OWASP Honeypot

In our first test of the OWASP Honeypot with Ali Razmjoo, I am gonna say that among all attacks we are receiving, Russians are doing it smarter and more effective

Black Hat Asia 2019

Our OWASP Nettacker: Automated Penetration Testing Framework has been accepted for Black Hat Asia Arsenal 2019.

https://www.blackhat.com/asia-19/arsenal/schedule/index.html#owasp-nettacker-automated-penetration-testing-framework-14336


The OWASP Nettacker project was created to automate information gathering, vulnerability scanning, and eventually generating a report for networks, including services, bugs, vulnerabilities, misconfigurations, and other information. This software will utilize TCP SYN, ACK, ICMP and many other protocols in order to detect and bypass Firewall/IDS/IPS devices. By leveraging a unique method in OWASP Nettacker for discovering protected services and devices such as SCADA, it would make a competitive edge compared to other scanners, making it one of the best.
