Projects / Hyenae


Hyenae is a highly flexible and platform independent network packet generator. It allows you to reproduce low level Ethernet attack scenarios (such as MITM, DoS, and DDoS) to reveal potential security vulnerabilities of your network. Besides smart wildcard-based address randomization, a highly customizable packet generation control, and an interactive attack assistant, Hyenae comes with a clusterable remote daemon for setting up distributed attack networks.
