How To Identify Malicious Email Attachments

Malicious email alert

Do you know that more than 50% of cyber attacks are due to employee error and negligence, and part of that negligence and errors are due to the opening of malicious attachments, and the employee’s inability to identify a malicious attachment? Well, I’m here today to give you a few tips on how you and your employees can identify those malicious attachments. 

One, always listen to your malware alert. If your email service or your antivirus software tells you not to open the attachment, don’t open the attachment, listen to it! 

Two, check out the message. Do you know who actually sent you the attachment? If you don’t know who sent you the attachment, maybe it’s best not to open the attachment. Does the email content actually look normal? Or look like most of the emails that you get? Is it jumbled? Are there misspellings? Is your name misspelled in it? Those are pretty good signs that the attachment is in fact malware. 

Check out the attachment file extension. If it is a .exe, don’t open it. That’s an executable file and you do not want to open it in your email. Other attachment file extensions that are most likely malware are the .docm extension, the .xlsm extension and the .pptm extension. If you see those, I wouldn’t open the attachment. Just be careful and think twice before you open any attachment. 

And lastly, always, always make sure that your antivirus software is up to date and current.
