You’re scanning your inbox and 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. You open it without thinking twice… and just like that, you’ve been scammed.

This scenario is exactly what cyber criminals are counting on. Now they’ve come up with another new way to get past even the most advanced email security filters – this time, using corrupted Microsoft Word files.

It’s a clever and dangerous tactic.

Phishing (pronounced "fishing") is where scammers try to trick you into giving away sensitive information, like passwords or bank details. They “bait” you with an email that looks legitimate, maybe from your bank, a co-worker, or a company you trust.

These emails often include attachments or links. When you open the attachment or click the link, you could be downloading malicious software (malware) or visiting a fake website designed to steal your details.

Phishing attacks are constantly evolving, and they’re now one of the most common ways scammers break into businesses. Email security filters are usually pretty good at scanning attachments. But since corrupted files can’t be analysed properly, the Word file is able to sneak into your inbox.

When you open one of these corrupted files, Microsoft Word will “repair” it and show you what looks like a normal attachment. But the document will contain a malicious QR code or link that sends you to a phishing site (often a fake Microsoft 365 login page). If you enter your details, scammers could have access to your account – and potentially your entire business.
