Link is Malformed

Description: We are unable to process the clicked link because it cannot be validated as genuine.

PhishProtection links are cryptographically signed to prevent tampering. Some email clients are known to either truncate long URLs (Microsoft Defender SafeLinks has the same limitation) or alter the encoding of certain types of links, which then fail to pass the cryptographic hash check on our side when the link is clicked.

Unfortunately we cannot alter or remove this cryptographic check, as it protects against attackers using our link scanning infrastructure as an open redirect relay by changing the "url" component of rewritten links to point to a site of their choosing.

Solution: 

• Try a different email client, or if your client supports it open the email message in a web browser window.
  
  
• Save the email message as a .eml file (with intact headers and MIME sections) and open a ticket with DuoCircle support for assistance with troubleshooting the source of the issue.
