Abstract
Systems and methods are described for detecting a simulated phishing message by an email client plug-in. A unique key is received at the email client plug-in. An indication that an email was reported by a user as a suspicious message is received at the email client plug-in. The email is a simulated phishing message having the unique key mapped by cryptographic hashing function into a hash value in a predetermined field in the header of the simulated phishing message. The presence of the predetermined field is detected and the hash value in the predetermined field is compared to a result of applying cryptographic hashing function to the unique key received by the email client plug-in. Responsive to being matched to the result, it is determined that the suspicious message is a simulated phishing message generated by a server.
