Think Twice Before Opening That File
You’re scrolling through your inbox when you spot an important email with a Word document attached. Maybe it’s an invoice, a message from a supplier, or even a request from a colleague. Without thinking twice, you click to open it… and just like that, you’ve been scammed.
This is exactly what cyber criminals are counting on. And now, they’ve found an even more devious way to bypass advanced email security filters—using corrupted Microsoft Word files.
It’s a clever and dangerous tactic, and it’s catching many businesses off guard.
How This New Email Scam Works
Cyber criminals use a tactic called phishing (pronounced “fishing”)—tricking you into revealing sensitive information like passwords, financial details, or company data.
They do this by sending an email that appears legitimate—often mimicking banks, suppliers, or even colleagues—with an attachment or link. Once you open it, you could unknowingly install malware or be directed to a fake website designed to steal your login details.
So, what makes this latest attack different?
Email security filters are usually very good at scanning attachments for malware. But corrupted files can’t be analysed properly—which means they slip through undetected.
When you open a corrupted Word document, Microsoft Word automatically “repairs” the file and presents it as normal. But hidden inside could be:
🔴 A malicious QR code leading to a phishing site
🔴 A dangerous link disguised to look like a trusted website
🔴 A prompt to enable macros, which can install malware on your device
One of the most common tricks? A fake Microsoft 365 login page. If you enter your details, you’ve just handed over access to your business systems.
The Consequences Could Be Devastating
Scammers only need one employee to fall for the trap. Once inside your cloud systems, they can:
- Steal customer data, exposing your business to legal and financial consequences
- Lock your team out of essential files with ransomware, demanding payment to regain access
- Send phishing emails from your account, tricking your colleagues and clients into the same scam
The impact of an attack like this can be catastrophic—financial losses, data breaches, legal trouble, and reputational damage that could take years to recover from.
How to Protect Your Business
Cyber threats are getting more sophisticated, but you don’t need to be a cyber security expert to stay safe. The best defence is awareness and caution.
Follow these simple steps to reduce your risk:
✅ Pause before opening attachments or clicking links. If you weren’t expecting an email, be suspicious.
✅ Watch out for urgency. Scammers pressure you into acting fast—don’t fall for it.
✅ Verify unexpected emails. If something seems off, contact the sender directly using a trusted phone number or website.
✅ Don’t trust an attachment or link just because it looks professional. Cyber criminals can fake branding to make emails seem legitimate.
✅ Educate your team. Make sure everyone in your business understands phishing risks and knows what warning signs to look out for.
