Pyersinia is a similar tool to Yersinia, but Pyersinia is implemented in Python using Scapy. The main objective is the realization of network attacks such as spoofing ARP, DHCP DoS , STP DoS among others. The community can add new attacks on the tool in a simple way, using plugins. This is because Pyersinia uses the STB (Security Tools Builder) framework.

Adding new attacks on the tool is a simple task because we use the framework STB (Security Tool Builder). The new attacks are added by plugins.

You can contribute for this project easily. First you have to add your REQUIRED parameters into pyersinia.py file if they are not. Second you have to add in the api file as a plugin your import attack. At the end, you have to add your plugin in ./pyersinia_lib/libs/plugins folder. This plugin should have 2 functions at least:

• run_attack(config)
• run(your parameters)

In run function you will include your new attack.

If you need switch or router to taste your plugins, you will have to install gns3 to virtualize them.

Install pyersinia is so easy:

$ python -m pip install pyersinia

Or install from Pypi:

# pip install pyersinia

You can display inline help writing:

> python pyersinia.py -h
