New email scam uses hidden characters to slip past filters
NEWYou can now listen to Fox News articles!
Cybercriminals keep finding new angles to get your attention, and email remains one of their favorite tools. Over the years, you have probably seen everything from fake courier notices to AI-generated scams that feel surprisingly polished. Filters have improved, but attackers have learned to adapt. The latest technique takes aim at something you rarely think about: the subject line itself. Researchers have found a method that hides tiny, invisible characters inside the subject so automated systems fail to flag the message. It sounds subtle, but it is quickly becoming a serious problem.

How the new trick works
Researchers recently uncovered phishing campaigns that embed soft hyphens between every letter of an email subject. These are invisible Unicode characters that normally help with text formatting. They do not show up in your inbox, but they completely throw off keyword-based filters. Attackers use MIME encoded-word formatting to slip these characters into the subject. By encoding it in UTF-8 and Base64, they can weave these hidden characters through the entire phrase.
One analyzed email decoded to “Your Password is About to Expire” with a soft hyphen tucked between every character. To you, it looks normal. To a security filter, it looks scrambled, with no clear keyword to match. The attackers then use the same trick in the body of the email, so both layers slide through detection. The link leads to a fake login page sitting on a compromised domain, designed to harvest your credentials.
If you have ever tried spotting a phishing email, this one still follows the usual script. It builds urgency, claims something is about to expire and points you to a login page. The difference is in how neatly it dodges the filters you trust.
Why this phishing technique is super dangerous
Most phishing filters rely on pattern recognition. They look for suspicious words, common phrases and structure. They also scan for known malicious domains. By splitting every character with invisible symbols, attackers break up these patterns. The text becomes readable for you but unreadable for automated systems. This creates a quiet loophole where old phishing templates suddenly become effective again.
The worrying part is how easy this method is to copy. The tools needed to encode these messages are widely available. Attackers can automate the process and churn out bulk campaigns with little extra effort. Since the characters are invisible in most email clients, even tech-savvy users do not notice anything odd at first glance.
Security researchers point out that this method has appeared in email bodies for years, but using it in the subject line is less common. That makes it harder for existing filters to catch. Subject lines also play a key role in shaping your first impression. If the subject looks familiar and urgent, you are more likely to open the email, which gives the attacker a head start.
How to spot a phishing email before you click
Phishing emails often look legitimate, but the links inside them tell a different story. Scammers hide dangerous URLs behind familiar-looking text, hoping you will click without checking. One safe way to preview a link is by using a private email service that shows the real destination before your browser loads it.
Our top-rated private email provider recommendation includes malicious link protection that reveals full URLs before opening them. This gives you a clear view of where a link leads before anything can harm your device. It also offers strong privacy features like no ads, no tracking, encrypted messages and unlimited disposable aliases.

9 steps you can take to protect yourself from this phishing scam
You do not need to become a security expert to stay safe. A few habits, paired with the right tools, can shut down most phishing attempts before they have a chance to work.
1) Use a password manager
A password manager helps you create strong, unique passwords for every account. Even if a phishing email fools you, the attacker cannot use your password elsewhere because each one is different. Most password managers also warn you when a site looks suspicious.
Next, see if your email has been exposed in past breaches. Our #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.
Check out the best expert-reviewed password managers of 2025 at Cyberguy.com.
2) Enable two-factor authentication
Turning on 2FA adds a second step to your login process. Even if someone steals your password, they still need the verification code on your phone. This stops most phishing attempts from going any further.
3) Install a reliable antivirus software
Strong antivirus software does more than scan for malware. Many can flag unsafe pages, block suspicious redirects and warn you before you enter your details on a fake login page. It is a simple layer of protection that helps a lot when an email slips past filters.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

4) Limit your personal data online
Attackers often tailor phishing messages using information they find about you. Reducing your digital footprint makes it harder for them to craft emails that feel convincing. You can use personal data removal services to clean up exposed details and old database leaks.
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.

5) Check sender details carefully
Do not rely on the display name. Always check the full email address. Attackers often tweak domain names by a single letter or symbol. If something feels off, open the site manually instead of clicking any link inside the email.
6) Never reset passwords through email links
If you get an email claiming your password will expire, do not click the link. Go to the website directly and check your account settings. Phishing emails rely on urgency. Slowing down and confirming the issue yourself removes that pressure.
7) Keep your software and browser updated
Updates often include security fixes that help block malicious scripts and unsafe redirects. Attackers take advantage of older systems because they are easier to trick. Staying updated keeps you ahead of known weaknesses.
8) Turn on advanced spam filtering or “strict” filtering
Many email providers (Gmail, Outlook, Yahoo) allow you to tighten spam filtering settings. This won’t catch every soft-hyphen scam, but it improves your odds and reduces risky emails overall.
9) Use a browser with anti-phishing protection
Chrome, Safari, Firefox, Brave, and Edge all include anti-phishing checks. This adds another safety net if you accidentally click a bad link.

Kurt’s key takeaway
Phishing attacks are changing fast, and tricks like invisible characters show how creative attackers are getting. It’s safe to say filters and scanners are also improving, but they cannot catch everything, especially when the text they see is not the same as what you see. Staying safe comes down to a mix of good habits, the right tools, and a little skepticism whenever an email pushes you to act quickly. If you slow down, double-check the details, and follow the steps that strengthen your accounts, you make it much harder for anyone to fool you.

Birdbuddy’s new smart feeders aim to make spotting birds easier, even for beginners
Birdbuddy is introducing two new smart bird feeders: the flagship Birdbuddy 2 and the more compact, cheaper Birdbuddy 2 Mini aimed at first-time users and smaller outdoor spaces. Both models are designed to be faster and easier to use than previous generations, with upgraded cameras that can shoot in portrait or landscape and wake instantly when a bird lands so you’re less likely to miss the good stuff.
The Birdbuddy 2 costs $199 and features a redesigned circular camera housing that delivers 2K HDR video, slow-motion recording, and a wider 135-degree field of view. The upgraded built-in mic should also better pick up birdsong, which could make identifying species easier using both sound and sight.
The feeder itself offers a larger seed capacity and an integrated perch extender, along with support for both 2.4GHz and 5GHz Wi-Fi for more stable connectivity. The new model also adds dual integrated solar panels to help keep it powered throughout the day, while adding a night sleep mode to conserve power.
The Birdbuddy 2 Mini is designed to deliver the same core AI bird identification and camera experience, but in a smaller, more accessible package. At 6.95 inches tall with a smaller seed capacity, it’s geared toward first-time smart birders and smaller outdoor spaces like balconies, and it supports an optional solar panel.
Birdbuddy 2’s first batch of preorders has already sold out, with shipments expected in February 2026 and wider availability set for mid-2026. Meanwhile, the Birdbuddy 2 Mini will be available to preorder for $129 in mid-2026, with the company planning on shipping the smart bird feeder in late 2026.

Robots learn 1,000 tasks in one day from a single demo
NEWYou can now listen to Fox News articles!
Most robot headlines follow a familiar script: a machine masters one narrow trick in a controlled lab, then comes the bold promise that everything is about to change. I usually tune those stories out. We have heard about robots taking over since science fiction began, yet real-life robots still struggle with basic flexibility. This time felt different.

ELON MUSK TEASES A FUTURE RUN BY ROBOTS

How robots learned 1,000 physical tasks in one day
A new report published in Science Robotics caught our attention because the results feel genuinely meaningful, impressive and a little unsettling in the best way. The research comes from a team of academic scientists working in robotics and artificial intelligence, and it tackles one of the field’s biggest limitations.
The researchers taught a robot to learn 1,000 different physical tasks in a single day using just one demonstration per task. These were not small variations of the same movement. The tasks included placing, folding, inserting, gripping and manipulating everyday objects in the real world. For robotics, that is a big deal.
Why robots have always been slow learners
Until now, teaching robots physical tasks has been painfully inefficient. Even simple actions often require hundreds or thousands of demonstrations. Engineers must collect massive datasets and fine-tune systems behind the scenes. That is why most factory robots repeat one motion endlessly and fail as soon as conditions change. Humans learn differently. If someone shows you how to do something once or twice, you can usually figure it out. That gap between human learning and robot learning has held robotics back for decades. This research aims to close that gap.
THE NEW ROBOT THAT COULD MAKE CHORES A THING OF THE PAST

How the robot learned 1,000 tasks so fast
The breakthrough comes from a smarter way of teaching robots to learn from demonstrations. Instead of memorizing entire movements, the system breaks tasks into simpler phases. One phase focuses on aligning with the object, and the other handles the interaction itself. This method relies on artificial intelligence, specifically an AI technique called imitation learning that allows robots to learn physical tasks from human demonstrations.
The robot then reuses knowledge from previous tasks and applies it to new ones. This retrieval-based approach allows the system to generalize rather than start from scratch each time. Using this method, called Multi-Task Trajectory Transfer, the researchers trained a real robot arm on 1,000 distinct everyday tasks in under 24 hours of human demonstration time.
Importantly, this was not done in a simulation. It happened in the real world, with real objects, real mistakes and real constraints. That detail matters.
Why this research feels different
Many robotics papers look impressive on paper but fall apart outside perfect lab conditions. This one stands out because it tested the system through thousands of real-world rollouts. The robot also showed it could handle new object instances it had never seen before. That ability to generalize is what robots have been missing. It is the difference between a machine that repeats and one that adapts.

A long-standing robotics problem may finally be cracking
This research addresses one of the biggest bottlenecks in robotics: inefficient learning from demonstrations. By decomposing tasks and reusing knowledge, the system achieved an order of magnitude improvement in data efficiency compared to traditional approaches. That kind of leap rarely happens overnight. It suggests that the robot-filled future we have talked about for years may be nearer than it looked even a few years ago.
What this means for you
Faster learning changes everything. If robots need less data and less programming, they become cheaper and more flexible. That opens the door to robots working outside tightly controlled environments.
In the long run, this could enable home robots to learn new tasks from simple demonstrations instead of specialist code. It also has major implications for healthcare, logistics and manufacturing.
More broadly, it signals a shift in artificial intelligence. We are moving away from flashy tricks and toward systems that learn in more human-like ways. Not smarter than people. Just closer to how we actually operate day to day.

Kurt’s key takeaways
Robots learning 1,000 tasks in a day does not mean your house will have a humanoid helper tomorrow. Still, it represents real progress on a problem that has limited robotics for decades. When machines start learning more like humans, the conversation changes. The question shifts from what robots can repeat to what they can adapt to next. That shift is worth paying attention to.

Plaud updates the NotePin with a button
Plaud has updated its compact NotePin AI recorder. The new NotePin S is almost identical to the original, except for one major difference: a button. It’s joined by a new Plaud Desktop app for recording audio in online meetings, which is free to owners of any Plaud Note or NotePin.
The NotePin S has the same FitBit-esque design as the 2024 original and ships with a lanyard, wristband, clip, and magnetic pin, so you can wear it just about any way you please — now all included in the box, whereas before the lanyard and wristband were sold separately.
It’s about the same size as the NotePin, comes in the same colors (black, purple, or silver), offers similar battery life, and still supports Apple Find My. Like the NotePin, it records audio and generates transcriptions and summaries, whether those are meeting notes, action points, or reminders.
But now it has a button. Whereas the first NotePin used haptic controls, relying on a long squeeze to start recording, with a short buzz to let you know it worked, the S switches to something simpler. A long press of the button starts recording, a short tap adds highlight markers. Plaud’s explanation for the change is simple: buttons are less ambiguous, so you’ll always know you’ve successfully pressed it and started recording, whereas original NotePin users complained they sometimes failed to record because they hadn’t squeezed just right.
AI recorders like this live or die by ease of use, so removing a little friction gives Plaud better odds of survival.
Alongside the NotePin S, Plaud is launching a new Mac and PC application for recording the audio from online meetings. Plaud Desktop runs in the background and activates whenever it detects calls from apps including Zoom, Meet, and Teams, recording both system audio and from your microphone. You can set it to either record meetings automatically or require manual activation, and unlike some alternatives it doesn’t create a bot that joins the call with you.
Recordings and notes are synced with those from Plaud’s line of hardware recorders, with the same models used for transcription and generation, creating a “seamless” library of audio from your meetings, both online and off.
Plaud Desktop is available now and is free to anyone who already owns a Plaud Note or NotePin device. The new NotePin S is also available today, for $179 — $20 more than the original, which Plaud says will now be phased out.
