Email phishing prevention should be a priority. Imagine this: You’re scanning through your inbox and see an urgent email from a trusted supplier. There’s a Word document attached — maybe an invoice or an order form. Without a second thought, you open it. Just like that, you’ve potentially fallen victim to a phishing attack.
This is exactly the scenario cybercriminals rely on. They’ve become increasingly sophisticated, using corrupted Microsoft Word files to bypass even the most advanced email security filters. If your business isn’t aware of these tactics, you could be at significant risk.
What is Phishing?
Phishing is a form of cyber attack where scammers attempt to steal sensitive information — such as login credentials or financial data — by posing as a trusted entity. These attacks often come via email, appearing as legitimate messages from colleagues, suppliers, or organisations you know.
Opening an attachment or clicking a link within these emails can lead to malware installation or direct you to fake websites designed to steal your information. Phishing attacks are a leading cause of data breaches worldwide.
The Rise of Corrupted File Phishing
Cybercriminals are now exploiting corrupted Microsoft Word files to slip past email security systems. Typically, email filters can scan attachments for malware, but when a file is “corrupted,” it can’t be analysed properly. This creates a gap for malicious attachments to reach your inbox.
When you open one of these corrupted files, Microsoft Word attempts to “repair” it, making the document appear normal. Hidden within the document, however, could be a malicious QR code or a disguised link leading to a phishing site — often a fake Microsoft 365 login page. If an unsuspecting employee enters their details, the attackers can gain access to your systems.
The Consequences of a Phishing Attack
A single compromised account can lead to severe damage. Cybercriminals with access to your systems could:
- Steal sensitive customer or company data
- Lock your team out of essential files, demanding a ransom for access
- Use your email to send phishing attacks to your contacts, damaging your reputation
Without sufficient prevention systems, a successful attack could lead to financial losses, legal repercussions, and a long-term impact on your business’s reputation.
How to Strengthen Your Email Phishing Prevention
Fortunately, you don’t need to be a cyber security expert to protect your business from phishing attacks. Awareness and caution go a long way. Here’s how to bolster your defences:
✔ Slow Down and Think — Never open attachments or click links in emails you weren’t expecting. Take a moment to verify the sender.
✔ Beware of Urgency — Scammers create a sense of urgency to pressure you into quick decisions. If an email demands immediate action, be cautious.
✔ Verify Unexpected Emails — If an email appears to be from a trusted source but seems unusual, contact the sender through a separate communication channel.
✔ Examine Attachments and Links Carefully — Malicious links may be disguised as legitimate ones. Hover over links before clicking to check the URL.
✔ Educate Your Team — Regular training on phishing tactics and warning signs is essential. Employees should know what to do if they suspect a phishing attempt.
