What is a phishing email?

A phishing email is a fraudulent message designed to trick the recipient into sharing sensitive information or downloading malicious software. Cyber criminals often impersonate trusted organisations or individuals to lure victims into taking action.

Common signs of a phishing email

1. Suspicious sender address

Phishing emails often come from addresses that look legitimate at first glance but contain subtle differences. For example, swapping out letters or using domains like .net instead of .com. Always check the sender’s email address carefully.

2. Poor spelling and grammar

Legitimate organisations usually proofread their communications. If you notice repeated spelling mistakes, clumsy sentence structure or unusual formatting, it may be a phishing attempt.

3. Urgent or threatening language

Phrases like “your account will be suspended” or “immediate action required” are designed to create panic and pressure you into clicking links without thinking.

Hover over any link before clicking. If the URL looks unusual, mismatched or shortened to hide its true destination, treat it as a warning sign.

5. Unexpected attachments

Phishing emails often contain attachments such as invoices or documents that, once opened, release malware onto your device. Only open attachments you were expecting from a trusted source.

6. Requests for sensitive information

Legitimate companies will never ask for login credentials, bank details or personal information by email. Treat such requests as an immediate red flag.

How to protect yourself from phishing emails

  • Always verify the sender before clicking links or opening attachments.
  • Use multi-factor authentication (MFA) where possible.
  • Train your staff regularly on recognising phishing threats.
  • Keep software and security tools up to date.
  • Report suspicious emails to your IT or security team.
