Introducing the OWASP Nettacker Project

Introducing the OWASP Nettacker Project

OWASP Nettacker project was created to automate the information gathering, vulnerability scanning and in general to aid the penetration testing engagements. Nettacker is able to run various scans using a variety of methods and generate scan reports for applications and networks, including services, bugs, vulnerabilities, misconfigurations, default credentials and many other cool features - for example an ability to chain different scan methods. This relatively new (Summer 2017) and a lesser-known OWASP project has generated a huge amount of interest at BlackHat Europe 2018 Arsenal live demo gathering massive crowds of seasoned hackers and penetration testers eager to see this new tool in practice. This talk will showcase the OWASP Nettacker project giving an overview of its features including the live demo of the tool.

  1. Introducing OWASP Nettacker Sam Stepanyan
 OWASP London Chapter Leader

    Twitter: @securestep9 SAM STEPANYAN
  2. $ whoami - Sam Stepanyan Software development background OWASP London

    Chapter Leader Application Security Consultant, Financial Services I am a Defender Why am I presenting a talk about a tool 
 which consists of words “Network” and “Attacker”??? @securestep9
  3. Dr Greg Fragkos (@drgfragkos) and I were asked to demo

    OWASP Nettacker at BlackHat Europe2018 as Nettacker project leaders could not get to London in time. We had to learn the tool overnight to be able to demo it at BlackHat Arsenal. Then this happened ==> @securestep9
  4. OWASP NETTACKER PROJECT OWASP Nettacker is an open source software

    tool which assists with Penetration Testing by automating Information Gathering and Vulnerability Scanning tasks
 This software can be run on Windows/Linux/MacOS under Python (2 & 3) Coded in @securestep9

    each other can they be all used together??? “SWISS ARMY KNIFE”? @securestep9
  8. •a collection of tools •modular structure •create own modules •fast

    perfomance / multi-threading •customisable profiles (bundle of modules focused on specific task) •automate and run from command line WHY OWASP NETTACKER @securestep9
  9. it is not “officially released” yet not even in “beta”

    - v0.0.1 looking for more contributors …however it already has: command line interface Web UI API Report generator Maltego transforms 62 modules (+1) @securestep9 OWASP NETTACKER
  10. RESPONSIBLE USE WARNING You shall not misuse this tool nor

    any other security tool for unauthorized access Performing security scans without permission from the owner of the computer system is illegal. @securestep9
