There's a lot of buzz around AI malware lately, and it might sound like something straight out of a sci-fi movie 🤖. But the reality is a bit more subtle and crucial to understand.

Attackers are getting faster, not smarter. With AI tools, they can whip up scripts, tweak their attacks, and create convincing messages in no time. What once required skill and effort can now be done quickly, even by those with less experience.

This shift has major implications. Phishing emails don’t need to be perfect; they just have to be believable and sent in bulk. If they reach enough inboxes and resemble normal business communication, the chances of someone falling for them increase significantly.

On the technical side, attackers can test, adjust, and retry their strategies much more rapidly. Instead of sticking to one method until it gets blocked, they can keep changing it just enough to slip through defences.

That’s why you're hearing more about AI-generated threats. These aren’t fully automated attacks; rather, the people behind them are moving faster and trying more variations with less effort.

For businesses, this means timing is everything ⏳. Once an attacker gains access, the window to detect and respond is much shorter than before. What used to take hours can now happen in a flash, putting pressure on detection and response efforts 🤯.

The fundamentals haven’t changed much; most incidents still start with identity theft. A stolen or guessed password opens the door for attackers to navigate systems unnoticed at first. This is why multi-factor authentication remains crucial; it adds an extra layer that makes stolen passwords significantly less useful.

Visibility is key! Tools like Microsoft Defender help identify unusual behaviour across devices and accounts, ensuring you catch issues before they escalate.

What’s different now? The speed! If attackers can move quickly, defences must keep pace. This means shortening the time between noticing “something seems off” and taking action to contain it.

And remember: not every threat will look obviously malicious. Some may appear as normal emails or logins, just slightly out of place. Awareness and good habits are still vital because many attacks begin with a seemingly harmless moment—a click, a login, or a hasty decision.

💭 If an attack can kick off in just minutes, how quickly would your business notice? What would happen next?

If someone had your phone for 60 seconds, what could they access? 📱

Researchers have demonstrated a vulnerability affecting certain Android devices that could allow sensitive data to be extracted with physical access and the right tools.

We're talking about:
⚠️ Messages and emails
⚠️ Photos and files
⚠️ Saved credentials
⚠️ Business data
⚠️ Cryptocurrency wallets

The good news? This isn't a remote attack, and security patches have already been released.

But it's a timely reminder that cybersecurity isn't just about protecting laptops and servers. Mobile devices often hold just as much sensitive information.

Keeping devices updated, securing access properly, and thinking carefully about what is stored on them remains essential.

Phones get lost. Phones get stolen.

The question is: if yours fell into the wrong hands, would you be comfortable with what it could reveal?

“We’re fine. We use Macs.”

I hear this a lot from business owners.

For years, Macs were seen as safer than Windows PCs. But that’s changing fast.

Cyber criminals are now actively targeting macOS businesses, and one of the biggest growing threats is something called info stealer malware ☠️

These attacks are designed to quietly collect sensitive information like:

⚠️ Saved browser sessions
⚠️ Keychains and passwords
⚠️ Cloud access tokens
⚠️ Developer credentials
⚠️ Even cryptocurrency wallets

Once attackers have that information, they can access accounts, send fake invoices, launch ransomware attacks, or get into cloud systems without you realising 😬

The worrying part is how these attacks are spreading.

Researchers have seen fake Google ads, fake software downloads, and even hijacked WhatsApp accounts being used to trick people into installing malware disguised as legitimate Mac files.

Staying protected isn’t about whether you use Mac or Windows anymore. It’s about how well your systems, cloud platforms, and users are protected 👀

🤔 If your business uses Macs, do you feel confident you’d spot something like this before damage was done?

If you’d like support reviewing your cybersecurity setup, the CHS Networks team is always happy to help.

Microsoft Copilot has quietly added a genuinely useful new feature: Reminders 👍

And interestingly, you don’t need a paid Copilot subscription to use it.

You can now ask Copilot things like:

“Remind me to review my presentation every Monday at 8am.”

Or:

“Remind me in 10 minutes to send that quote.”

Copilot understands natural language, so there’s no fiddling with dates, times, or settings.

It also supports recurring reminders and sends alerts directly to your mobile device through the Copilot app.

A few things to know:

• Free users can create up to 5 reminders
• Microsoft 365 Copilot users can create up to 20
• You’ll need the Copilot mobile app with notifications enabled

This is part of a bigger shift happening with AI tools.

They’re moving beyond simple chatbots and becoming digital assistants that help organise your day, manage tasks, and reduce admin.

That said, we’d still recommend using proper calendar systems for anything business-critical 😊

But as an extra productivity tool?
This is a genuinely useful update.

💬 Would you trust AI to manage your reminders, or are you sticking with traditional calendars?

There’s a subtle change coming to online scams. And it’s not the kind you’re watching out for 👀

When generative AI first arrived, there was a lot of talk about dynamic websites.

Pages that wouldn’t be built once and shown to everyone, but generated on the fly, shaped by your location, device, behaviour, even what you typed to get there.
That future never really showed up.

But it turns out someone’s very interested in it.

Security researchers have been exploring how this idea could be used in phishing attacks, and the results are uncomfortable at best 😬

Let me explain…
You click a link and land on a webpage that looks harmless.
There’s no obvious malware. Nothing suspicious for security tools to grab hold of.
But once the page loads, it asks a legitimate AI service to generate code in real time.
That code is then assembled and run directly in your browser.
The outcome is a fully working phishing page created especially for your visit.�
Different code each time. No fixed “bad page” to analyse. Nothing obvious moving across the network.

Which makes traditional detection much harder.
To reassure you, this is mostly proof-of-concept right now.

The researchers didn’t say they’ve seen this exact technique used live yet. But they were clear that all the pieces already exist.
AI is already being used to write heavily disguised JavaScript.�
AI-assisted malware and ransomware are increasing fast.
�
Dynamic code ex*****on on compromised machines is already common.
Put that together and dynamically generated phishing pages start to feel less like science fiction and more like a preview.

The conclusion is that this is where scams are heading.

Detection will still be possible, but it will rely more on behaviour and context, not just spotting a known “bad” website.

They also flagged tighter controls around which AI tools are allowed at work, and stronger security in AI platforms themselves.

The bigger shift here is psychological.

We’re used to thinking “that page looks fake”. But what happens when the page looks different every time?

🤔 Consider this: If scams stop being static and start being personalised, what will you rely on to decide what’s real and what isn’t?

Excel is crossing an interesting line from “tool that helps you work” to “tool that does some of the work for you” 📊

Late last year, Microsoft introduced Agent Mode in Excel on the web. Now it’s rolling out to Excel on Windows, and it’s more than just a copy-and-paste of the web version.

Let’s rewind a little…
Agent Mode is an AI-powered way of telling Excel what outcome you want, rather than clicking through steps yourself.

Instead of building formulas, charts, or layouts manually, you describe the result and Excel works through the steps on your behalf.
Think of it less as “help me write a formula” and more as “build this whole thing for me”.
What’s changed with the Windows version is how flexible it’s become.

Agent Mode now plugs directly into Copilot inside Excel, and you can choose which AI model does the thinking.
Some models are better at fast, structured tasks.
Others are better at detailed, exploratory work.

Excel can pick automatically, or you can override it if you care about that level of control.

Under the hood, that includes models from OpenAI and Anthropic, but you don’t need to understand the difference to use it. “Auto” mode handles that.

The practical improvements matter more.

Agent Mode is now quicker and more reliable when doing everyday Excel jobs, like creating workbooks, fixing broken formulas, generating charts, and even pulling in live data from the web when needed.

You give it an outcome-based instruction, and it builds toward that result.

You should still sanity-check what it produces (always sanity-check), but it dramatically reduces the setup work.

Spreadsheets aren’t going away. But the skill is shifting from how to build everything to how to ask for the right result.

Knowing what you want matters more than knowing every button.

One important footnote: It’s not rolling out to the UK just yet. When it does, this will be a genuine change in how people will use Excel over the next few years.

Here’s a counter-intuitive AI tip I didn’t expect to be sharing 🤖

Being mean to ChatGPT can sometimes get you better answers...
Before you ask, no, I’m not having a bad day 🤣
Tools like ChatGPT and Microsoft Copilot are what’s called generative AI.
That means they don’t look up answers like Google. They generate replies based on patterns they’ve seen before.

Sometimes that goes brilliantly.
Sometimes they confidently make things up.
That’s why you’ll often see the little warning at the bottom saying it can make mistakes.

Even Sam Altman, the CEO of OpenAI, has said he’s surprised by how much people trust ChatGPT, given that it can “hallucinate” (AI-speak for confidently being wrong).

But get this…

Researchers at Pennsylvania State University ran a study using an older version of ChatGPT. They asked it the same questions in different ways. Polite prompts. Neutral prompts. And rude ones.

The rude ones performed better 😡
Noticeably better.
Short, blunt, even mildly insulting instructions produced more accurate answers than overly polite, flowery requests.

The theory is that direct language reduces ambiguity. The AI focuses on the task, not the tone.
Before you unleash your inner Gordon Ramsey 😅 the researchers were clear this isn’t a free pass to be unpleasant.

Normalising rude language has downsides. And future AI models may simply ignore tone altogether.
The real skill isn’t being nice or nasty. It’s being clear.

If you say: “Can you maybe help me understand this, if that’s okay?”, you’ll often get a vague answer back.

If you say: “Explain this in simple terms. Assume I’m not technical. Give me a practical example.” the quality jumps immediately.

That’s prompt engineering (aka “learning how to ask better questions”).
Both Microsoft and OpenAI have said most AI frustrations come down to poor prompts, not bad technology.

There’s also growing evidence that leaning on AI too heavily can dull critical thinking and confidence over time. So, it shouldn’t replace your judgement; it should just support it.

So no, don’t be cruel to AI.

But do be firm. Clear. Specific. And a little less polite if politeness is getting in the way of precision 🙂

🚨 A new phishing campaign skips email, targeting executives and IT admins via LinkedIn messages.

Victims receive seemingly legitimate job offers or project proposals with download links to disguised malicious files. These files appear normal but use DLL sideloading to load harmful code alongside a trusted application.

The attack creates a startup entry, enabling remote access to the attacker after reboot.

Phishing isn't confined to inboxes anymore; social platforms like LinkedIn are ripe for abuse due to their informal nature and personalised outreach.

Remember, just because you didn’t get an email doesn’t mean you weren’t phished! Be cautious with messages that feel relevant and professional. 👀

👉 What makes you hesitate before clicking on such messages?

Microsoft has taken another big step in the AI arms race 🤖
This time it’s with Maia 200. A brand-new AI chip designed and built by Microsoft itself.

Now, before your eyes glaze over at the word chip 😴 I promise, this matters to everyday businesses…
AI tools don’t just exist in the cloud. They run on real, physical hardware inside data centres.
The faster and more efficient that hardware is, the better AI tools perform. And the cheaper they are to run at scale.

Maia 200 is the next generation of Microsoft’s own AI hardware.
It’s purpose-built for AI workloads, meaning it can run very large AI models using fewer machines, less power, and less wasted effort.
Simply put: More work done, with less kit 💪
This also explains why Microsoft is doing it.

By designing its own AI chips, Microsoft can make Microsoft Azure a faster and more efficient place to run AI than rivals, like Amazon Web Services and Google Cloud.
Whoever controls the hardware gets a big say in performance, pricing, and reliability.
And this isn’t a future promise.

Microsoft is already using Maia 200 to power parts of Microsoft 365 Copilot and its internal AI platforms.
It’s rolling out across US data centres first, with more regions to follow, and developers and researchers are being invited to test it early.

You don’t need to understand the technical specs to spot the pattern 🚀

AI is shifting from a clever feature to foundational infrastructure, like electricity, internet, or cloud computing before it.

The businesses building that infrastructure now are shaping how powerful, affordable, and dependable AI becomes for everyone else.

So, here’s the question I’ll leave you with 👇

When AI becomes as ordinary as email in business, do you want to be playing catch up or ahead of your competitors?
