AntiPhish is a client-server system for detecting phishing websites. The architecture consists of a client-side browser extension for Mozilla Firefox and a server-side RESTful web service implemented using Dropwizard.

When a website is called by the browser, the extension sends the requested URL to the server and triggers the analysis process. It currently consists of a total of four superordinate analysis steps and evaluates the website belonging to the transmitted URL on the basis of certain heuristics. The calculated overall result is assigned to a green, yellow or red traffic light symbol, which is then visually displayed to the user in the browser as a measure of the outgoing phishing threat. The results of the evaluation of the system showed an accuracy of 84.17%, with a sensitivity of 78.13% and a specificity of 90.22%.

Installation Instructions

In order to run the system, both the client and the server application must be started.

Client - Mozilla Firefox browser extension

The browser plugin can be loaded as a temporary add-on. Therefore open "about:debugging" in Firefox, click "Load Temporary Add-on" and select any file in the extension's directory.

Server - Dropwizard RESTful web service

The Dropwizard service is built as a “fat” .jar file (contains all of the .class files required to run the service) using Maven. This file can be found in the folder target and can be built and started as follows:

  1. Run mvn clean install to build the application
  2. Start application with java -jar target/antiphish-0.0.1-SNAPSHOT.jar server config.yml
  3. To check that the application is running enter url http://localhost:8080


AntiPhish was implemented in the course of a master thesis at the Alpen-Adria University Klagenfurt. The thesis can be found in the folder docs (chapter 4-7, German only).
