What is Clone Phishing?

Clone phishing is a type of Phishing attack in which a legitimate, and previously delivered, email containing a link or attachment has had its content and recipient address(es) stolen by a malicious hacker and used to create an almost identical, or “cloned”, email.

The legitimate attachment or link embedded in the email is replaced with a malicious version and then sent from a spoofed email address, so it appears to come from the original sender. Clone phishing can refer to a previous message that the recipient sent to the legitimate sender.

What Does Clone Phishing Look Like?

  • Sent from an email address spoofed to appear to come from the original sender
  • The attachment or link within the email is replaced with a malicious version
  • It may claim to be a resend of the original or an updated version to the original.

Tips & best practices for recognizing & defending against Clone Phishing attacks:

  • If an email appears strange in any way, contact the sender with a phone call to confirm the legitimacy of the email.
  • If you receive an email from a source you know but it seems suspicious, contact that source with a new email, rather than hitting “reply”.
  • Scan all attachments for viruses or malicious code.
  • Verify shared links to ensure that they do not lead to fraudulent websites or dangerous code.
  • Check for spelling and grammatical errors which can indicate that an email is fraudulent or malicious. Also, keep an eye out for suspicious subject lines and signatures.
  • Think before you act! Take adequate time to thoroughly evaluate each email you receive before clicking on links or downloading attachments. For example, ask yourself: Does an order confirmation email you’ve received correspond to a recent purchase you have made? Do the sender and recipient addresses make sense?
