receive the latest update without giving it access to your main devices.

Kurt’s key takeaways
The Yarbo report is a reminder that convenience can come with hidden access. A robot mower may seem like a helpful yard tool, but under the hood, it can act like a connected computer with cameras, location data and a path into your network. The biggest concern is control. Owners need to know who can reach their devices, when remote access turns on and whether they can shut it off. A company should not expect you to trust a black box sitting on your Wi-Fi. If you own one of these robots, isolate it from your main network and push Yarbo for clear answers. If you are shopping for any smart yard device, ask about security before you ask about battery life.

Google’s AI Overviews are running into an interesting problem right now. Earlier on Friday, if you searched for the term “disregard,” the AI Overview section would include a response like what you’d see from a more traditional AI chatbot instead of the typical AI summary, as spotted on X. As you can see in the image at the top of this story, I got an AI Overview response that said, “Got it. If you need anything else or have a new question later, just let me know!”
As of Friday afternoon, however, Google isn’t showing an AI Overview for the term “disregard” at all — instead, it shows a list of news stories about the issue first. Google hasn’t replied to our requests for comment. In a statement to Android Authority, a spokesperson said that “We’re aware that AI Overviews are misinterpreting some action-related queries, and we’re working on a fix, which will roll out soon.”
AI Overviews haven’t just been tripping up over the word “disregard.” When searching for “ignore,” Google’s AI Overview section showed the following message to a Verge colleague:
Message received! I’m here and ready to help. What would you like to focus on today? Just let me know if there’s a specific topic, task, or question you’d like to explore.
When they searched “skip,” the AI Overview section said:
It looks like your message was just a test or a typo! Feel free to ask a question, share a prompt, or let me know how I can help you with your tasks today. I’m ready whenever you are!
As of Friday afternoon, Google is still showing me AI Overviews with broken responses when I search for “ignore” and “skip.”
As funny as this all is, it’s almost certainly just some kind of bug — I expect Google will fix it soon enough. Maybe Google Search itself is tired after everything that happened at Google I/O.
Updates, May 22nd: Google now isn’t showing AI Overviews for “disregard.” Also added a Google statement.
