Cybercriminals are constantly refining their tactics to bypass security measures, and a new phishing technique involving corrupted Microsoft Word files is now on the rise. Even the most advanced email security filters can struggle to detect these threats, making it easier for malicious attachments to reach unsuspecting users.
Phishing scams are designed to trick users into revealing sensitive information, such as login credentials or financial details. These attacks often arrive in the form of emails that appear to be from trusted sources, such as colleagues, suppliers, or financial institutions.
A common phishing tactic involves sending an email with an attachment—often a Word document—that appears to be an invoice, a contract, or a legitimate business request.

Once opened, Microsoft Word attempts to "repair" the document, displaying what looks like a normal file.
Hidden within the document, however, is a malicious QR code or link that redirects users to a phishing site—frequently a fake Microsoft 365 login page. Entering login credentials on this site gives hackers access to business accounts, potentially exposing sensitive customer data, financial records, or internal communications.
