Suspicious message report processing and threat response

A computerized system for suspicious message processing and incident response, comprising:

• a processor configured for executing instructions at a messaging client, the computer-executable instructions for:
• receiving a user interface action by a user indicating that a message delivered in an account associated with an individual has been identified by the user as a potential security threat;
• determining whether the delivered message is a known simulated phishing attack based on an identifier or other message characteristic of the delivered message;
• if the delivered message is determined to be a known simulated phishing attack based on the identifier or other message characteristic of the delivered message, then not transmitting a copy of the delivered message to a detection platform;
• and
• if the delivered message is determined not to be a known simulated phishing attack based on the identifier or other message characteristic of the delivered message, then transmitting a copy of the delivered message to the detection platform;
• a processor configured for executing instructions at a threat detection platform, the computer-executable instructions for:
• receiving the transmitted copy of the message at the threat detection platform;
• electronically storing a pattern as a rule for determining whether a body of the received message or an attachment of the received message contains a defined textual or binary pattern associated with a security threat;
• processing the received message according to the electronically stored rule to determine whether the body of the received message or an attachment of the received message contains the defined textual or binary pattern associated with a security threat;
• assigning a further processing action to the received message based on the determination of whether the received message contains the defined textual or binary pattern;
• associating the received message with a message group, the message group being defined by having at least the defined textual or binary pattern in common with the received message;
• and
• displaying a graphical representation of the message group, each of the group of messages displayed having been determined not to be a known simulated phishing attack based on the identifier or other message characteristic of the delivered message.
