AI is being used across more areas of business every day.

It helps with writing, research, and speeding up routine work. It’s natural to lean on it more over time.

The problem is that it can feel reliable even in situations where it isn’t designed to be. And that confidence can lead to decisions that look sensible on the surface but carry hidden risks…

When someone leaves your business, their access should leave with them.

But often, accounts are missed.

An old login here, a forgotten app there… suddenly someone who no longer works for you could still get into your systems.

If you’re not completely sure that every account has been removed, it’s time to check…

There’s a security story doing the rounds right now that’s needs your attention… especially if your phone holds anything important 📱

Researchers have demonstrated a way to pull sensitive data from certain Android phones in under a minute.

And it’s not as far-fetched as it might sound.

They focused on devices using chips from MediaTek, which are found in a surprisingly large number of Android phones.

The technique they used doesn’t involve tricking someone into clicking a link or installing anything. Instead, it works at a deeper level of the device.

They connected to the phone via USB while it was powered down and accessed a part of the system that’s supposed to keep sensitive data safe.

This area, often described as a “secure zone”, is where things like encryption keys and PIN protection are handled.

From there, they were able to extract those keys, unlock the phone’s storage outside of Android, and work out the PIN.

Once that’s done, the contents of the device become accessible. Messages, photos, files, and even things like crypto wallet data 😱

Now, rest assured, this isn’t something that can be done remotely. Someone would need physical access to the phone and the right tools.

But that doesn’t make it a niche risk.

Phones get lost, stolen, or left unattended all the time, and that’s where this kind of weakness becomes relevant.

What this really highlights is how much trust we place in our phones without thinking about what’s underneath.

They feel secure because they’re personal and protected by a PIN or fingerprint, but they’re still complex systems made up of hardware and software layers.

If there’s a flaw in one of those layers, it can undermine everything else ☠️

The good news is that this vulnerability has been disclosed responsibly and patches have been issued, so keeping devices up to date really does matter here.

It’s also a reminder to think carefully about what ends up stored on a phone, especially anything sensitive or business-critical.

It’s easy to assume that because a device is in your pocket, it’s also under your control.

Most of the time that’s true. But as this shows, control can shift quickly under the right conditions.

🤔 If your phone fell into the wrong hands for a short time, what would it give access to? And is that a level of exposure you’re comfortable with?

Many businesses are still relying on Windows 10 extended support.

It feels like a reasonable decision. The systems continue to run and there’s no immediate disruption.

The difficulty is that extended support is temporary by design.

At some point, it stops, and that leaves you making decisions under pressure if you haven’t planned ahead…

AI projects often begin with energy and good intentions.

There’s curiosity across the team, a few tools get tested, and early results look promising.

Then progress slows. The pilot never quite becomes part of daily work, and the original excitement fades.

If your AI plans feel like they’re drifting, it may be time to tighten the focus before more time and budget disappear…

Replacing a business PC used to be a routine decision.

Now it’s a noticeable expense, especially when the machine still works but just feels slower than it should.

Sometimes small issues stack up over time until the device feels past its best.

But maybe it doesn’t need replacing at all…

For a long time, phishing worked by sending the same fake message or website to thousands of people and hoping a small number would respond.

That model is starting to shift.

Some newer scams are designed to adapt in real time. And that makes them harder for security systems to recognize and block in the usual way…

Your people are drafting emails, summarizing documents, and solving problems faster thanks to AI. It’s great.

But what’s missing in many businesses is the decision about how it should be used.

Without that, people fill in the gaps themselves. And that’s how data can end up in the wrong places…

How often do you reach the end of the day and wonder where the time went?

Everyone’s been working. Nothing’s gone wrong.

Yet the important stuff didn’t quite move forward.

That usually isn’t about effort or focus.

It’s the small, everyday blockers that steal minutes here and there until they’ve taken the whole day with them…

This is one of those stories that reminds us why “I’ll update it later” can be risky 😬

A critical vulnerability has been discovered in a popular WordPress plugin called Advanced Custom Fields: Extended.

It puts around 50,000 websites at risk of full takeover.

To understand why this matters, a bit of context helps.

WordPress powers a huge portion of the web. Many sites rely on plugins to add extra functionality, and one of the most widely used is Advanced Custom Fields (ACF).

It lets developers add custom content fields to pages and posts.

The Extended version builds on that, adding even more flexibility.

The problem is that certain versions of this plugin didn’t properly enforce role restrictions when creating or updating users through forms.

Under the right conditions, someone who isn’t logged in at all could create a new user account and assign themselves the administrator role.

And administrator access on a WordPress site means everything. Content, users, plugins, themes… full control.

Now, there is an important caveat.

This isn’t an exploit that affects every site automatically.

For the vulnerability to be abused, a site needs to be using specific user creation or update forms with role mapping enabled.

That reduces the immediate blast radius.

But the severity rating is still 9.8 out of 10, which tells you how bad things could get if the conditions are right.

The good news is that the issue is fixed in a newer version of the plugin. More than half of affected sites have been updated.

The less good news is that tens of thousands haven’t. And once a vulnerability becomes public, attackers don’t need it to be easy. They need it to be possible.

There’s currently no evidence of this flaw being exploited in the wild. But history tells us that public disclosures often lead to scanning, probing, and automated attacks shortly afterwards.

One outdated plugin can undo layers of good work elsewhere.

🤔 When was the last time you checked whether the set and forget parts of your website were still being maintained?
