OWASP Nettacker project (a portmanteau of "Network Attacker") is a relatively new yet an awesome and powerful 'swiss-army-knife' automated penetration testing framework fully written in Python. Nettacker recently gained a lot of interest from the European and Asian penetration testing communities and was even included in the specialist Linux distribution for penetration testers and security researchers. 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 talk will feature a live demo and several practical usage examples of how organisations can benefit from this OWASP project for automated security testing
