You’re scanning your inbox and spot an important email with a Microsoft Word attachment. It looks like an invoice, a message from a supplier, or a request from a colleague. Without a second thought, you open it.

Just like that, your business is at risk.

Cybercriminals are using a new phishing tactic to bypass even the most advanced email security filters—corrupted Microsoft Word files. This method is designed to trick users into opening a seemingly harmless document that leads to credential theft, data breaches, and financial losses.

How This Phishing Attack Works

Phishing attacks are a major cybersecurity threat, especially for businesses that rely on email communication. In this latest variation, scammers send an email that appears to be from a trusted source, such as a client, vendor, or internal department. The email contains a Word document that has been deliberately corrupted.

Because the file is damaged, traditional email security filters may fail to scan it properly. Once the recipient opens it, Microsoft Word automatically “repairs” the document, making it appear legitimate. However, hidden within the file is a malicious QR code or phishing link—often leading to a fake Microsoft 365 login page.

If an employee enters their credentials, the attacker gains access to business systems, emails, and potentially sensitive customer data.

Why This Matters for Your Business

All it takes is one compromised login for cybercriminals to infiltrate your network. With unauthorized access, they can:

  • Steal customer and financial data
  • Lock employees out of essential files
  • Deploy ransomware, demanding payment to restore access
  • Send fraudulent emails from your domain to deceive clients and partners

A single phishing attack can lead to financial losses, legal liabilities, and reputational damage—all of which can be costly and difficult to recover from.

How to Protect Your Business from Phishing Attacks

Cyber threats are evolving, but with the right precautions, you can minimize the risk. Here’s how:

✅ Verify Before You Click – Always double-check email attachments and links before opening them, especially if they come from an unexpected source.

✅ Beware of Urgency – Scammers rely on pressure tactics to make you act quickly. If an email demands immediate action, take a step back and verify it.

✅ Train Your Team – Educate employees on phishing red flags, such as misspelled domains, unexpected attachments, and requests for sensitive information.

✅ Use Multi-Factor Authentication (MFA) – Even if a password is compromised, MFA can prevent unauthorized access.

✅ Implement Strong Email Security – Advanced email filtering solutions can help detect and block malicious attachments before they reach inboxes.
