Phishing Reporter
Phishing Reporter helps users to report the suspicious email for analysis and start an incident investigation with Incident Responder.
To run phishing reporter add-in, make sure you have all pre-requisites of Visual Studio 2010 Tools for Office Runtime.
The main function of Phishing Reporter is to make users easily report suspicious emails to their incident responder. When a user detects a suspicious email by clicking on the Suspicious Email Reporter button, he/she reports it to the incident responder module for analysis. Then, the platform investigates this suspicious email either by its own engine or with third-party integrated services. Click to see “ How does an investigation mechanism work?”

How Does the Add-in Work?

In Outlook, where the add-in is installed, the working principle works as follows:
  1. 1.
    When add-in opened:
    a. Sends a heartbeat to server
    b. Get order from the server, if there was an investigation or action
  2. 2.
    When add-in runs:
    a. Sends the heartbeat to the server in periodic time [1]
    b. If any order comes from the server, then start to do this investigation or action [2]
    c. If an error occurred then it logs it to the client-side then send it to our server
  3. 3.
    When outlook closes itself, then add-in close:
[1] The add-in optimizes this process according to network and machine performance by itself.
[2] When conducting the investigation, the add-in optimizes this process according to the computer and the network situation.
