If a member of staff left tomorrow, would everyone know where critical documents are stored?

Good IT isn't just about security.

It's about making information accessible, organised and backed up.

Deepfake Scams: Could Your Staff Spot One?

In 2024, an employee at a global engineering firm was tricked into transferring $25 million after joining a video call with what appeared to be senior company executives. Every person on the call was actually an AI-generated deepfake. It almost sounds impossible but unfortunately it is true:

As AI technology improves, criminals are no longer relying solely on fake emails. They can now clone voices, create realistic video calls, and impersonate trusted colleagues.

Imagine receiving:
A voicemail from your Managing Director asking for an urgent payment.
A video call from a client requesting sensitive information.
A voice note from a colleague asking you to reset a password.

It might not be them but how can you tell?

We would suggest verifying an unexpected payment or data request through a separate communication channel. Start training staff to question unexpected messages, even from familiar voices and implement approval processes.

Sadly, just as we are all starting to get good at spotting the phishing emails cyber security has evolved.

Tech Tip: Don't Store Important Files Only on Your Desktop

Is your desktop full of important documents, spreadsheets, photos, and customer files?

While it might be convenient, storing important files only on your desktop can be risky. If your computer fails, is lost, stolen, or hit by ransomware, those files could disappear in an instant.

Always store files in OneDrive, SharePoint, or another cloud backup solution

Think of your desktop as a workspace, not a filing cabinet.

Many people imagine cyber attacks taking days or weeks to cause damage. The reality? The first 10 minutes can be enough for attackers to gain access, steal data, spread malware, or compromise multiple systems.

Minute 1: A malicious email is opened or a compromised account is accessed.
Minutes 2-3: Attackers begin exploring the environment, identifying users, devices, and valuable data.
Minutes 4-6: Privileges may be escalated, allowing wider access across systems and networks.
Minutes 7-8: Sensitive information can start being copied, encrypted, or prepared for exfiltration.
Minutes 9-10: The attack spreads, backups may be targeted, and business disruption begins.

The good news? Fast detection and response can stop an attack before it becomes a full-scale incident. That's why businesses should have:

Multi-Factor Authentication (MFA)
Regular security awareness training
Endpoint protection and monitoring
Secure backups
An incident response plan

Cybersecurity isn't just about prevention, it's about how quickly you can spot and contain a threat.

A single click doesn’t automatically mean your device has been hacked or your business has been compromised. However, what you do in the next few minutes can make a huge difference.

Myth: More Bars on Wi‑Fi Means Faster Internet

Wi‑Fi bars only show the strength of the signal between your device and your router. They don't measure your actual internet speed.

Even with a full signal, your connection can still feel slow because of:
Internet provider issues
Network congestion
Too many devices connected
Background downloads or updates
An older router

Quick Tip: If your internet feels sluggish, run a speed test before blaming the Wi‑Fi signal. The issue may not be your wireless connection at all.

Did you know?

Phishing emails are linked to over 90% of successful cyber attacks.

Most cyber incidents don’t start with hackers breaking in, they start with someone clicking an email.

Windows has a hidden feature called Clipboard History that lets you access multiple things you’ve copied, not just the last one.

Windows Key + V shows you a list of your recent copied items and lets you paste anything you’ve copied earlier. It works with text, links, and even images.

If you’re not using this already give it a try, it’s one of those small changes that makes a big difference.

Myth: Macs Cannot Get Viruses

You’ve probably heard it before: “I’ve got a Mac, so I don’t need antivirus.”
The truth is, Macs absolutely can get viruses and other types of malware.

For years, Macs were seen as “safer” because fewer people used them, so attackers focused on Windows instead. Apple built strong security features into macOS and marketing reinforced the idea of being virus-proof
But that never meant Macs were immune, just less targeted at the time.

Things have changed:
Macs are now widely used in business and everyday life. Cybercriminals are actively targeting macOS. MacOS does have some very strong built-in protection, but it is not fool-proof with attackers often rely on tricking users rather than breaking the system itself.

We suggest treating your Mac like any other device:
Keep it updated
Be cautious with downloads and email attachments
Use antivirus or endpoint protection
Train users (especially in business environments)
