Malicious email attacks continue to be a common security threat to individuals and businesses, with small businesses being targeted most often.

Email messages asking recipients to click on unknown links or attachments are especially dangerous because the sender oftentimes impersonates a leader or another member of your organization.  Common requests can include:

  • Making a financial payment
  • Altering the bank account information of a vendor, client, or another team member
  • Purchasing gift cards 
  • Resetting your passwords

To prevent intrusion and thousands of dollars in recovery costs, we’ve put together some best practices for you to share with your teams, family, and friends as these types of attacks become more common.  

Security Tips to Avoid an Attack

  1. Never open links from unknown senders.
  2. Never disclose sensitive information over the telephone.
  3. Do not make any requested purchases, money transfers, or banking account changes without personally verifying the request with the sender. This should be done via telephone or an in-person conversation.  
  4. Never input a username or a password unless you’re 100% sure of the requester’s legitimacy.
  5. Never download attachments from unknown senders.
  6. Always use long, complicated and unique passwords.
