As you review your inbox, you may come across an important email containing a Word document attachment. This could be an invoice, a message from a supplier or a request from a colleague. Without hesitation, you open the file, unaware that you may have just fallen victim to a sophisticated cyber attack.
This is precisely what cyber criminals anticipate. They have devised a new technique to bypass even the most advanced email security filters, by exploiting corrupted Microsoft Word files.
This method is both sophisticated and highly dangerous.
Phishing, a prevalent form of cyber crime, is designed to deceive individuals into disclosing sensitive information, such as passwords or banking details. Attackers often disguise their fraudulent attempts as legitimate communications from trusted sources, including banks, colleagues or well known companies.
These deceptive emails typically contain attachments or links. Opening the attachment or clicking the link may inadvertently download malicious software (malware) or redirect you to a counterfeit website designed to steal your credentials.
Phishing attacks continue to evolve and remain one of the most effective tactics cyber criminals use to infiltrate businesses. While email security filters are generally capable of detecting threats, corrupted files can evade these safeguards due to their inability to be properly scanned.
Upon opening such a file, Microsoft Word attempts to “repair” it, presenting what appears to be a standard document. However, the file may contain a malicious QR code or link that directs you to a phishing site, often a fraudulent Microsoft 365 login page. Entering your credentials in this deceptive interface could grant cyber criminals access to your account, potentially compromising your entire organisation.
The theft of a single employee’s login credentials can be enough for attackers to access sensitive customer data, restrict access to critical business files or use the compromised account to launch further phishing campaigns against your contacts.
The consequences of such an attack can be severe, resulting in financial losses, legal liabilities and irreparable reputation damage.
As cyber attacks grow increasingly sophisticated, businesses must remain vigilant. However, you do not need to be a cyber security expert to protect your organisation. The most effective defense is awareness and caution.
To mitigate the risk of phishing attacks, consider the following best practices:
- Pause and assess before opening attachments or clicking links, especially if an email seems unexpected.
- Be wary of urgency, scammers often use high-pressure tactics to provoke rushed actions.
- Verify suspicious emails by contacting the sender directly through a trusted communication method.
- Do not assume legitimacy based on an email’s appearance, attachments and links can be easily manipulated.
- Educate your team on phishing threats, ensuring they understand the risks and know how to identify warning signs.
