EC521: Cybersecurity OpenVAS Agenda What we have done? How OpenVAS work? Mailbox Browser Web application with XSS vulnerabilities What to do next… 2

EC521: Cybersecurity OpenVAS What we have done? We were divided into 4 parts and each in charge of web server, web application, mailbox, and web browser. learning the basic protocols that running on the contemporary Internet(basic knowledge charging) Research (a lot of reading): – OpenVAS – documentation – How to setup and run the OpenVAS – Understanding the vulnerability of Mailbox Coding – Web Application – Writing scripts 3

What we have done? Build up the working environment Kali linux OS(set up on virtual machine) install openVAS in Kali linux Find and study(then maybe audit) open source files to set up our targets(i.e. mailbox etc.) Use openVAS to give initial test scan to these targets Then figure out how we can utilize these vulnerability 4

EC521: Cybersecurity OpenVAS 14 Target – Xampp/DVWA

EC521: Cybersecurity OpenVAS 15 XAMPP's name is an acronym for: X (to be read as "cross", meaning cross-platform) Apache HTTP Server MySQL PHP Perl xampp

DVWA Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is damn vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, help web developers better understand the processes of securing web applications and aid teachers/students to teach/learn web application security in a class room environment.

EC521: Cybersecurity OpenVAS 31 First Try

EC521: Cybersecurity OpenVAS Webmail vulnerability Next… Keep digging vulnerabilities (Maybe elder ver.) Patches & Penetration (Burpsuite) Localhost =>LAN 32

EC521: Cybersecurity OpenVAS 33 Web Application (Blackboard)

EC521: Cybersecurity OpenVAS DEMO: Web Application (Blackboard) Description: Blackboard is the web application used by students to post their homework solutions, which vulnerable to XSS and CSRF attack. 34

EC521: Cybersecurity OpenVAS DEMO: Web Application (Blackboard) Story on behalf: You (hacker) don’t know solution to the homework and want to steal the solutions from others. Also you want to steal final exam questions from teacher in a such way that no one will find out that it was you. (i.e. like a ninja) 35

EC521: Cybersecurity OpenVAS DEMO: Web Application (Blackboard) Mission: 1.Steal the solutions from “nerd”; 2.Make “badguy” to steal final exam q/a for you; 3.Be the smartest guy (ninja, hacker) in the class; 36

EC521: Cybersecurity OpenVAS DEMO: Web Application (Blackboard) Wait a minute…where is OpenVAS??? We will make security assessment on our web application using OpenVAS. (in near future) 37

EC521: Cybersecurity OpenVAS What to do next… Write plugins – OpenVAS Integrate everything Modify the php code in DVWA, do the openvas scan again, compare the report Local => LAN; Penetration (Burpsuite) and Patches 38
